Re: Nosler Custom Comp .308 190gr
Comparing Barnes solid copper bullets to jacketed bullets is like apples and oranges.
Where as Barnes are solid copper bullets a traditional bullet is made of a copper jacket and lead/lead alloy core.
Jacket design defines a lot about how a hunting bullet will perform, ie. expansion, weight retention, penetration. When developing a hunting bullet for large game you are looking for a bullet that will enter then expand after entrance and retain a large chunk to penetrate through bone and hard tissue. Varmint bullets are similar to competition bullets as they have a thinner jacket but are meant to expand and fragment as soon as hitting a target.
Custom Comp bullets are pretty much copies of SMK's and they have thinner copper jackets with little taper, compared to a "hunting" bullet that has a heavy taper in the jacket.
Will they kill, Yes! I have blown the insides out of deer with 30-175 SMK's
Are they good for large game animals, NO! These bullets will not hold together like a traditional hunting bullet.Shooting a large game animal with them with a thick hide, heavy bones, and large body cavity could result in several wounded animals or multiple follow-up shots to kill.
As for twist anything 1x12" or faster will shoot them well. PS their are plenty of good hunting bullets out their that will do much better than the Custom Comps, but if you want to try them give them a whirl.
