Greetings,

Here are results of my first go using a Springfield Model 1873 Trapdoor 45-70.

Bullet:   420 grain flat nosed, not sized

Powder:  55 grains Goex FFG

Primer:   CCI 250

Case:   WW

Lube:   SPG pan lubed

Distance/target: 100 yard/ T-4

Score:   First Set ("Record") Target 1      1xX, 1x10, 1x7, 1x6, 1x5      38 1-X

                                              Target 2      2x9, 1x8, 2x7                        40 0-X

                                                                                   Total  78 1-X  "Record Score"

           Second Set                Target 3       1xX, 1x9,2x8, 1x7                 39 1-X

                                              Target 4        1xX, 1x9, 2x8, 1x7               42  1-X

                                                                                    Total  81  2-X

Comments:  Shot a different bullet than I used for the groundhog, I think I need to use the Lee 405 grain Hollow Base bullet for better accuracy.  As that seems to shoot better groups, and a heavier powder charge on this 420 grain bullet seems to work better, I am wondering if the obturation is giving a slightly better group.  Anyway, here is my first set of targets using targets 1&2 for "Record".  If I get a group worth photographing, I will do so and add them.  Otherwise, two of my targets were "heart of caribou", one was "heart of moose", and one I would need to get out the snowshoes.  The two best groups I swabbed the bore with a wet cloth then used one or two dry patches before the next shot.

200-meters, iron sights. The load data is on the top photo, lowe RH corner. You might have to enlarge it to read it. This is the first try with Old Eynsford 1 1/2 powder. Have tried Swiss 1 1/2, Swiss 2, KIK 2 and various Goex versions. Started out with FC 215M primers, tried FC 150 lg. pistol primers but have recently settled on CCI BR-2.

Now it is time to experiment with load variations. The second photo is the current CBA BPCR target. Best I ever did was 7x10. That high shot to the RH side was an AD! That turkey looks microscopic through the sights compared to the black bull.

Very Nice Turkey target, I found OLDE E to be about 120 fps faster than KIK, same gtanulation

Guess there is going to be competition this year, hopefully you will shoot scope also

Chuck,

Do not yet have a BPCR with a scope on it. Am working on a Rem. Rolling Block that needs a new barrel put on it. I have the barrel (octagon Gr. Mountain 1:12) and the rifle with an original sewer pipe 7mm barrel. Need to buy a reamer and get someone to do the machining, assy. etc.

2018?

Tom

May results: 100 yd scope group- 4/5shot groups 1.359", 1.096", .667", .874"   agg. .999"

                     100 yd scope score- 88

comments: Rifle CPA 32/40 Shilen bbl 14" twist 28" long. Unertl 20X scope. Load: Hoch base pour bullet, 200gr 25:1 mix, SPG lube. Breech seat bulllet, use one case that is scraped between shots. Swiss 1 1/2F powder. Full case of powder, fiber wad .030 with .075 compression. Rem 7 1/2 primer. Rocky Mt. Everlast case with small primer pocket. Two wet patches and one dry patch between shots.  Patches not as wet as normal, and the humidity was 57% .In the summer here in Iowa when it is hot and the humidity is high;90%+ the rifle shoots the best. With the high humidity, and the wet patches it is like a sludge that comes out of the barrel when it is wiped. Case must be scraped immediately or the fouling is like a sludge.

GWarden,  Those are some very good groups!

I have yet to shoot. Still getting snow here. I am going to really bump it up a notch to be competitive.

Good looking turkey target!

Not a big deal but when the CBA does a Postal they use a due date of for example 1 June. This means you shoot your target before 1 June and mail it of for scoring before 1 June. So the first one that I did here was due 1 June target (for me anyway). On Sunday I shot my July and August targets. Have too much going on in non-shooting areas so I shot them in advance of the “due” date.

Same rifle as last time (CSA Model 74) and basic load. While the scores are mediocre there is a difference in the loads used. The one on the left (July) has two 0.060” poly wads in the load. The one on the right (August) has the same two poly wads and a 0.060” veggie wad underneath the poly wads. So I was looking to see if a difference in group size surfaced and it did. This does not mean the addition of the veggie wad is key. What it does indicate is that more compression is needed in the load.

And….the firing pin finally gave out. I tried 3X on a 10th round but it wouldn’t go. When I got home I replaced the pin. There wasn’t much left of it. This is pin #3 since I’ve had it, getting the rifle new in early 2010.

I do plan to try paper patched loads somewhere down the road.

Too bad the photo is upside down!

FWIW

You guys are getting serious on those Turkey's!

We seem to have some decent interest in this in-formal Forum Postal. Maybe this could carry-over to the CBA Postal match 22? It could be worthwhile to remove the need to use X-sticks in #22 if that would encourage more shooters. If the turkey scores go up a little we still have the white center to serve as a tie breaker.

At my range it is challenging to use the 200-meter range. There are concrete benches and a concrete floor that extends out about 20-feet beyond the benches. So to stab X-sticks into the ground I would have to be out in front of anyone shooting from the benches, which ain't going to happen.Sometimes I get there and a few shooters are on the benches so I don't shoot. Letting everyone shoot from the bench might draw in a few of these Forum shooters to try #22 in 2018.

Personally I like the turkey more than a big black bull but could go either way if we wanted to change the targets.

We could consider a rule change for #22 on this for 2018; no X-sticks and change to big black bulls?

The input of our in-formal Forum shooters here would be welcome.

I know you instigated match #22, hoping to keep it like the NRA BPCR, and I have been in since it started, and I thank you for that

IMHO, leave the sticks and the target alone, make it two classes, Iron Sight with NRA rules ( no clicks) and Any Sight ASSRA rules, (any scope 6X only, tube sights, iron sights with diopters and clicks, etc.)  cross sticks any position, bench cross sticks with NO clamps to give the sorry-wobbly condition of cross sticks in the ground create, no rear bag or glove, no grounding or supporting of the butt stock

No wind flags in front of the shooting position, NRA rules allow a flag at the cross sticks

ANY Single Shot rifle, not a bolt action, any cartridge originally loaded with Black powder, 14 pounds max weight, plain base bullets, no Gas Check

Black powder or Pyrodex only, no duplex

I would keep the target one of the animals, if 100yds is only available, maybe a reduced chicken, or the Turkey reduced for 100yds, or the 100yd small bore Pig

just some of my thoughts to maybe get more competitors

Chuck,

Good suggestions!

I cannot find my NRA rule book. What does....Iron Sight with NRA rules ( no clicks)  mean?

Would "originally loaded with BP" allow (today) any powder type, including smokeless, in a chambering that was originally introduced as a BP round?

Thanks!

Tom

I'd agree with the bench top cross sticks. Not because I happen to have a set but because it would give some assurance that I can shoot when I go to the range and not have to try again another day, due to what I described earlier (sharing the line with bench shooters).

If we expand the CBA #22 Postal to have the option of 100-yards and use an animal target, the IHMSA 50-meter handgun/NRA Rifle 200-meter chicken might be too big (bottom of the photo). But the others seen in the photo might be too small, except maybe for the scope category.Maybe the half size Field Pistol pig would be something to consider.

If we are sticking with the animal target theme, we should change the title of the event to BPCR Silhouette for 2018.

FWIW

The no clicks rule applies to scopes also in the NRA BPCR game

no clicks means no definite stops at minute setting ala. Redfield or Lyman target sights or like any of the current internally adjusted scopes..or the old Lyman and Unertl scopes

My MVA scope just has a slder and a clamp like the Iron sights, DZ arms makes scope mounts that are similar to Unertl with no clicks making them legal for the NRA BPCR.

 

Personally I would like to keep it Black Powder, because BPCR means Black Powder Cartridge Rifle, also the reason for 12 1/2 minutes for 10 shots with sighters, if you are going to shoot smokeless then the regular rules should apply, IIRC it is 2 min 15 sec with a 15 sec ready command, no sighters...been awhile since I shot the Offhand Silhouette game

A comment

If the match goes to Smokeless I would probably not shoot it, there are 4-8 pages of CBA matches for Smokeless....Match 22 is the only way for me to keep my hand in the game with Black Powder..if you want to shoot Smokeless, why have a Black Powder rifle at all

These comments are from a person that will officially become a Curmudgeon in Sept this year
