Should I get a 7mm backcountry?

[grfox92]

A guy at work was talking about his today and said each box of ammo he has opened he has had to rezero the rifle but isn’t getting different speeds on his chronograph. Says the poi has been up to 6” different from box to box. Something seems very weird to me but I didn’t dig.

Are they all from the same lot?

All I know is that he bought them all at the same time I assumed they were.

Do you want a 16” rifle that can shoot 2900-3050 fps ?
I bought the cheapest savage rifle I could find chambered in 7bc , threw a Hyperion K on it and the only issues I’ve had have been with the 155 grain ammo . Every few rounds the bolt lift is heavy .
Every factory load has been sub moa , it doesn’t kick any more than a 7prc , and isn’t that much louder with the exact same silencer . I shot the BC and then my buddies 22” prc side by side . We got nearly identical speeds , recoil was nearly identical . Other than the reloading I don’t see any real downsides

7mm BC is a hard pass for me.

If I wanted a 7mm (and yes I am a reloader) I’d go for a 280 AI.

Good to hear someone with actual real world experience vs a lot of opinions on what they THINK it will be that I see a lot with this round (and some in this thread)

I’m not a BC fanboy but love the idea of a 16” barrel suppressed going 2900fps so I have one sitting in my living room waiting on a scope to try out.

Since you reload and are eyeing a 7mm, seems like the 7PRC, 7SAUM, 280AI, or 284WIN in a 20” is the best route.

I have a 20” 7PRC and if I had it to do again, I’d go 7SAUM for the reduced recoil and same basic effective range given my own shooting limitations.

If I had a full reloading setup and plenty of time to develop loads, I might opt for a hot 7mm08 or the 284WIN.

I’m with most others that 7BC isnt the right answer for now. Remember Etronx from Remington?

In 280AI, I have had or have a 20, 22, and 24 barrel. The 20" barrel 280AI could not come close to the promised 20" 7 BC velocities.

I have settled on the 22" barrel as a fair compromise but I still gave up over 100 fps out of two factory loads vs a 24" box velocities. For some reason, I got 2,600fps from a certain box of factory ammo. (i did not include their name because they took it back for testing to see if they could replicate the issue).

For people who want that velocity (whether they need it or not is their decision) out of a short barrel with a 7mm bullet, the 7 BC is the only option.

Freel saying 7 of the 8 he’s been exposed to had heavy bolt lift amongst a smattering of other reports of the same is enough of a sign to me to stay away. Until there’s been more positive outcomes from a lot of folks. I like the idea of it though. Enough that I picked up some sig hybrid brass formed to 6.5 creed to maybe give that a go at higher pressures.

Personally I think it's gonna be a short lived fad for the reasons above, plus a 3 digit barrel life.

Give me a 7-08 or even 7x57 if I must shoot a 7mm

Haha where in the world are you getting a 3 digit barrel life??
