Re: What makes a big game cartridge also a good varmit cartridge?
I would say a 6.5mm with 140gr class bullets for big game and the lighter 100gr size pills for varmints. The mid size 7mm would be a good choice also.
The 6.5-284 would probably kill deer efectivly out to 1000yds as well as varmints and with the same bullet !! If I were shooting say Elk that I'd choose a bit stronger bullet like a partition. I've killed a deer with a 308 at 618yds with a factory loaded 175gr Sierra Match King bullet and the 6.5-284 kicks it butt balsiticaly with a 140gr A-max .
Say a 280 Ackley improved shooting a 160gr accubond would cleanly kill Elk to 500yds if the conditions were decient , loaded with a 150gor Balistic tip I'd say it could be a 800-900yd deer gun , load it with some 120gr Vmax and it would be very explosive on smaller "varmint" out to at least 500-600yds and still kill worthy out to close to a grand. This combo burns a little over 60grs of powder , barrel life is deciantly long , I'd say close to 2000 maybe more.
