I hunt with the 115 BT w/H1000 powder, 215 GM primer. They run around 3450+
fps. I have taken antelope, deer, and caribou with bullet and have not had any performance issues. All shot taken were between 200 to 450 yards. I had expected excessive damage but never had with the 115 grainer.
Understand the dreaming part, I have 2 257's one a Lazermark the other a Lhtwgt.
I would try the 115g btip myself. High BC, accurate, and will hold up well. I shot the same bullet at 3200fps out of my 25-06 and killed quite a few bucks past 400 yards, up to 600 yards, and 2 black bears past 400 yards with it. That 115g btip is quite the little killer. Might try the 110g AB if you think the btip wont hold up well enough. I can almost assure you wont have any problems, even with the extra 200fps. I am a shoulder shooter, true and through as I hate tracking. I have yet to recover a 115g btip from any deer shot at any distance or any angle, they simply just dropped like lightning at the shot.
Barnes bullets are a love/hate relationship. I feel theres a lot more on the hate side. They are kinda pain in the ass to get to shoot, its not a problem of them holding up, its a matter of hitting what your aiming at farther then 200 yards away. There not the most accurate bullets, there BC's are a little exaggerated. I have tried the 100g xlc in my old 25-06, it was like buckshot pattern at 100 yards, then I tried the 165g xlc in my dads and uncle 300 win mag. Same thing, more like shotgun patterns then groups. I did what Barnes advised and started with a squeaky clean barrel and trying .050" from the lands. This is just my take on barnes bulles. I am a Nosler fan, I love the btips and AB"s. Not much of a partition guy. More into accurate bullets with higher BC's for longer shots.
I only have tried them in the 7STW and they are awesome in that rifle. (Accumark).
I was hoping to get some data from your post. I've just gotten so use to that 115 BT in those 257 rifles I'm not in any hurray to change. They both shoot well under 1" at 200 yards for me. (3 shot goups)
The only 100 grainer I've shot and taken game with is the 100 sierra w/RL-22.
well I have two boxes of them so I guess as soon as I get the rifle back I'll find out. I'm a nosler fan myself but ever where I turned in the last year all I have heard is how well they do so I have 100 to make shoot or give away. When I bought this rifle it was a 7mm rem. mag an the bullets I put with this gun were the 140 BT....Man what a mess on these east coast whitetails this bullet made. buckle their knees, They look like some drunk coming out of a bar after happy hour.
