Custom Rifle Help: 7mm Cartridge Decision and BDL choice

[Dirtrax]

One of the 7mm-300wm's in any of its variations. I'm easily pushing Berger 168's at 3200 FPS without unreasonable pressure with a 28" barrel. Specifically, mine is a 7mm Practical using an off the shelf Manson reamer.

 

[RH300UM]

200 yards. 5 shots

But if you want to go the next level there is the 7RBH
195 Berger's at 3250 fps and laser like accuracy
Of course it takes a .585 bolt face but it's on the top for a 10# hunting rig with the accuracy I have needed
But Travis @ RBROS Rifles is the magic maker for this and "all" my Rifles!

That's a little scary in a good way...

Assuming 6000 ft alt, 50 deg F, 3250fps would give Elk energy out to 1420yrds yielding 1509fr lbs. Of course that's on paper, but that's a lot of fire power. The chambers likely go in 1000-1500 rounds but hey barrels are wear items. Hopefully you could quickly find a powder combo that shot consistent and accurate. At 1420 yards, assuming an elks kill zone is 24 inches, a 1 MOA rifle would suffice as 1 MOA at that distance is about 14.87 in. Anything tighter would be of course even better. I say build it and put the biggest Terminator brake on it and you're ready for some ELR fun.

Cartridge choice in the 7mm's has been my struggle too. I was going to build a 280 AI because I have a couple of rifles that need new barrels. but if I sell off some stuff, or trade I'll go a 7mm RM. 28 Nosler works too if you have the money to rebarrel often. But since I also like to shoot a lot a 7mm RM makes the most sense. Brass is relatively easy to find. 175gr-180gr class bullets is what I'll probably stick to. And there's tons of load data out there. That's my choice but a 7mm-300 WM or 28 Nosler works too.

Def get adg brass for your 7mag if you go that route. I loaded some for my brother's rifle, it's excellent.

Thanks for the tip. On the cheap so at a buck and a quarter it's a bit too rich for me. But thanks for the heads up.

Those look great. What powder are you using?
