I'm 68 and have been reloading for over 47 years and I do not anneal or shoot in competition.
Two weeks ago I went to resize some well used Federal 30-30 cases I bought in 1982 and the necks started to crack. :frusty:
The average deer in Pennsylvania is shot at 40 yards and when you are standing on your hind legs shooting at a running deer neck tension is the last thing on your mind.
I also prefer to go to the range when no one else is there, that way when I leave the range I know I was the best shot that day. :first:
And at the Whidden die website they sell expander kits with five expanders from bullet diameter to .004 under bullet diameter, to control neck tension.
I do not need the Whidden expander kit for my 30-30 because after the necks crack on my 37 year old 30-30 cases I just buy new brass. :smile-new:
The last time I shot at a deer it was going full warp speed across a open field at over 100 yards.
All the bullets kicked up dirt behind the running deer so I guess the hard brass in my case necks gripped the bullet too tight and slowed them down. :sorrow:
