Got the new X-Caliber 224 3 groove 1-8"t barrel in a few days ago and this weekend decided to spin it on and give it a go. Think this was the fast fastest load development I've ever had, that group was 35rds in. Ran the bullet .010" into the lands ran up pressure and backed off until it tightened up. That barrel was one of the easiest I've dealt with.

All smith work was done by me. The action is an old 40x that had lot of extra holes that got welded and refinished. The stock is a $35 Numrich special with pillars and Devcon 10110. The bolt has a savage head with modified firing pin, timing has be modified, 30lb spring, weaver 20moa base with Burris insert rings with 10moa inserts, jewel trigger @ 8oz.

Adam,

Can we see a pic of the bolt with the Savage head? Did you do this mod or?

Thanks, Paul

Paul, this is the short version but, I used a long action bolt and chopped the head off. From there I timed the cross pin and ground the firing pin. I didn't use a crush washer or baffles, I made it just like Shilen did. The primary extraction has less than .005" slop and it's amazing what a difference it makes. The cocking piece and upper lever on the trigger were re-ground to .0000" cock on close which decreased firing pin time but that's a whole other ball of wax.

Adam,

That is very interesting and quite ingenious. Always cool to see something off the beaten path. Thanks for taking the time to post.I would imagine you have great primary extraction. Very cool mod.

Regards, Paul
