Question for THF. I am about to build a custom rifle to shoot Berger's new 195 grain Elite Hunter bullet. We have waited on this bullet for almost 3 years. I am very excited to get this project up and running with these new bullets.

My question is- what caliber should I go with- 7 Rem Mag or 7mm/300 Win Mag (a 300 Win Mag necked down to 7mm)? These are the only 2 calibers to chose from!!!! 7 STW is too long, and a WSM, uh, just no!

Keep these factors in mind:
1- I plan to shoot this rifle for load work up, but plan to sell this rifle once I develop a load for it.
2- I want a magnum round that can push this 195 at a high speed to take advantage of the high BC.
3- I would like to have a rifle to test in 7 Rem Mag to sell 7 Mag ammo with this 195 grain bullet
4- This bullet requires an 8" twist barrel to stabilize, so a 1:9" is only marginally stable.

Estimated speeds-
For the 7 Rem Mag, the 195 should be running about 2850-2900 fps.
For the 7/300 Win Mag, the 195 should be running about 3000-3100 fps.

Specs for the build:

Stiller Predator action
Krieger barrel- .284 CAL SS 5R 1-8" #15 STANDARD PALMA Contour 26"
Timney trigger
20 moa rail
BDL, hinged floor plate bottom metal
stock- undecided, but will be a hunting style stock
Threaded muzzle for brake or suppressor

I'd like this rifle to be geared as a high-end hunting rifle, and not a competition rifle. I am leaning towards the 7mm/300 Win Mag case, because of the higher speeds. 150 to 200 fps increase is a lot of difference in energy on target. Ammo is easily made by running 300 WM brass up into a neck die with the proper size neck bushing, which I already have the dies for.

Now, a penny for your thoughts!!

Like the idea of the 7mm/300 for this bullet but from a business standpoint which will you sell more of 7mm/300 or 7mm Rem Mag?

Pretty much any rifle that will work best with that bullet at this time will have a non factory barrel on it unless I am mistaken most 7mm factory barrels in 7mm are 1:9 or 1:9.25

Plain old 7mm would be best.

Just curious by why no WSM? Lack of brass possibly? I'm currently having a 7 WSM built to shoot the 180gr bergers, but may try out the new 195s

What about 28 nosler to gain some velocity over the 7mm mag and will still have factory brass to buy?

If you want to maximize the gun 7mm/300

If you want to be friendlier to reloaders who can't/won't modify brass 7mm mag

From a hunter standpoint keep it a 7mm and make it easier to sell.

It sounds to me like you'd be gearing this towards more of a speciality market/niche group. I assume 1:8 is not too common in factory rifles because commercially available ammo in 7mm mag does not do too well. Also, if the selling point behind the rifle is it's based around this specific bullet, seems like future buyers have no choice but to reload anyways.

That said, I think you go for the odd ball (7mm/300 win mag) cartridge.

Now when can I come by an pick up my penny?

“We have made 3 kills with the bullets, and they perform extremely well. The animals were llamas, which are normally hard to kill. We took three shots from 10 ft, 500 yards and 1046 yards. All of the bullets expanded and killed immediately. One of the shots was a frontal which flipped the animal over completely!”


10 feet on a llama? Is that even ethical?

Brass availability, somewhat finicky to load for, needs a long action to get the true potential, and if I'm going long action anyway, let's get a bigger case to push it faster. Just never been a WSM fan (except for the 325 and 338 WSM rounds).

I have worked on several 26 Noslers, and about to work on a 28 Nosler. They are similar to a RUM, they are very finicky, and I'm not a RUM fan at all.
