Hart HV .308 barrel, 1-9" - what to do with it??

Hello everybody, I've been lurking here for awhile and want to say thank you for all the great information provided by the members of this forum. And, I hope I can benefit from your expertise with a question.

I have a HV taper barrel in .308 with a 1-9" twist that will finish at 26". The good thing is I got it for a steal from a friend, but my dilemma is I don't know what to do with it. Is the twist too fast for a 308Win? Is there any cartridge that would be a good match with this length barrel, twist and caliber? I would like to build a gun for 3-600 yard shots for upstate PA dear and the occasional unlucky ground hog.

Thanks in advance for your recomendations. I want to start this as a winter project and need some help getting off square one.

Regards,
Joe

WOW....

Your looking at the ability to stabilize the 240 gr SMK's..

you need to build ya a 30-378, 300 Ultra, 300 Tommy or somthing of the likes..

Most .308 Win. only need a 11 twist at the most....

Considering the ranges you have in mind and the barrel length, I would build a 300WinMag, or possibly a 300WSM.

I would have to agree with MontanaMarine. The 300 win mag or something like that.
Crow Mag

As mentioned before, the 1/9 will stablize the heavy .30 cal. bullets. You really only have to determine how fast you want to drive them, the rest will fall into place.

Re: Hart HV .308 barrel, 1-9" - what to do with it??

Thanks for all the input. If I'd look at a 300WSM, what type of performance could I expect from the heavy bullets? I'm starting to formulate the conclusion that with this barrel length (26"), and if I want to play with the heavy bullets, I may do best by sticking with 300 Win Mag?? I admit I'm bitten by the bug to drive the bullet as fast as possible, but I suspect that with any of the "big" cases (300RUM, 30-378, etc...), the increase in velocity per increase in case capcity over the 300WinMag starts to drop dramatically??

Joe, I think you've nailed it. Putting over 100gr of powder through a 26" pipe will gain probably 100-150 fps over a 300WinMag. At the cost of more powder, more blast, more recoil, and less barrel life.

Only you can decide what will make you happy though.
