300 RUM questions?
Anyone have any experience or opinion on the 300 Rem Ultra Mag? I’ve owned 3 different 300 WinMag rifles and they just were not what I wanted, so I’m wanting to build a custom and chamber it for 300 RUM. The ballistics of the RUM seem to be right where I want them compared to the WinMag, but I haven’t heard much about what shooters think of it. I want more than the WinMag, but not as much as a 338 WinMag or Lapua. Also, what about brass? Does any company besides Remington make brass for the 300 RUM, like Lapua or any other higher grade? Here’s my blueprint for my next rifle, so feel free to give any thoughts on it. Nesika Bay receiver, Lilja barrel, Nightforce NXS scope, Jewel trigger, McMillan A5 stock, and some kind of muzzle brake.
I have a Remington 300 rum Stainless Fluted Sendaro barrell with a muzzel break, a 6.5-20×50 Leupold VXIII, Harris long bipods.and love it . I use all remington brass and cant tell u how much i have reloaded it. No stretching or crack on them only a few have cracked and i pitched them.
Check with Midway USA or Cabelas for brass. I use IMR 7218 Powder 89.4(of course start lower and work up) grains and Combined Technology 180 Grain Ballistic Tip Boat Tail coated bullets(ballistic coefficient is about .50), Federal Magnum primers. Not sure of the FPS, no Chrony. I have the shot down cold. I shot a buzzard this deer season @ 493 yards. Pretty much exploded him and I got some great pictures. Your talking about spending some big money on the rig your wanting to build. Are you going to do competition shoots? Of course my gun right now is worth if purchased new $2,000. Good luck
