RPR .308 accuracy issues RESOLVED

[v0lcom13sn0w]

I have had that happen once as well, but my glass is in a Burris PEPR one piece and all is torqued and tight.

the mount isnt "bridging the gap" between the receiver and handguard is it?

 

[Kruel J]

Got the mount as well. Your good to go.

Dude.....wow. This is why I devote so much time to NWFA. Best. Members. Ever.

Nope, nothing touching at all. Maybe even a little tall.

One of the Issues I heard about with the Rugers had been in the Barrel Bedding. I think you should give it a bit of polishing, check the bedding and STAY with the same ammo. Using "whatever" Ammunition during break-in is one thing but if you are checking for Accuracy then I don't think swapping out from one Group to the next is going to work.

Makes total sense. But 4 MOA? I would expect that with even bulk garbage I could do better than that.

ahhhh i see the problem.... you need a suppressor

Yes, I do. And if I can get the darn thing to tighten up I'd be more than happy to have it host one. But right now I want to throw it out a window!

if we ever meet up to shoot youre more than welcome to thread my can on there and try it out (if the brake comes off easy)


so youre saying the bolt gets harder to open and close the more you shoot it?

Yeah, harder to close. In fact, I even had it jam once trying to seat a round. Full mag, empty chamber and the round wouldn't go into battery. I had to drop the mag and start over. WTF?

 

[v0lcom13sn0w]

OHHHH have you looked at your brake to make sure theres no strikes on it??

shoot it w/o the brake?

Can't blame you. You got out shot by a sub par shooter with a much better rifle!

ya. WTF? wondering if theres some debris in there.

as a handloader the only time ive had a bolt be hard to close is when i failed to resize my brass properly.

ive had bolt be hard to open from over pressure before too.

FU!

 

[Kruel J]

These are the best I can do with my phone. The bore is clean and the rifling looks even. At least to me. How can some brass shavings affect it that much?

 

[11Charlie]

Throws the round off trajectory?

Just a guess

 

[v0lcom13sn0w]

everything look straight? barrel is going straight thru the handguard and not more toward one side? is it possible the barrel nut might not be tight?

 

[Kruel J]

OK, but how? The projectile travels down 20" of rifled barrel....so if the bolt face and feed ramps are crudded up with brass shavings how could that affect the trajectory? And no, no strikes on the break @v0lcom13sn0w. But great question and made me look!

 

[Kruel J]

To my untrained eye, everything looks true and is tight.

 

[v0lcom13sn0w]

To my untrained eye, everything looks true and is tight.

not sure this would affect anything since a scope is zeroed to the barrel bore but assuming something is coming in contact with the handguard (bipod, shooting bag, lead sled) could the handguard be flexing or vibrating throwing it off somehow?

without going too far down a rabbit hole im still thinking keep shooting it and take a different scope with you to the range.

every rifle ive bought has been good to go out of the box or right off the bench after ive built it. i really really hope you get this worked out... the nice thing is @SKrueger is such a good guy it aint even gonna cost you(minus gas and ammo....but u get to go shooting) to try a different scope.


we all should go shoot together someday.

wont have much freedom in a few weeks for a while though. gotta take care of baby.

brother, i have tons of brass shavings/unburnt powder amongst other crud in my guns from shooting suppressed and accuracy still holds true. i dont think a few brass shavings are an issue
