375 EnABELR Build

[SheepShapeAK]

Now that the reamer is headed to the house I figured I would start this thread. This will be a ground squirrel hunting rig, launching the badlands 365 and 390 grain Super Bulldozer-2's.

Approaching a year next month on my suppressor. So much for 90'day e-forms.

Second barrel is on the way to the house, and reloading components and dies are sitting in the office.


Cartridge: 375 EnABELR
Action: 1.6" Stiller TAC Driver, .640" bolt face, 40 MOA rail.
Barrel: 30" 1:8 twist K&P 1.35" straight contour
Trigger: Triggertech Diamond
Scope:
Chassis: Mirage ULR
Bipod: Still undecided. Maybe the elite iron revolution.
Suppressor: Elite Iron 375 Asset

You sure you have enough horsepower for ground squirrels?

You're right, I should probably consider a 416 Colossus next.

Any kinda reloading data on the 390gr bullets yet.

Not that I've seen. I'm going to just use the AB data they had posted for the 402's as a reference.

And I thought using a Rem 700 in 25-06 was a bit much for ground squirrels.

I shoot the 350gr sierra match kings with 125grs of retumbo right now. But what to go heavier for competitions.

Yeah, I was hearing they were getting good results with Retumbo, but it's nonexistent right now. Don't want to burn up what I have doing load development and then I can't find it.

I'm currently running 379gr Berger solids with 132.2gr of VV 24N41 and getting 3035fps from 32" barrel. I am very impressed with this round.

It seems to be pretty impressive……..what is the anticipated velocities with your bullets listed! memtb

If I can get 2850 fps with the 390's I'll be happy. I expect the 365's will be over 3000 fps.

I've got a few powders I'll be testing out. Chase Stroud said they're getting good results with Retumbo, so I'll try some powders close to that on the burn rate chart. I've got a bunch of H50BMG to test with, as well as some faster stuff.

Wow….pretty impressive velocities for a bullet of that weight! memtb

This is from AB's testing. They considered these "mild" loads.

I love my .375's, but that's a bit more than I think I can enjoy from my 9# hunting rifle! memtb
