I recently had forceman rebarrel my old 'Jeep Gun' in a Blackfeather stock with one of Jon Wolfes mod/std wt 22" 5r/20 barrels and am now trying to get it to shoot...
I installed last Sunday Midways 99 dollar unitized gas assembly and it did seem to help some along with relieving the handguard some. Have been using hornady 168gr hpbt's @ 2.81 coal.

Any thoughts guys? What works for you?

Trying to get a good deer/jeep play gun here that is as accurate as can be.

What I shot today with her:

Seems like what you're doing is working!

 

[Grizzman]

I'm not able to measure your groups on my screen.....what are your results?

What are your expectations? "As accurate as can be" isn't specific enough.

You have done well again Jeff. Good shooting. Way better than most could do with a bolt rifle, but then you have been working at it.

Have you tried adjusting the height of the op-rod guide block and running tests with it in different positions? Also check for light between the heel of the receiver and the chassis. If the heel is free-floating, it needs to be bedded. If it's touching, you should be good.

I also found that with lighter barrels, I need to shoot 10 rounds to warm up the barrel. After 10 rounds, let the barrel sit for about 2 to 5 minutes, then shoot one round every 60 to 90 seconds.

If the barrel cools down too much, you need to start all over again.

Tony.

Thanks Tony, I will check the heel again in very good light; I gave the op-rod guide screw 'up' two flats early on and it did seem to group better

 

[Ted Brown]

Practice!

 

[Johnb2488]

run those with varget at 43.3 grains seated at 2.760. Thank me later

 

[86cookiemonster]

that looks pretty darn good. I know bolt guns that would be envious of groups that type of shooting.

 

[SteedGun]

How many rounds down that new barrel?

 

[SteedGun]

On a new gun especially a 30 cal I will use some of these. I bought one kit and will use like 3-5 bullets on a new rifle during barrel break in.

You might want to experiment a bit with OAL or even try a bit of neck sizing.

Brother JEFF JP_N_JJ: What is the barrel twist?

Jarhead

 

[JEFFJP_N_JJ]

Steedgun I have maybe approaching 150rds I'd guess and thing it is breaking in.

Jarhead! It is one of Jon Wolfe's mod/std weight 5r/20's. 22" 1/11 nitrited. Am really liking it so far and need to start finding a loading it likes.

OK. Just my opinion. I don't sweat accuracy until I have at least 300 rounds through a barrel. Like I mentioned above I will use a few lapping bullets if I think it needs more help cleaning out burrs, etc. Also, with my M21 I found that loads that are about 3/4ths of full power group the best for me so if you are not needing to reach out too far maybe try some different loads.

 

[JEFFJP_N_JJ]

Ok guy's here is what I got out of her today...

Thanks Tony! I think slowing down my shooting did help with this light weight barrel

 

[86cookiemonster]

That is some good shooting.

 

[anthonypd]

That’ll work! Good shooting
