Depending upon what your are shooting them in, and what you want to do with them, 311291 is a great grouper at 100 yards. And 311299 is fine at 200+ yards, IF IT fits your throat. Loads from 16 -17.5 grains of SR4759 or 17 - 19 grains of H4227 have always been good to me. HTH, Ric

In my Rem 700 LTR I use 21.0 grains 4759 with NOE 311299 sized 0.310 and nose sized 0.300.  With the 20" barrel the velocity is 1800 ft/sec and SD of 7 ft/s.  LC 67 NM brass and WLR primer.  I seat the bullet so the front band engages the rifling a little.  15 grains 4756 gives virtually identical velocity and SD.

In .308, I've used most of the bullets you have listed. If your #311299 will actually cast a .311" bullet, I'd go with that one first, cast of ww alloy. Try 5744, H4895, Reloder 7 or SR4759, though not necessarily in that order.  Same bullet and powders for .30-06 and .30-40 Krag also.

beltfed/arnie,

I recommend you go right to page 149 of the newest Lyman Cast Bullet Handbook 4th Edition. Lyman lists loads for your Lyman  #311291 170 gr RNGC. The 170 gr is the best match to standard twist .308 Win. and this bullet has a long bearing area with a short nose that is not a bore rider and doesn't need to be with the long bearing area. You will have maximum accuracy potential when your bullet fit shows ink smeared on chambering on the exposed driving bands. Most modern .308s need .311" diameter bullets to pass the ink fit test.

Lyman recommends AA5744 for best accuracy because the START level to 2,000 fps has the lowest pressure of the recommended powders and 2,000 fps is usually where accuracy is best. Lyman also recommends BHN 15 Lyman #2 alloy for the load level. The load reads:

2.510" OAL recommended by Lyman, However, seating to a .010" engagement of the ogive to the ball seat taper will further enhance starting stability if that fits your magazine.

START AA5744 19.0 gr 1615 fps @ 18,100 psi  MAXIMUM 31.0 gr 2356 psi @ 51,600 psi

Charge reduction software predicts 25.3 gr AA5744 for 2,000 fps with your #311291 in .308 Win. I'd go right there with a test fit checked bullet and expect under 1" @ 50 yards the first 5 shots with a decent rifle.

If you plan hunting with the bullet, consider the inexpensive Forster Large hollow pointing tool bit in a drill press on loaded ammo, it does an excellent job and increases killing power of the round nose by starting expansion on impact very well with #2 alloy that doesn't fragment due to the malleability of #2 with 5% Tin. If you can maintain hunting accuracy to 2150 fps that equals 30-30 load level with humane harvest of Deer to 150 yards.

Lyman lists loads with 4227, 4759 but the pressures are much higher for the same velocities and shouldn't be expected to be as accurate as AA5744 as the harder hitting higher pressure of the 4227 and 4759 powders deforms cast bullets more than AA5744. The AA5744 is also a lot more popular and available.

R. Dupraz,

I'm aware good accuracy can be had with IMR 4227 and cast, particularly at your lower load level of 15-18 grains where the pressure is low. It is not listed by Lyman as most accurate in the OP's application specifically because of it's higher pressure compared to AA5744 at 2,000 fps. It is pointless to argue against a softer start shooting cast bullets better especially at your 16-18 grains where the pressure is low and comparable to AA 5744, they are both terrific at that level. A higher level is where AA5744 pays off in accuracy, and 5744 is a lot more universally available while having a broader range of lower pressure loads for cast bullets. I have used  over 10 pounds of the stuff and my rifles love it with cast bullets.

I started this thread to pick the brains of you folks that have

pursued and had success with 308W caliber rifles with cast bullets

for CBA 100 and 200 yds score and group shooting.

Have  had some experience shooting my 30-06s in my M1941 MC

Sniper rifle and an 03A3

I am going to now be adding the 308 to my CBA TARGET shooting

efforts. 

NEXT: PLEASE, NO PISSING MATCHES IN THE THREAD. We just

don't need that

Have not shot any of the bullets listed. Mine have been linotype, 188 to 214 grains.

29 - 30 gr Varget, IMR 3031, H4895. In 308 Win, roughly 1900 fps.

4759 provided the most consistent accuracy for me. I never tried 4227. 

I hear there are two versions of 5744...older vs. newer. My older version was manufactured 1996. Is there a noticeable difference in performance between old vs. newer.

Arnie,

My Savage in .308 likes an LBT bullet (312-185 50/50 ww/Lino, bumped, sized 0.311") in Lapua cases and CCI 250 primers, 27.0 VV N-135. At a 2011 local CBA match it did a 0.649" 10-round group. It also likes 27.5 of Varget with all other components the same.

Thanks, oldblinddog,

I have some 311466 on the shelf and have been meaning to try them along with

the 311467 in both the 308 and my M1941 MC Sniper rifle(03A1)

Just don't have any Red Dot.  But will try other of my powders. Adding Unique for some

gallery loads.

If you have Unique, use 12.5 grs.

How about comments on bullet alloy,please?

My long time for 30 cal Target is straight Lino.

How about my go-to for almost all other, namely 9+1 WW/Lino ?

thanks again for all the responses. Hope it helps others besides myself

Yes, I did note that Gary and Paul have mentioned alloys.

I use lino for match bullets because I can make them +/- 0.1% in weight quickly with no visual flaws. However, they don't shoot any better, but reject rate is very very low. For me 2% tin and 2% antimony is just as accurate, but my mould throws about 5% rejects.

311466 is hard to beat.  My Husky .30-30 LOVES it.

I mix about 5 lbs of Rotometals hardball with 4.5 lbs 16/1 (ten lb pot) for ~ 93/3.5/3.5 alloy. 99% of the time they are aircooled. The group in my avatar is the 311466 over 13.0 grs Red Dot with this alloy, shot at 50 yards.

Agree with Ric on lino for competition bullets, but 99% of the bullets I cast are 1:4 lino-wheelweights, or backstop scrap.

In the .308 Win. or any case of its approximate size, such as the Krag, .303 British or 7.65 Argentine,  18 grs, of 4227 with #311299 shoots well in most rifles.  OK to substitute a lighter bullet like Accurate 31-160H or similar NOE design if they fit your rifle throat.

I've also had good results with 20 grs. of 4198, 24 grs. RL7, 26 grs. 3031 or 30 grs. of 4895, 4064, RL15 or Varget.

My favorite powder for jacketed often works well at a start load with cast of similar weights. Other than that, I have found Lyman's suggested accuracy load to be a good place to start.
I have a large amount of WW alloy from the 80's that seems to work well most times. I may have to add a touch of tin once in a great while.

it has been a long time since i scored wheelweights worth salvaging ... but back then i added about 1 per cent tin by weight ... a better pour .... i just buy tin in sticks from the foundry ... at 1 per cent it goes a long ways ...   i might mention i use 92-6-2 from rotometals for my rare serious spells but i now buy most of my plinking lead from ebay ... kinda like a box of chocolates ... ( g ) ... if you find a quality ebay source, try to stick with that guy .... when your melt pot resembles play-dough, you might not want to order from that source again .  ken
