Went out today in 90 degree heat - muggy as all get out, and played with our moose guns - 5 hours worth - man is my neck sore!
Anyway I tried a bit of an experiment - loaded 2 rounds of TTSX in Browning A-bolt and 2 rounds of Nosler Partitions in a Win 70 - both 300wm.
My son and I shot about 40 rounds ea throughout the day and kept feeding a fresh round in leaving the 2 in the magazine to take a pounding.
The Nosler's ( 200 gn ) looked liked the end of a toilet plunger at days end - flatter than grandma's - well you know what - but crimp held them without any slipping into case deeper. I shot them and both went about 1" high at 100 vs their litter mates.
The TTSX came out looking much better - one had a slightly dented plastic tip - the other no dent but did go from 3.34 OAL to 3.22 - so it slipped deeper into the case some. The dented one shot right in there with the others, didn't get to shoot the shortened one as I wanted to measure it back home.
So, my conclusion - when I see one in my pocket while out hunting that has taken a couple smacks - it likely would not affect a 100 yard shot at a critter of any size...
Perhaps a little more crimp on the TTSX is needed and then they would have a +1 advantage due to the plastic tip resisting damage from recoil when in the magazine...
