i have used the 120 b.t in 3 rifles, a 7-08 classic r.700,a custom m-77 in 280 and a m721 7rem. mag. even in the longer thorated ones it is the most accurate bullet ive seen. the 7 mag i just tested a first 3 shot group of .25. thought it was mistake. 2 more were half in or under. my 7-08 when i am doing well is a half in for 5 with max load of varget. great accuracy. my friends son used the 7 mag for a 14in. antelope at 400 yds. passthru as to be expected at reduced velocity. a little concerned about bullet integrity on larger animals and closer ranges. my exp. it is the most acc. bullet ive used in the .284 dia. my wife has a mdl. 7 which i plan to try next.
