7 Backcountry Ballistics Data

[One300wsm]

7 BC vs 7 PRC is not exactly apples to apples… it’s close though.

A 16-inch 7 BC produces more velocity than an 18-inch 7 PRC (maybe even 20-inch…). It does this while having less recoil (odds are you wouldn’t be able to tell a difference).

7 PRC will have significant more factory produced ammo as I doubt manufacturers will produce 7 BC due to the Peak Alloy case that is used.

16” probably so, 18” factory ammo only, 20” not even with factory ammo.

I built a 7 BC on a very lightweight Tikka build with an 18" carbon fiber wrapped barrel. Whole gun is 7 pounds 6 ounces scoped up. So far no issues with all the factory ammo I've tried. It's favorite so far is the 155 gr TAs going 3126. I am going to reload it with 160 gr Barnes LRX at some point and see how it goes. So far, I am loving the gun and has performed very well for me at the range.

Granted semi-custom versus factory could make a huge difference. A colleague of mine picked up a Seekins PH3 in 7 BC and no issues there either, that one is just heavier.

What stock did you use? I'm currently waiting to get my tikka action back machining and nitriding from Unknown and my 16.5" barrel to ship from Proof!

I went with the Peak 44 Blacktooth stock and my barrel is a BSF instead of a Proof

How do you like that BSF barrel? I just put an 18" BSF on my suppressed 300 WM build. It shot lights out when I took it to the range a couple of weeks back. I still need to get it broken in and figure out which ammo it likes. So far it likes 165gr Federal more than the heavier 200gr Federal TA.

Every one I've had has shot lights out with not much break in so I've loved them especially being a little better price than a Proof. I've had some surprisingly long strings of fire with them in 300 WSM and others before seeing some walking from heat. Even had an AR barrel from them and that shot great too.

That's good to hear. I stumbled upon them while reading the specs of the Weatherby 307 Alpine CT. After doing more research and discovering that they have a generous veteran discount, I was sold. I'm sure this won't be my last barrel from them.

I believe a BSF barrel has Weatherbys all time three round group record as well. Just kind of a cool factoid on top of that haha
