Convince me…

Someone convince me to build a 300 RUM. Im also kinda thinking about a 300 RUM AI and even +P'ing it. Literally balls to the wall 30 cal. Im thinking i would prefer to run bullets between a 174 ELD-VT and a 230 A-Tip. Sierra bullets will be in the mix as well.

You dont need to provide me with your load if you dont want, but i would like to know some of your guy's build specs and what kind of velocities you are getting. Pictures are a bonus!

Unless you have the action you want to use already
I would get a 300 norma improved from alex wheeler, ryan pierce or dallas lane

Easy button is to buy 300 rum from dallas for sale in the classifeds

Lapua case will outrun a RUM if you're seeking maximum velocity

I would just go with a 30-378 Weatherby.

I'll provide a little extra info, i have a CA Traverse in 300 PRC that im wanting to do this with. So the easiest option would be a barrel swap. Also, with my Traverse, i believe i have a combo of not the best barrel and crap brass. I see many of other's achieveing much higher velocities using the same powder and bullets i usually use, hence the barrel swap option. Right now, i forget my charge, but im using H1000 with a 230 A-Tip and im only getting 2600 or 2680. I cant remember the exact, but i know im not getting 2700. Its to hot at 2700.

Keep in mind that a properly loaded RUM will be much longer than the CA mag box. There's no easy road there.

So maybe a 30 SM would be the better route to go? Or even just a better 300 PRC barrel?

Honestly I'd start over. You can't pick up a turd by the clean end.

You're not wrong, but new brass and a barrel would be a pretty nice polish job i would think!

I would go 30-33XC, it will trump all the others by a good margin.
The Rigby case is a marvel in what velocities it can reach with heavy bullets like the 245g Berger.
My own 300-416 Rigby Improved 9" twist gets above 3000fps with the 245g, above 3100fps with the 230g.

300NMI would be the next option in a 8" twist.

Cheers.

FWIW I have a 300 RUM in CA ELR. 220 Eldx mag length right at 3k fps with excellent accuracy. Only been able to shoot it to 900 yards but it hammers. Took 3 elk with it. 30 yards 100 yards and 550. Bullet did not hold together on close ones but all elk dropped where they were shot.

Switch powders
Try n570
And something in the 215 range

it's hard to push the prc's with the clicker issue

Why don't you think that you have a good barrel?
Speed isn't everything
I shot a mountain goat a couple weeks ago at 1060 yards with a 300 wsm @ 2775 fps with 200.20x bergers

Convince me…
