Rifle almost finished

[WisconSniper]

Im nearly finished with the 6mm-284 prairie dog rifle i started early this spring. Because of the lack of funds, (gunsmithing student and what-not), I am using a Savage M12 action that I've blueprinted the ever living daylights out of in my feeble attempt to make it run in the dust of the Surgeon and Kelbly actions. I faced the reciever, reamed the raceway out, chased and oversized the action threads .010", and got a Pacific tool and gauge CNC'd bolt head.

I installed a Sharp Shooter Supply competition trigger, and a bolt handle from ebay cause i liked how it looked. The SSS trigger is phenomenal and is definitely the best trigger I've ever used on a Savage.

To ease the working of the action, i made a bolt lift kit out of a rifle case head and a ball bearing as well as clipping 2 coils off of the firing pin spring. I also polished the cocking cam, cocking pin, and back of the bolt where the baffle assembly in front of the bolt handle rides, and the small cam between the bolt handle and baffle collar. The raceway and locking lugs where also lapped so smooth cycling.

The barrel is a special order Shilen select match stainless steel barrel measuring 1.35" at the breach, 9" of straight shank, then tapering to 1.125" at the muzzle and 34" long. I had an adjustable pilot reamer made by PTG along with matching gauges. Thrown in the mix is an aftermarket recoil lug from SSS that i surface ground to ensure squareness (i found low spots on mine.) To support this heavy barrel i machine a 2 piece barrel block out of aluminum, bored within +/- .0005 of barrel diameter.

All this is topped with a Trijicon Accupoint 5-20x50mm scope with an amber mildot. I have yet to get a stock (college money problems) but plan on shopping around for one in the next few months.

The 6-284 is a great cartridge, I cannot forsee a time when I do not have one in my stable. Are you going to run light bullets at hyper velocity or heavies at high velocity? That barrel block looks sweet, well done. Are you going to float the action?

I haven't decided if I'm gonna float the action or bed the block and action together. I plan on shooting 107gr bullets around 3500-3700fps.

Not being a 'smith in any way shape or form. I would see a potential for binding if not done correctly. Is there any relevance to that?

I'm launching 107's @ close to 3500 from a 28" tube, you should have no trouble beating that. Run Lapua brass & i'd recommend giving Ramshot Magnum a try. RL-33 might be a great choice as well.

What I would probably do is inlet the barreled action in then inlet the block and leave a little extra underneath. The fill the void with glass bed or steel bed and support the barrel to keep everything inline. I'll cross that bridge when I get there.

Very interesting, I hope you can continue to update this thread as your build progresses.


BTW- That "Got Barrett?" sticker is awesome.

Thanks, ill be sure to keep you guys up to date. This is going to be one of the better builds i finish. I'm anxious to see how she groups.

Don't you think that is a little to much barrel for the 6mm-284? I feel like 28" should be about your maximum length until you go over the other end and start losing velocity instead of gaining it.

I wouldn't think so. It's a pretty substantially overbore caliber as it is. This will also give you the ability to heavy doses of slower powder than normal. Plus, as a high volume PD shooter, the OP will have to set it back at least once per season.

Very cool. Can't wait to see the finished product!

I'm figuring on a barrel life of about 900 rounds before accuracy dismisses so, you are correct sir!

You might want to try the 105 Berger hybrids too. They have a higher BC of .547 vs Sierra's .505 I shoot them in my 6mm-284 with RL-33. Getting 3535 fps with 28" barrel with excellent accuracy.

I agree with Outlaw6.0 keep us updated.
