Great analysis. Thanks for putting this together.
I do not feel it would be any different at all. I have chambered two of the same brand of barrel with the same reamer before and got different results. My experiences are outlined in the article. There will be fast barrels and there will be slow barrels. Some do not want to admit it when their favorite cartridge gets a fast barrel and some don't want their friends to know when their pet cartridge gets a slow barrel. My latest 30 Nosler hits pressure at the fastest speeds of all four of my 30 nosler but there is no accuracy up there and the accuracy node is at the slowest speed of all four of my 30 Noslers. That is just how it works. I would personally always choose the highest case capacity that meets your needs. For me that is OAL under 3.75" with a .532 bolt face.Ryan F, do you believe the review would be any different if all 3 rifles were the same build / set up? In other words how much of the variance, do you feel, was rifle vs caliber? Or does that even matter. ??
Great postMaybe it stems from fond memories of our fathers or grandfathers pulling the ol' 30-06 out of the cabinet with the faint aroma of Hoppe's No. 9 or from reading too many Jack O'Connor stories. Maybe it's another reason altogether. It seems as if most of us have a very strong opinion of what the best cartridge is. Over the next several months I will be testing an old warrior along side two of the newest and hottest 30 caliber cartridges. I will be testing the 300 Winchester Magnum, the 30 Nosler, and the new 300 PRC. The plan is to have three 26" barrels, using H1000, and Berger 215s to see how they compare. I will also be testing a few select factory ammo offerings in each. Will we have a clear winner? I guess we will see. Stay tuned.

I’ve enjoyed reading this post and the comparison. Was the PRC the only 9 twist barrel, maybe I missed the twist of the other two barrels. I have never had a .30 cal with anything faster than a 1-10” twist barrel and I don’t know why the push to speed up the twist rate. Was the PRC a proof research barrel? Do you think the twist rate was the cause of the poor accuracy?
You can typically count on 20-25 FPS per inch. The suppressor would give a little back.
