Trying to decide between sierra 100 gr gk's and 105 gr speer spitzers in my 6mm-06. Both shoot well with imr4831 and shots could be 300+ yds. I've got a couple boxes of both. I've had great luck with gk's in my .243. Anybody tried speer's on deer, that is the unknown here for me? Does anybody think5 grains will make a differerence at 300-400 yds?
I just put up 2 tripods and some long shots are likely.
It's NOT the 5 grains you have to worry about... They are two different brands of bullet, and are made differently inside... I mean the jackets are different so they will not perforn the same on impact.
Too many people worry about the weight of a bullet, when instead it's the "construction" of the bullet that counts!
I've shot both of those bullets many years ago in my .243, and went to 100 grain Nosler partitions because they easily out performed both of them on deer.
