245 grain Berger in 300 Win Mag.

[Shane Lindsey]

That was my hope.
Berger gave velocities (quickload) that topped out at 2745 or so with 87.7 gr. I am above that with 83.5gr N570, but ADG brass doesn't like to operate much higher. Concerned going any higher will trash the brass early. Primer pockets are a little loose on some of them already on two firings.

Reviving this. Anymore info on these is a 300 WM?

I know it's not a 300 wm but I'm using the 245's in a 300 prc with retumbo and I'm getting 2808 fps and is insanely accurate.

Not a 300 WM but you should easily see better velocities than you posted with your RUM.

I am shooting a 300 NMI with a 24.5" barrel and I was getting 2866 with a 3 grain reduced load since I was jamming into the land for fireforming.

My last go around with the 245 gr was in a 26" carbon 300 Rum , nv570 I settled at 3010 ft.per.sec.

With the RUM I got to 2929 FPS with it, but it trashed my cases after three firings.

I figured I could get close to the 300 PRC.

Its just what handloaders have been doing with the WM for years.

26" barrel?

Yes you bet it is 26".
I know 2808 fps Doesn't sound that impressive to a lot of people but this thing is a hammer a long ways out there.
I've had it to 2000 yards with ease.
I reached almost 2900 fps but it opened up
Groups. The sweet spot was from 2700-2830 fps in this 1-8 twist prc.

My last 300 WM did 2956 FPS with a 215 Berger. Was hard on brass though. Probably wouldn't run it that high for long.
At 2700 FPS the 245 is right there with it at 1000 yards. Beyond that it just gets better.
