Good point TATELAW. I'd not thought about the twist of the barrel in the OP's query.
I'd not mind eventually trying the 62 TTSX in a 1:8, but I don't think they are going to be necessary, given my purposes. I've not seen a 1:14 that will shoot 53 TSX accurately-- tried in at least 3 guns: a 22-250, a 223, and a 221 FB. Maybe a 1:12 would do it. The 50 TTSX looks interesting for a slow-twist.
I plan on hunting deer/antelope with the 1:8 223. Here at the fire, I keep hearing that the various 55gr PSP do as well for meat deer as the various Barnes. And I hear good things about the 50 V-max too. I know the 55 V-max will punch through silhouette iron at 100 when started at 3500 in a 1:14. Seems "adequate" for critters through the ribs.
Chesterwy, what is your purpose with said 62gr TTSX in your 77?
I know there are guys shooting this bullet and others like it around here somewhere...
