Chuck,

Thanks!

No practicing just experimenting with loads. Read on the Shiloh forum that Hornady 405 Winch. cases work better for PP than greasers. Something to do with the case mouth thickness. Supposedly they are too thick for greasers. So since I got the rifle in early 2010 I’ve been trying greasers with marginal success. 

Then in late 2019 I started messing with PP. I bought (50) slugs, paper and a template from Buffalo Arms. Shooting those convinced me to buy my own mold. But with coaching from a few guys on the Shilo forum, I ordered a dual diameter mold from Steve Brooks.

Additionally, all previous loads were 68.0 grains of either Swiss and Old E 1 1/2. Just recently increased it to 70.0 grains of Old E 1 1/2. And changing to the large pistol primers seems to have helped.

Been playing with where the patch starts on the ogive. Looks like the location I’m using now will work.

A test is coming up tomorrow. A Scheutzen match at a club ab hour north of me. Unless the round count changes, it will be (40) rounds off the bench, 200-yards, iron sights.


This will be the fourth year I’ve been going to this match. I will have past greaser results to compare to what happens tomorrow with PP.

Chuck,   The match went well. Not so much in the results but in a lesson learned.   The year after I got the Sharps, maybe 2011, at the March gun show, an old friend who I shot many handgun silhouette matches with, stopped by the CBA table. We got to talking iron sights on our BPC rifles and he told me something about the front aperture. It was his opinion that many people use too small of an opening on the front aperture. He suggested dividing things into thirds. The area on each side of the target is 1/3 of the area seen through the aperture and the width of the target is the remaining third.   I got to thinking about this as I was driving home from the Saturday match. I think I have too small of an opening in the front aperture, for the Scheutzen target. My eyes try too hard to get everything concentric….rear sight, front sight and target bull. In doing that the rifle is being unconsciously moved ever so slightly.   The 200-yard iron sight Scheutzen red bull is 12” diameter. To test the theory, we need a 36” diameter circle at the 200-yard target location, look through the sights, exchanging the front aperture until the aperture opening and the 36” diameter test circle share the same outer edge.   My reasoning…..Three days before the match, I shot the turkey target @ 200-yards and 7 of the 10 rounds made a group of 4 ½”. When looking through the sights, the turkey is a fairly small image. The width of the turkey is 7". This 200-yard target size is meant to closely replicate what is seen through the sights when looking at an NRA steel turkey at 385-meters, reduced in size for use at 200-yards.   Looks like I have the right size aperture for the turkey but now I need to find the right size for the Scheutzen bull. I cannot expect to use the same aperture for both. The loads on both days were the same. The current front aperture is 0.106”. The largest one I have is 0.127”. The aperture set ranges between 0.060” to 0.127”. To experiment, I’ll start with the largest.   Tom

If you shot ASSRA targets,  the Iron sight targets are Black one side Red the other? have some in the shop will have to look again

I used a .120 front aperture for Sil shooting, and one big enough to see white around the black, for paper targets

Tried to shoot the postal match today after the 200 yd GH match the club has...old eyes and pain means I'm done shooting .40caliber and above, the PD is making things harder to do..

Yes, the ASSRA targets are black one side and red on the reverse side. Everyone at the matches I’ve been to, prefer the red for better locating of hits through the spotting scope from the bench.

 

Somewhere I saw different front sight aperture inserts for the various odd shapes of the silhouette targets.

This is what I noted above, in graphic form.

I have seen the inserts, looked thru the sight with them, not impressed, not all the animals are cut the same, mostly done with a torch, vary a bit in outline

to my knowledge, none that shot with me used them

I shot mostly Ridgway, Mcdonald PA, Raton

I should know, whose front sight are you using? I like the lollypop inserts Ron Snover made, I also have Baldwin front sights, and the annulare ring is not thick enough for me, it disappears after about 5 seconds looking thru it, but as I understand it , it's my problem, not the sight

would 1/3 be a lot for you eye to center? alto Harold Knisely set the Ram record with no insert in a rain storm at the Pennsylvania State Championship, IIRC 1998, whatever works

Yes, my rear sight is a Hoke and the front a Baldwin. 

This is what I like about BPCR shooting. So many twists and turns in the road and ALWAYS something new to learn! Especially at matches.

There is a lot to what you say about the ring disappearing. You can only look through these sights so long and then you need to look away. Timing is everything.

Don't know if 1/3 will work but I plan to "see" what it "looks" like.
