Problems with new gun

[bigngreen]

Barrel has been nitrided from what I've been told nothing penetrates that I pretty naive on nitriding. Had another 20 moa rail on before was fine maybe this one is a 30 moa have to check that out

I used to nitride a few barrels at a time and you have to spend some serious time cleaning, like clean it like you hate it!! I have pretty decent stuff for cleaning barrels and even using KG bore polish and evey manner of stuff I put a good two hours of serious work with the barrel in a barrel vice till I'm happy.

Bullet 140 eldm powder vitahouri n165 55 grains cci 250 mag primers.

It's a scope issue, most likely…
I don't think it's barrel related..

Scope issues done make bullets hit paper sideways!!

I'd bet something happened when it was nitrited.

GregH118,

What is your load for your 6.5 max

All of my load Data is posted on this Forum under Hammer Hunter load data or Absolute Hammer load data. I shoot both.

I'm thinking nitriding also just have to get anorescope and see if we can see anything

 

[GregH118]

Thanks everyone for your help I'll post after we look at it with borescope

Carful with that bore scope and your other rifles. They tend to make folks think they need new barrels. I wouldn't be surprised if they start coming with coupon for new blanks lol

I would check the twist , if it's a 1-7.5 or faster you may be spinning the jackets off of those 147 gr eldm bullets , it sounds like a over stabilizing of the bullet , or something going on with the nitriding . Post # 37 from Idaho Lefty is on the right track . If I were a betting man I bet that barrel is a 1-7.5 or faster , too fast for 147 eldm s that can be a good thing in the long run , keep us posted.

We are going to try Berger 156 next. Stock and barrel have been check

I have same gun but bartlein barrel

"If" your rifle is all set up and your barrel has the same twist rate as your barrel, you might consider shooting his ammo/load off yours as part of your troubleshooting. Or your ammo/load to his rifle—just a thought for your consideration. Good luck!
