So today was the first day I got out to shoot my new Winchester BPCR 45-70 at the range. I loaded up some IMR4198 under a 400g and 405 grain cast bullet that I cast myself and some 405 grain Cast Precision bullets.
At 100 yards the rifle was shooting 2" groups with all three bullets, but the POI varied wildly.
I then went out to 200 yards and didn't have enough "UP" on the Burris scope to hit the paper. I had made a one piece mount for this rifle so I loosened the rear of the mount and shoved a flattened 22RF case under it and tightened it back down. Now I had plenty of UP.
My milling machine will rectify this issue this afternoon. I'll put 30 minutes of "slant" into it. Think this will be enough to get out to 500 yds with those 405 g bullets. Or should I be shooting heavier boolets?
At 200 yds the rifle was shooting 5" groups...."This ain't my 6BR!". And once again the POI was in three very different areas on the target board.
Out to 300 yards and the groups held at 5".....Strange?
Ran out of time and cartridges for 500 yards.
Tomorrow I'll return with a few different loads of smokeless and a few with BP.....
I had a Shiloh Sharps a few years back and just never got comfortable shooting that rifle. It was much lighter than this 1885 and kicked like a mule. This rifle is a ***** cat to shoot. Trigger needs a bit of love, but other than that is behaves itself nicely at the bench.
I can tell that this is going to be fun!
