28.5 varget/105 amax, 2850 mv, in 26" pac-nor 3 groove in a Ruger #1 custom.
double lunged, with exit, deer stumbled 25 yds before dropping
Range LRF 400 yds.
I plan to use more in my next 6BR, but also will use plenty 95 BTs, perhaps Sierras 85 BTHP,seen it kill deer very quickly in 243 to 300 yds), and also the 85 gr barnes X as I dropped a large hog a 240 yds DRT, with 243 20" mv 3100. My 6BR did 3,000 w/95 BTs so it should equal that short 243 w/85s.
Also dropped a couple of deer with 70 TNTs, one neck shot 45 yds, darned near took head off, DRT. Another lung shot, broadside, dead in 60 yds, range 200yds.
Shot placement first, bullet second. Bullet choice can dictate shot placement choice, or shoot/no shoot during given situation.
A 95 BT will expand and hold speed downrange, but still hold together and penetrate from hard angles, the 105 amax will expand rapidly so close range and bad angles may be 'no-go' but I even head shot a 40 yd doe a couple of years ago, broadside but I had a standing deer facing me so it was lights out, no chance of any following a trail that evening.
6BR in my mind can nearly duplicate killing effectiveness of a 243 to 400 yds w/good bullets and placement.
Swifts should be good bullets, never used, partitions penetrate, but also leave narrower wound channels and I like more expansion/wider wound channels myself. IF using a PT, I'd go with 85 or 95, latter first. Said to be more accurate than 100. Standard cup/core will do in a 100gr in a pinch but again see the top of post for my choice deer bullets in 6mm.
Good hunting.
