Custom 300 WinMag "Blood Red"

[James Runner]

I went 1:9. It may be considered on the low end but most of our hunting is at 1400' elv. And 1:10 was a hair on the high end according to Berger's twist calculator. Other than lightweight varmint bullets I have never heard of really "over twist". This may be disputed by other more experienced shooters. But up to a Grr, I have seen zero negative effects.

What grain ammo did it like being a 1/9 twist? Or what grain did you go with?

I do have and still have a decent stock of the Berger 215 Hybrid so I went with it. Needless to say I love the performance and didn't need to try anything else. With 26" barrel and a can on the end Velocity Validations at 500yds prove the 3060fps at 2000' elv.

Brass and dies available as well.

How does it feed with the belted cases in those mags

 

[Goldy300]

I have 2 mags. The first one is a Generation 1 PRC mag. I had to do some filing on it to make it feed smooth. The new one is Generation 2 "Magnum" magazine. It has factory chamfers on it and feeds even better. Both are easy now.

I second what Goldy300 says.
I have the second generation "Magnum" magazines with my 300wm. The rounds chamber with ease.

Where do you get these mags?

 

[Goldy300]

I called Hawkins and they pointed me to someone that had 1 in stock.
