Re: thought\'s on building a custom 300 rum barrel ?
[ QUOTE ]
I'm new to the big boy's. I just rebarreled a 204ruger with a 1.055 diameter 28" 1-11 twist,3groove and and cut my groups by 2/3 just in the break in.
So now I'm looking to rebarrel my savage 300 rum with a custom barrel and was wondering what changes to make as in twist-rate,number of grooves and in lenght to get the most out of it.I was thinking a 1.120 straight cylinder 1in11 twist 3 groove 32" with a JP Howitzer muzzle brake.It will be for paper punching and very little tripod hunting.bullet weight I'm was thinking 168gr up to 240gr just for B.C. still learning.So I'm looking to you fellows (experts to me) to guide me down this new path.If you will.Please.

Hi Timmy i would talk to Barney LAwton at lawtonbarrels.com and get a 30" 10 twist cut rifled 6 groove barrel off him. I would go with the largest barrel diameter you could fit onto the rifle i would look a 1.250" for 6" the taper it to 1" at 30" now i know you will say the barrel nut will not work have the barrel fitted without the barrel nut and have it trued aswell at the same time. The more area you can have around the chamber will help you with pressure and extraction on the upper level of loads.
Forget about the 168gr projectiles start at 210gr and go to 240gr. Barney has informed me that the 240gr Sierra Will stabalise out of his 10 twist barrels at around 2850+.
Get a thicker recoil lug fitted i think SSS makes them asd sels them. If you are looking for it mainly for target shooting talk to Joel Russo about his laminated stocks he has a direct copy of the A5 then a larger copy of it for the Chey-Tac action this is the one i would go with if i was you as it is a bit stronger. Then he has a F Class/Benchrest stock that is awsome if you are only going to be shooting it at targets and he has another new stock that is very good for target shooting and long range hunting.
I do have a question on what size the barrel threads are on your action if it is the early small thread action have the threads opened up inside the action to as large as safly possible if it could go to 1.062" the same as a remington it would be much better for accuracy and safety.
I hope this helped
I am in the process of building a rifle for a coustomer to shoot them at that velocity it is also to be a switch barrel rifle.
