The 105's are good, but since killing a few with our LR rifles and 115gr DTAC's I'm having a 1 in 7.5in twist barrel screwed on a Model 7. The 115's have performed very well so far.
What round/speed? Thanks.
OP - I would use above recommendations esp. on longer shots. Anything up to 400 or so yards a 95 BT will handle fine, depending on what round it can do the job further somewhat, but the 105s take over as the range grows and you have less worry about bullets coming apart as the slow down a bit.
FWIW - I vaporized an amax on a direct spine hit at 200 yds, but at 400 double lunged, it gave a golf ball sized exit. Only managed to go about 25 yds, but struggled to stay on it's feet after hit.
The 95 BT is my fav all around, as most of my shots are not extreme ranges. Next, I plan to try some 80 TTSX. They are not what you want for LR shots as they lose momentum faster and are 'harder' so may not expand great. But since most of my killing is done under 200 vs. over 400 it's not an issue for me.
I have had some 95 BTs do .2 - .3 moa in both 6BR 10 twist and 243 9t. Sure they will also do well as an option in your 243/8t if you have some hunting done up close and want to punch shoulders. I busted/exited said shot last yr at 100 yds.
