RE: browning a-bolt owners, step in plz

I think my Tikka has the same issue. First 2 shots are usually 1/4" followed by #3 opening it up to 1.5". I'm still testing this but if this is the case I'll just have to wait longer for the 3rd shot to have nice groups.

My Abolt I used to have would never shoot better than 2" at 100 yards. Good enough for hunting i guess but I wasn't happy with it. I glass-bedded the action, reloaded for it, and even sent it back to Browning. They returned it with a 50 yd target with 3 holes 1" apart, saying that was within factory specs. Probably good enough for most people but not for me. I sold it and bought my Tikka and have loved that rifle so much more I never even think about my Browning except at times like this.

The a-bolt that I have done a good bit of shooting with is a 270wsm and I have never had this kind of problem. Sounds like a pretty crappy answer you got from Browning.

f I fire 8 rounds one after the other at 100yards I get the following:

If you keep overheating a lighter weight barrel by regularly firing 8 rounds one after the other,you will greatly increase the rate of throat erosion and the accuracy will get worse permanently.

Any of the a-bolt rifles I've ever seen (as well as bout ALL factory rifles) are good for bout 2-3 shots before the barrel starts walking. This is natural occurence with factory sporter weight barrels. I recently posted about cyrogenically stress relievimg barrel and had people that had NEVER had it done tp verbally attack it and cruify me! As to 3 vs 5 shot groups,my acid test is 5 one shot groups-shoot a round,wait hours or days between shots at same target. THAT will give you HONEST cold barrel accuracy. I have most of the barrels I use cyro'd And it eliminates ALL barrel walk and usually a tad better on accuracy. Another thing I do is handlap ALL my barrels regardless-DO NOT firelap-I've seen barrels ruint because of firelapping. I do these these proven accuracy enhancing methods regardless of manufacturer/model/contour.
By the way-a-bolt is my favorite action to build rifles on but VERY HARD to find 1 cheap enough.

Dad gone, stalking, you and i are on the exact same page these days besides the carbon arrow debate:D. I ruined a good barrle with firelapping.

Also, I paid extra to have a krieger barrel cyrogenically treated another few cycles. It actually had great cold bore performance. But I think I went way too small in barrel diameter, so it still went all over the place after 4 shots. But it was a hunting rifle.

You cryo'd barrels AFTER they were drilled?? I thought that the stress relieving would be done before drilling. Guess I need to read up on that a little more.

To be honest, not sure if it was before or after. I just bought a barrel from krieger, and they give you an option for more cycles to be treated.

RE: browning a-bolt owners, step in plz

Bigcountry-I consider that an honored compliment:D. Some of the top barrel makers relieve stress between every step AND after all machining that would induce stress. Just about any machining steps cause stress such as drilling,any type rifling other than cut,and even turning down blank will create stress. Cyro works so well because it's done after all these steps are done.I too have heard of barrels becoming more accurate but the main reason I have it done to almost all barrels on rifles I build is it usually stops barrel "walking,and the throats last longer. I built a ruger #1 in .416 rigby necked down to 7mm,got 2 barrels 30" long 1 was cyrod and other wasn't,and conducted testing on accuracy life,velocity loss,etc and the cyrod barrel throat lasted almost twice as long.
