Hi-Power Jack Posted May 5, 2017 Share Posted May 5, 2017 Guess it depends on the barrel and the ammo used, but how long does a 3-gun .223 keep its accuracy? Thought I saw something on this few years ago - compared different barrels and different types ammo (steel cased, etc). Link to comment Share on other sites More sharing options...
TonytheTiger Posted May 5, 2017 Share Posted May 5, 2017 Good question. I hope I don't have an answer for at least a couple more seasons. Link to comment Share on other sites More sharing options...

TonytheTiger Posted May 5, 2017 Share Posted May 5, 2017 I've been running a Stretch16 barrel for just over a season now, it's only got about 5k on it so far. 95% of the ammo through it are my light blasting loads. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted May 5, 2017 Share Posted May 5, 2017 I would keep a spare barrel on hand, because you know the one on the rifle will go to hell just before an important match. Link to comment Share on other sites More sharing options...
DocMedic Posted May 9, 2017 Share Posted May 9, 2017 (edited) I put 13k in my JP 18inch light weight before replacing it (Bought it back in 2011). It would group solid under MOA when cold but as it got hot it would open up to about 2-3MOA and shift a little. I'm keeping it for my Bay run local matches.

Kirkwoodious Posted May 10, 2017 Share Posted May 10, 2017 I'm 5k into my stretch 16 and still hitting targets at 600 and grouping under 1 inch on 6x mag with no problem. Link to comment Share on other sites More sharing options...

They were dumping ammo as fast as they could. Not really a valid test on the way anyone actually shoots, even 3-gunners who are probably harder on barrels than anyone except guys at machine gun shoots turning money into noise. What would be really interesting is that same test done with a realistic firing schedule. Typical of 3-gun matches, say, 20-50 rounds down range in 10-60 seconds, then allowed to cool fully before doing it all over again. It proved that bi-metal jackets are harder on barrels, but how much of that was the excessive amount of heat that was generated. Link to comment Share on other sites More sharing options...
MotorMouth Posted June 16, 2017 Share Posted June 16, 2017 I can't remember the brand, but I had some off-brand pencil barrel that was shot out in a few hundred rounds. The current pencil barrel is from Adams and it's been awesome. I think it has 4000 rounds on it and it's still just as tight as it was before.
