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.
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"
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!!
