Re: Building up on my Weatherby action????
If you get your calipers out and measure the mag box, you'll see it's about 3.5" long. The 300 RUM case spec is 2.845 and the 300 WM is 2.620. If you do the math, you have .655 left in the RUM and .88" left in the WM for bullet nose. That doesn't cut it for my .308 bullets. You could use a 180 E-Tip or AB in the WM but you would be seating them deep.
I like the Howa/Vanguard actions but I use them for shorter cartridges. I'm having a 300 RUM built now on a 700 action with an extended box and the regular box is a little longer than the Howa box.
I wont be using any more 700 actions for any more builds. They need a lot of spendy mods if you're going to do it right. So if I do any more longer cartridge builds I'll be using a custom action from the git go.
A 300 Dakota has a case length of 2.55 which is a little better but still would br to cramped for a lot of bullets.
