300 Win Mag vs 300 PRC

[Guy M]

Had a lot of fun comparing these two great cartridges, one old, one new. They both do about the same thing, but with rather different cases and some other differences as well.

Got scorching velocity with the 180 grain Berger and the 300 Win Mag with Magpro powder. This was in 30 degree weather from a 26" Bergara barrel.

At over 80 grains of powder per cartridge, I went through rather a lot of Magpro coming up with this info. Fun though, I hadn't done much 300 magnum shooting in quite a while.

Regards, Guy

Only true difference is 3.34" COL to 3.6" COL.
You can do this, as I have done for 30 years, with ANY 3.6"/3.7" action with the 300WM, nothing new there.
Been using the A191 reamer for a decade or more, has the correct throat length for 215's to 230's……done!

Cheers.
P.S.
I like the 300RUM, Nosler, NMI & Lapua Mag Improved over the PRC case.

I like are the key words, I like my 300WM a lot, its solid using 210 grain SMKHPBTs and just plain fun to shoot it was my first 1762yd gun out at Fouled Bore in OK.

This! I have 3 .300 WMs; 1 could accommodate nearly 3.7" COAL, and the other two around 3.5 - 3.6" COAL.
