Went out after work today with the latest batch of reloads. At 45 gr lilgun, 2.115 oal, there's still space in the cartridge, no violent recoil, and considerably less bolt face imprinting than the last batch @ 41gr. The stouter load must stick the brass to the chamber better for less rearward thrust?? Almost no sooting. The action fed flawlessly from my unmodified sig mag, with a nice tight pile of brass. I used the modified fcd with slightly narrowed crimping lips, then taper crimped to remove the slight bell from the expander and fcd crimp. I'd have some chrony numbers for you guys but.............. .....took out the chrono on the first shot with a low blow fmj. Dont ask how or why, i'll do better in the future, i promise
I did however get some good pics, and the 3/8 plate is totally busted!!!
fmjs punched holes in 3/8x6 flat bar from about 50 yards, holes mic around .700, more expansion than expected.
This is one mean load, but do your own research, be responsible, beware, this is my experience, but yours could be different.
thanks
