@Curtism 1234Imo, dont be too picky. Ammo that shoots 1.5" is just as good as ammo that shoots 1". I personally wouldn't get hung up on finding the Aframes. Grab 4 boxes of 180gr federal bear claw or nosler partion and I'm sure they will be more than adequate
Stock bedding and free-floating can make a huge difference imho. I once took a crappy rifle with a crappy stock, which couldn't hit an elephant if you were standing in front of it and by working on the wood to metal fit turned it into half-as-good-as a target rifle. The second thing I found was the trigger. There really is a difference between an average trigger and an Anchutz match. There are more ways to tune a rifle that just choosing ammunition.For a 06 I would stick with a 180-190 grain bullet for the max weight. Yes you can find them up to 220 and a little bit heaver but you will find that performance drops as the bullets get heaver.
For a plains game hunt 165 grain bullets would work quite well. I also agree on grouping, some rifles will become tack drivers with ammo that they like but then there are rifles such as the Ruger #1 that will never drive tacks. Some will but it takes a lot of experimenting to find the load that will do it. Even a extra 1/2 lb of torque on the for-end screw will throw the group off.
Yes it will! Several years ago a friend of mine was headed to S.A. for a plains game hunt and for his '06 he bought 4 boxes of Winchester premium black talon ammo. He called me the day before his flight and said the best it would do was 4" groups and asked for some help. With limited time I took some of my handloads using 180gr Hornady interlocks over and we shot them in his rifle. The result was nice little cloverleaf groups ( 3/4" ). I loaded 80 rounds for him and he used it to take 14 animals and lost none. They work very well!This is going to be near heresy on here, but I have a rifle that shoots American Whitetail factory ammo extremely well, that ammo uses the interlock bullet. I have used it on a fair amount of game with very good results, before the craziness, it was less than a buck a round. If it was all I had, I would use it on a plains game hunt, no problem.
