My 270 was OK with 130 and 150's.

Saw a guy in our deer club kill a nice deer with a 110g Sierra, tried those and got very small groups

top end loads of R#17 and Win 760 both shot sub 1/2" groups at 3300. Shot a few deer but did not get complete penetration on one shot, so went to the 110g TTSX, groups got smaller, and brother, do these bullets drop deer! WOW!@
