300 RUM rebarrel

In the thinking stage of a 300 RUM rebarrel project.

I have a Savage 111 in 300 RUM, w/26" sporter barrel 1:10 twist, that I'm thinking about upgrading to a custom barrel. It shoots about 1 moa with 200 SMK handloads, but heats up extremely fast.

I'm hoping a bull barrel will do 3 things - allow me to fire more shots before getting the barrel to cooking temperature, be a little more resistant to vibration, and add a little weight to reduce felt recoil.

I like the 200 gr SMK's, and would like a twist to work with these bullets.

Looking for opimions on twist rate, # of grooves & lands, and barrel length, and barrel contour. My intended use is an "over the top" varmint rifle (I want to kill groundhogs deader than my 22-250 does [img]images/icons/wink.gif[/img] ), and long range paper

My 30" PacNor 1:10 with a 5 groove bore makes the SMK's sizzle with H1000, RL25, and retumbo. It does however like the 216gr clinch river better.
You try to get closer to the target,..and I keep trying to get further away.

Re: 300 RUM rebarrel

Seems like I'm wanting to go the opposite direction as this forum. I want to rebarrel my 300 RUM with a 1:14 twist so I can get good groups with 125gr Ballistic tips.

The way I look at it, if I want to fire a 200gr bullet I'll move up to my .338 RUM. What am I missing (besides the target in windy conditions [img]images/icons/smile.gif[/img]?

I usually don't have time to use a rangefinder so I need to get off a quick shot at 300-400 yds, therefore I want the flattest shooter I can get (and least kick).

Re: 300 RUM rebarrel

If it were me I'd call Pac-Nor and have one of their barrel made up for me , I'd opt for a 28"+ with a 3 groove 1-10 or a 1-11 in 5 groove.
Their is also a fella here that will prefit a Rock Creek barrel for your Savage , I believe his handle here is "Carbon-man" , I could be wrong but its close to that

Re: 300 RUM rebarrel

b1g_bOre, at short range 300yds and in, terminal performance. Medium range, 300-600yds, terminal performance, and wind drift, long range, past 600yds, terminal performance, wind drift, and drop. Using your example at 400yds, with a 300 yard zero, MV of 4000fps for the 125gr, and 3000fps for a 220gr MK, there is a difference of 2.8in, favoring the 125gr. Its up to you if that 2.8in of drop is worth what your losing, in regards to performance. [img]images/icons/wink.gif[/img] YMMV.
