300 RUM twist

What barrel twist do I need in a 300 RUM for 200 gr bullets? Looking at a 25 inch barrel. Also is there any factory ammo with 200 gr bullets?

Cant tell you about barrel twist but federal makes some hot loads with a 200gr partition that fly really well out of my 300rum I bought them because it was the only way I could find nickle brass.

Most likely 1:10... I think.

1:10 works fine for up to and including 240SMK's at 300 RUM velocities.

Guys, I don't know too much about the 300 RUM, but is that a long enough barrel? The shortest I've seen is 26", but many that were even longer.

1:10" should be fine for all bullet weights up to 250grs.That's standard on most .30 cal rifles,I think your barrel length is a little short for that cartridge;28" would be better.
I can't think of any factory loads that have 200 gr bullets,there isn't that many in any weight as yet,we'll have to see if Remington are going to offer more bullet weights in the near future,it depends on how many they sell.
