Impact shifts post cleaning?

[TradLife406]

I cleaned the carbon out of my 22 elkmoor barrel after the last range session. She was a dirty girl.

Ran out to shoot after work and was hitting a foot left.

To be ffffffaaaaaiiiiirrrrr my scope is an Arken so it probably lost zero. But I haven't had an issue with it or the other one yet.

Anyone noticed a huge jump before and after cleaning?

I used to see a small jump then started using lock-ese as a final step, fixed it for me.

 

[BLJ]

Had the accuracy gotten worse prior to the cleaning

A huge jump? No.

I’d suspect something else is at play.

A foot left is a seriously damaged crown or wildly shifted scope.

Not only have I never had an Arken scope shift zero while cleaning a rilfe, I've never had any scope do that, ever. I've also had my Arken's in gun boots and such over hundreds of miles on my UTV/ATV and never had one lose zero that way either.

When I USED to clean my barrels I'd always see a shift and a widened spread. We're talking maybe 1-2 mils off and say 1inch group turned to 1.5


But a foot?! Naw somethings wrong here.

Did you take the action out of the stock and not get it settled in properly after?

 

[IAm_Not_Lost]

No cleaning will cause a foot shift at any typical zero distance (say…out to 200 yards).

I also doubt your scope just randomly lost zero without there being any drop or other damage to it.

I feel there is something else at play, or you need to re-evaluate.

I ran a brush through my barrel a few times before my last zero check. I had also hit it with the screw on swab, but no patches.

I figured there was probably some residual lube from the swab. So I shot three foulers before my regular ammo.

Shooting at a 4" target, my first shot missed the paper entirely and the next two were close enough. The following three with my regular ammo were right on.

Same. Stopped cleaning barrels, stopped having this issue.

Agree, though, a foot is a much bigger problem.

 

[5MilesBack]

I only clean my barrels when I see a significant dropoff in accuracy. Then after I thoroughly clean them, the groups open up until well-fouled again. But I'm not sure I've ever had a zero change from cleaning.

As others mentioned it might take 6 or more rounds to “foul “ barrel again. I wouldn’t go chasing shots with adjustments till after that

I'd be getting another rifle.

I'd be getting another rifle.

That's always the correct answer

 

[JGRaider]

Can't have too many......

 

[TradLife406]

Yeah not sure what happened. I'm guessing it was shooter caused.
I cranked it to the right and then actually ended up having to go back left. Maybe my alignment was off.

Excited about the S2H school next year. Hoping some FORMal instruction can help me out.

I did notice I was fighting the gun too much. Had to lower the bipod legs. Need to work on not compromising my position. Slow down.

Cleaned a barrel the other day and had a 100 yard 6 inch group afterwards. I haven't had to adjust the scope in a decade on this rifle so I was panicked. Took 12 shots and started punching holes again. I usually blow a couple shots out but never has taken 12 before.
