    Trigger control with pistol grip on rifle

    I have a Ruger RPR and it has a pistol grip. It seems like I shoot regular stock, like an HS Precision, better than a chassis rifle. I'm a right handed shooter and normally I shoot with my thumb wrapped around the grip on the left (from behind the rifle). I feel like I'm either gripping too...

    What do you think is the problem here...case head seperation

    I generally FL size and decap in one step. As such I am measuring with the primers in tact to set up the bump. I just deprimed 5 pieces of fired, unsized brass. I took measurements with the primer in and with it removed and on all 5 the measurement was exactly the same. As you can see in the...

    What do you think is the problem here...case head seperation

    At least you know. I measured with the precision mic and it was pretty dead on with the Hornady gauge.

    What do you think is the problem here...case head seperation

    Appreciate the feedback and suggestions. The only thing I can contribute this to is the expander ball being a little loose adding additional stress on the upstroke or a slightly incorrect measurement on the Hornady gauge. Solution: I picked up an RCBS precision mic for 6.5, a universal decapping...

    The ring is obvious but I have a hard time detecting anything with a paper clip. Maybe sharpening it to a point would help.

    Unfired brass - .464 Fired - .469 Sized .466 Not isolated I was starting see rings around other brass. But I'll cut one tomorrow my Dremel is at my work.

    What do you think is the problem here...case head seperation

    The brass stretches from unfired to fired ( base to datum) .005, im only bumping the shoulder back .002 AFTER FIRING when I FL size. I'm not bumping the shoulder back from unfired brass. I was saying 1x fired, unsized brass chambers fine. Thus on this next batch on the first firing I'm not...

    What do you think is the problem here...case head seperation

    thats a possibility. I'm tossing the rest of the 2x fired brass and will test the next batch to see if they stretch further beyond the first firing. I think I'll just run a mandrel expander through after the first firing and not touch the shoulder at all since they chamber fine

    What do you think is the problem here...case head seperation

    I checked my notes and Hornady was recommending using the .375 insert. I get different number but the same net result. An unfired case is 1.532.5 and fired is 1.537.5 same .005 stretch when fired. The real question is how much setback is too much?

    What do you think is the problem here...case head seperation

    I'll check when I get home later. It's possible that I'm using the wrong comparator, but with the same one I get 1.551 with factory ammo...maybe thats the issue.

    What do you think is the problem here...case head seperation

    To answer questions: 1.) I'm a tumbler kinda guy - stainless gets everything too clean. I generally don't lube necks because I don't have to. 2.) I'm using the Hornady headspace gauge to measure the setback in the neck. Again only .002. Fired case from base to datum come in at 1.556, I set back...

    Is that Hornady brass? I'm about to order the Redding die and the resident pro on another forum said I should start with the .286 giving me the same neck tension I have now.

    What do you think is the problem here...case head seperation

    This was the 3rd firing on the brass. I just mentioned I'm using the same technique I've used to load 2500+ rounds in my .308 without issue. The .308 has 5 loads on it with zero issues. I'm using the Hornady headspace gauge. I prefer the RCBS precision mic that I use for other calibers but...

    What do you think is the problem here...case head seperation

    I scrubbed the barrel recently removing copper to ensure accurate results when testing seating depth today. Only thing I can think is brass is hardened. Maybe I need to anneal every other firing.

    What do you think is the problem here...case head seperation

    So I had this happen today on 3x fired Hornady brass and it's unsettling. Most of my rifle reloading has been for .308 where I used standard dies RCBS dies. I never turned necks, used an expander ball, and FL sized only bumping the shoulder back .002. I had 500 pieces of LC LR brass that was...
