270wsm twist rate?

Will a 1-10 twist rate be ok for berger 150gr and the 169.5 wildcats when they are available? Or is there a better twist rate? Wonder if i wanted to throw in a 140gr accubond, how would that work out?

The 10 twist will work great with 150 and 140 grain bullets, some may be better than others as usual. I know some have shot the 169.5 out of a 10 twist and it did fine but I also know the 1-8 is popular for it. E-mail Paul and ask him, he's good about getting back to you when he can.
As soon as I have them in my hot little hands I'll know, I have guns or barrels lined up with 11,10 and 9 twist barrels and may get an 8 coming soon for the Matrix VLD. Some times you just have to let them fly and see how it works

+1 on the 140-150's. For the wildcats, I would definitely go tighter....Rich

So if i went 1-9 would that still shoot 140 150s ok? My thinking behind this thread is that i would like to be able to shoot different bullets if possible. But it sounds like i could get a twist that shoots several bullets well, but none exceptionally well, if that makes sense. A give and take type deal.

Yes, it will shoot the lighter bullets just fine. The most important thing is to have enough twist for the longest bullet you are going to shoot. The people that are the most concerned about having the EXACT twist are bench rest guys that are only shooting one bullet. They want just enough twist to stabilize the bullet because over twisting can magnify any flaws in the bullet which decreases accuracy. Bear in mind, they are trying to squeeze out an extra hundredth of an inch. If you are going to shoot a variety of bullets, you ALWAYS go with a twist that will shoot the longest one. Hope this helps....Rich

Re: 270wsm twist rate?

The 270 AM is built with an 8 twist barrel and it shoots up to the 195gr Wildcat and I know guys who shoot 150gr bullets to conserve their Wildcat supply and they shoot very well also. The Matrix Ballistics bullets in a 165 and 175 VLD need a 1-8 twist according to them. Most of the proven Wildcat shooters have 8 twist barrels and the newest bullets coming on line are using an 8 twist also so if that is any indication it's not hard to do the math
