Smooth bore is how everyone gets such high accuracy anyways!

Re: worn out barrel
Just proves concentricity is a joke, and the pitch and yaw of the bullet means nothing when the bullet engages the lands. …LOL

Re: worn out barrel
Riflings are very over rated just as was already stated. This must be the new lightly rifled uber match barrel that is taking the accuracy world by storm.

Re: worn out barrel
All that friction from the rifling just slows the bullet down. Now that you got away from all those unnecessary lands and grooves. You can really develop a hot load...

Re: worn out barrel
Well if they start making 500 grain 22 cal VLDs you might be able to touch the lands. 6000 rnd 22-250 ai looks about like I would have thought

Re: worn out barrel
Out of curosity, what type of groups were you getting with the barrel in that condition ?

Re: worn out barrel
At what count did the the groups diminish? When do you think the riflings were shot out?

Re: worn out barrel
Thanks for the pics.
So you haven't been seating out to the lands for some time then?

Re: worn out barrel
Who was the manufacture of the barrel? It was asked but not answered, how many rounds did you put through the pipe?

Re: worn out barrel
Well, you'd be doing good to get 1500 rounds out of any barrel chambered in .22-250 IMP, let alone 6k.
That caliber, pushing the 90 grain berger, in a 1-7 twist, would be something I'd love to see.
Even just a plain ole' 22-250, and that combo would likely extend barrel life to something a little more reasonable.

Re: worn out barrel
the load i was useing when that barrel was in use was 50gr tipan hollow points with 40gr of ADIs AR2208 (1gr over there listed max) that where cronyd at abit over 4000 fps.
for some resion it will only get tight groups when going a about its max speed. i went to the 22-250AI over the 22-250 to stop the brass flowing as much, that worked nicely but the barrels paid the price its on its 4th one now.
