7mm rem mag short barrel

[Desertguy]

Trying to settle on the right elk gun. I know I’ll get the X Bolt 2 chambered in 7 rem mag, but I’m torn between the SPR 22” or regular 26” barrels. I’ll screw on an 8” can so length is a factor, but I don’t want to sacrifice too much EV and energy. Anyone have data on this caliber in a 22” barrel?

Another recent thread has some info you may be after.

You won't have any issues with twist rate unless you're running a bullet that is already borderline unstable.

Great insights. Thanks for sharing your experience.
This comment in particular is where I'm worried. Per Hammer's website, the 145 hht requires a 1:9.25 twist or faster. I haven't seen any signs of instability with the 1:9.5 and 24" barrel, but I wonder if that would change going shorter.

After research and thinking about the gun model (proprietary action), I'll probably leave the gun alone (why mess with a system that's running flawlessly), preserve what resale value it...

Do you know what bullet you'll be shooting? I get 2705 from a 20" barrel with factory 168gr Berger Hybrids.

I found that thread after I posted lol. It would either be the 168 Bergers or something really close. Twist becomes a factor too since it’s 1:8 on a 22” barrel and 1:9 on the full length

Gotcha. I can tell you that with a 20" barrel and OCL Hydrogen S (7 inch can) direct threaded on, it feels quite long. Manageable for sure, but long. If I had an 8" can on a 26" or even 22" barrel I'd go nuts lol.

I cant imagine using an 8 inch can on a 26 inch barrel, or really even a short OTB can on one. 22 inch barrel with an OTB can is about the longest I could want.

Unless hunting is just posting up in one spot sitting, if that were the case I suppose it matters far less.

What round are you shooting with that setup?

 

[Mac-N-Tweas]

Currently in the same boat, sending off a 26" #2 contour barrel to get cut, crowned, and threaded for cans between 5-7". It's going to be long but will keep you updated once I can chrono 168 ABLRs. Running warm charges of H1000 I don't foresee a huge drop in speed once the can is added but I'm hesitant to cut a 7RM too short. The speed and energy downrange was half the reason I picked the cartridge years ago in the first place. I am leaning towards 23" and something like the nomad ti xc as the best compromise.

That’s what I’m looking to run too. Good speed and knockdown power from long range?

I had my Rem700 in 7mmRem Mag cut back to 22” and threaded. My handload 165gr Sierra TGK go 2890 with Winchester Staball HD. The 165gr Notma Bondstrike does 2875 with the same powder. I am good with the numbers since the accuracy is there.
