No SAAMI is .188. This barrel is .130. I have another barrel coming for another rifle with a .188 SAAMI chamber. Both chambers have been shooting very very well with factory 147 ammo.Does that rifle have a SAAMI spec chamber?
Has the factory ammo been consistent from box to box (base to ogive, OAL, FPS, etc)? Also, with the .130 FB, are you almost touching the lands?
Hello all, getting ready to build my first custom and I'm confused of witch one to go with. They look similar in ballistics. Any reason to choose one or the other? Components will be mc gamescout with a left hand rem 700 (long or short) with a 26" bartlein #3 barrel. Thanks in advanced. First time posting.
I have just gotten my .264 back and shot it a couple times with ELDs.
It is a Savage with a Shilen 26" 1-7 twist, stainless barrel.
I've some Sierra 150s and Vihtavouri 24N41, Norma 217, H870 and H1000 to try out.
The belt doesn't harm anything as you should headspace on the shoulder, anyway.
If you object to the belt, the PRC is your choice.
The throat was extended .160".
Have fun,
Gene
I had a 6.5 creed and built a custom 264 win mag. The wm is pushing 140gr Berger elites at 3,217fps and shooting in the .2/.3's all day long.
With the same bullet in a prc, I'd guess you'd be lucky to get 3,000fps in the same 26" barrel.
Just depends on what your setup is going to be (detachable mag or bdl), game you'll shoot with it, are you going to reload?
If you reload, I'd look at the 6.5 SAUM as well - 3,100fps easy with same 140 gr bullets and just as accurate as either caliber.
*the good thing is, if it's custom, do whatever you want! Whether it makes sense to anyone else on the caliber choice doesn't matter!
Have fun with it and let us know what you decide!
