I think most of us looked at Lil'Gun after reading the load data provided by Hodgdon. It is without a doubt the greatest powder every made for the 218 Bee in rifles with those copper covered bullets.

In the 357 S&W Magnum it has delivered great accuracy and the highest velocity with the least pressure of any powder I have found. And does it in both my Colt “Three Fifty Seven” and a Martini single shot with Lyman's #358156, solid and HP's. And it is a LOUD powder, not much flash, but bore pressure is certainly high at the muzzle of the rifle.

My problem is trying to get any kind of accuracy out of the 32/20 rifles or 32 H&R Magnum pistols with cast bullets. I have used RCBS 98 grain SWC, Lyman's #311316, #311008 and #311576.  They all shoot good with Bullseye, WW231, Unique and the rifles SR4759.

One thing I have learned is that as the sectional density gets higher (longer for caliber) you have to reduce the charge a lot. In the 32/20 going from the 120 grain to the 150 #311440, Lil' Gun has no advantage on SR4759 or IMR42247. But for the 115 grain #311316 it is 300 f/s faster than anything else. I just wish I could make it shoot better than 5 inch groups at 100 yards.

I wuz told on “Cast Boolits” that Lil Gun will erode your revolvers throat with a single shot, and ruin your barrel. They wouldn't lie, they're the best. I used it for years in heavy 45 Colt loads without issue, other than having the front sight hit me on the noggin. I must admit that I've never seen pressure test data on it before, but I don't recall having any high pressure concerns with the .loads I used.

Dan, I've only worked with Lil'Gun where it is appropriate. The list of pressure tested cartridges was in reply to Daryl's question:

"Interesting - have you tried this graphing with any other powders?"

I'm just trying to explain why fellows are seeing high pressure indicators in advance of a suggested max load. I personally will not shoot this powder over a 93% case density.

I agree with Daryl on Hornet performance. I've shot the 35gr V-Max up to 150yrd on prairie dogs for 5 years. My load is what I stated in my post at the top of this thread. It is a compressed load and I have never seen a high pressure sign with most likely 4,000 - 5,000 rounds shot.

I believe the Lil'Gun may not have applications in the other cartridges that Ranch Dog is listing, since H110 is the recommended powder for most magnum handgun type cartridges. I also haven't had any positive experiences with Lil'Gun in reduced load rifle cast bullet loads.

I thank Ranch Dog though for the pressure data he has showed us. I've tried Lil'Gun in 44 Mag with limited results and now will forget about any further trials of my own and stick with H110 or H4227 for magnum loads. B) ..................Dan

Brass can make a big difference in the Hornet. WW brass has 1gr. less capacity than RP brass. Too, WW brass, even though thicker, is less strong - another annomoly.

Consider that a WW “K” Hornet has the same capacity as a normal RP Hornet case.

Lil'Gun is the single best thing ever to happen to a .22 Hornet or .218 Bee.

A Lee “Factory Crimp Die” must be used however and then accuracy and shot to shot uniformity is unparalleled - no other powder can match it for speed and accuracy although W296 does come close in the it's heaviest charges.

I've pressure tested the following Hodgdon powders:

<>BL-(C)2 <>Benchmark <>H110 <>H322 <>H335 <>H4198 <>H4227 <>H4895 <> Lil' Gun <>Varget Those powders were tested in Marlin rifles chamber in the following calibers:

<>218 Bee <>25-20 Win <>30-30 Win <>30-30 Ackley Improved <>308 Marlin Express <>32-20 Win <>32 Win Spl <>35 Rem <>356 Win <>375 Win <>41 Mag <>44 Mag <>444 Marlin <>45 Colt <>45-70 Govt <>450 MarlinLil'Gun was the only powder that demonstrated the “sine wave” pressure curve. I have discussed this with a few “powder smart” guys and they feel it has something to do with the primer blowing the powder forward against the bullet before the wad of powder ignites.

I'm a bit nutty about the FCD. I use them with all the cartridges I reload except the semi-auto pistol calibers that I'm shooting cast bullets. I do not use the Pistol FCDs with the 41 Mag, 44 Mag, or 45 Colt as the carbide sizing ring defeats the efforts of an over bore cast bullet. Instead, I special ordered rifle type collet FCDs for these three calibers for use in my Marlin rifles.

My Lil'Gun ride was with the 41 Mag in my Marlin 1894PG behind my TL411-255-RF. I found it extremely unpredictable and dropped its use. Here is a summary of my pressure testing.

I will gine Lilgun a try in my 22 Hornet. An attempt to use it for .410 shotshell was disasterous as there were many case separtions.

Following up on my original post. Wasn't weak primers. Loaded once to fireform, second load was the Hodgdons near max load for K-hornet, pockets are GONE. Primers are inserted by hand, then just fall out. Like a SP in a LP pocket fall out!

My contender chamber is too tight to afford the luxury of added powder capacity. LilGun makes velocity but is PICKEY especially with the Hornet and a NON-bolt gun.

Heh guys, I've switched from 2400 in both my .357s and .45 Colts. Works great. 16.0 behind a 180 gr. LBT in the .357 GP-100 and a Marlin 94 carbine. 20.0 behind a 300 gr. LBT WFN in .45 Colt in a Marlin Cowboy carbine. These are both pretty warm loads, so work up from below for sure.

I have used Lil gun only for my k-hornet pistol. At loads that are below listed for Hodgdons with 34 gr midsouth varmint nightmare, (another Fred at Bullberry super tight chamber) I blew primers one after the other and I mean BLEW. Velocities in a 10 inch barrel were at 3009 fps. Thats WAY faster than a 10 inch barrel can produce with that bullet. The moral of the story is, after conversing with Fred, the tighter the chamber, the less you can do. I have to use hornet data for k-hornet. The case capacity is worthless to me due to chamber size. But the brass life and headspace issues the Hornet is known for a still helped. It's a heck of a powder, it'll go fast but it's very sensitive. You go from a slightly flat primer @x.2 gr, a blown primer @x.4gr. when your at the threshold. There was no case stretching nor other case dimensional issues. I was using WSR primers which are fairly soft and give up early. I was told to try Fed Match pistol primers and try again, maybe the same charge weight was ok and primer failure had to do with primer (I don't think so though).

i have used 2400 in my 454 taurus raging bull and srh 44 mag with great results. this is bulky powder and usually fills the case at recommended loads

I'm lazy. I have no desire to spend my weekend at the range trying to develop the loading I need for my Casull, so I'll toss out the question and see if anyone has been down this road ahead of me. I am the recent proud purchaser of a 7.5” Ruger Super Redhawk, chambered in 454 Casull. I have reloaded for several years for my .45ACP and a .45 Colt, and I just shoot Unique in everything, but this high pressure shooter seems to be a different animal all together. I have about 1,000 Lazercast 250gr LRN bullets and what I would like to do is load these into some fresh 454 brass but at reduced (45 Colt) pressure. If your asking why not just load up .45 Colt brass, it's cuz I don't like the ring it produces at the top of the chamber. So; anybody have a good recipe? I assume some 454 Casull guys have tried Trailboss, but I can't find any published data for that load. Their is data for Lil Gun and even for the Alliant powders, but they seem to ignore the issue of all that case space with not much powder. Your suggestions would be appreciated. PS I did load some 44 Rem Mag rounds with a full case of Trailboss for my neighbor, using a lightly jacketed HP round, and the results were excellent.

Andy- by removing the magazine spacer at the rear, and grinding it down on the flat side, you can reduce the thickness to where the lower retaining pin just passes in front. Re-drilling the top pinhole 1/16” and replacing the guts, gives you a magazine that will feed longer bullets. : I use a spacer that replaces the magazine, and merely throw a round into the port and close the bolt, single-shot fashion. ; James Calhoon sells a 'comercial' spacer that does the same thing, replacing the magazine for smooth single feed. ; Questioning the guys over on http://www.saubier.com>www.saubier.com will reveal the sourse who re-models the mags and mag supports to convert them to 3 round, flush magazines. These have become so popular that CZ now incorporates this feature on some of the models - probably the American or 'custom' version.

Daryl, I routinely kill PDs out to 200 yards with my CZ and the 35 and 33 grn. V-Max. I guess that the way I shoot, off of a less than stable rest, keeps me from appreciating the relative inaccuracy of the V-Max. I never shoot much more than 200 with the Hornet and as feeding from the magazine is something I like, loading the 40 grain V-Max is out. I have shot them single feed and they work great. Frankly, this is a walking rifle and when I sit down to shoot past 200 I'm using a bigger gun. ~Andy

Andy, I gave up on the exceptionally accurate, but ballistic dud 35gr. Vmax. I found that accuracy, normally in the 3/8” range for 5 shots at 100meters, opened to 2” at 180yards. I've since changed to 40gr. Vmax and 40gr. Ballistic Tips for long range shooting, while the 40gr. Varminators or 40gr. VLC's work just fine for moderate ranges. : Best results so far, is a 454 yard ground squirrel with a 40gr. Nosler BT, with several ground squirrels (gophers) in between that and 354yards with the 40gr. Vmax.

I use Lil Gun in a pair of CZ 527 Hornets belonging to my son and I. With 13.0 grains and a 35 grain V-Max we are getting half MOA for three shots from Win Brass, Fed Small pistol primers, and Lee crimped. Velocity readings are impressive: 16 ft/sec total spread. It is my #1 prairiedog gun. ~Andy

Balhincher - several of my firends on Jim Saubier's small-bore forum for the “K” wouldn't accept the loads many of use were using in the standard case.  While with WW brass, in a strong bolt gun (CZ or Ruger bolt or SS) we're able to use up to 13.5gr. wiht WW brass and 14.3gr. in RP brass, those loads apparently produced excessive laods in several “K"'s - go figure. My RP Hornet brass, after 14 loadings of over 14.0gr. Lil'Gun from my CZ “Lux” have now been necked and fireformed to .17AH without loss - they've never been annealed - again. go figure. Pockets are almost identical to brand new brass - barely any different feel on seating primers, yet they've all been fired 15 times with a major foreforming to boot.  Brass life is generally the final word in safe pressures.  I also used nothing but pistol primers in the Hornet chambering, Unless laods are heavily crimped with a Lee fctory crimp die, SD's will vary enormously, but probably not more than W296 and other Hornet powders.  I've never had a pierced primer in that CZ - never in over 6,500 rounds of with the above loads. The CZ's are known for fairly large pin holes.

; My standard CZ Hornet with i's .223 groove diameter, pruduced 3,340fps with 40gr. bullets and 14.3gr. Lil'Gun- RP brass, an pistol primer, crimped SD's high teens.

; With the Horany 45gr., velocties, same primers, crimped, with 13.8gr. gave 3,200fps average.

: Note - these loads are only for the CZ's and Ruger's.

; We also went to 13.3gr. W296 for similar velocities in the CZ and Ruger bolt guns. No adversse pressure signs.

: Hornet brass amazingly weak in the pockets, if pressures of the above loads were too high, ithe brass wouldn't take 14 loadings of this load then stand re-forming to blown out .17AH's. Soime now have had their second loading as .17AH, all without annealing, and still no case losses. This is with RP brass and I don't know if WW will take the guff.

heres my take on lilgun. Ive found it very accurate in the 3220 and 32mag but it needs pressure to work and reduced loads shot like crap. Its a narrow range powder like 110 and if you find its sweet spot does well but its also differnt then 110 as its not near as forgiving. It goes from mild to wild in pressure like blue dot does. In the 32s ive found my two favorite powders for heavy bullets are 4227 and aa9 they both give good accuracy and velocity and work in a wider range of pressures.
