275 TSX and bullet creep
Posted: Mon Jun 08, 2020 8:47 am
First post here but have been lurking for a while. I’ve read a lot of info and I thought I had a good grasp on things. I went to load up my first samples for load development and ran into some issues with the crimp. I know that’s a recurring problem, but here’s what I did.
18” 1:24 barrel (AR)
Hornady once fired brass, Hornady dies
275 TSX
Sized but did not expand the case
Seated to 2.335”, will window the mag soon
When Charging the rifle, the bolt slamming home and sudden stop caused the bullet to creep forward to about 2.345-2.35”. I taper crimped down to about .472” to try to get a little more tension but it seemed to not really affect the amount of creep.
I’m not sure how much this amount of creep will affect accuracy. I plan to work up the load and then delve into any effect that the creeping might have on my groupings. Any thoughts?
Glad to be here!
