6.5x47 lapua barrel life?

[diderr]

what is the expected accurate barrel life w/ a 6.5x47 lapua w/ zero hot loads? better or worse than a 260?
thanks,

I have heard a couple of arguments regarding this, but do not know the answer. But I do know that performance usually comes with a price. Both have relatively long necks but the .260 has a tad more performance so I would say the 6.5x47 has a slight longevity advantage. I would guess that the 6.5x47 lapua will go a miminmum of 3k rounds the way I load it. I would bet that most will get more than I will get. 123s at velocities too fast to post lest the pressure police come in the dead of the night have a way of eroding a barrel

I think when you figure in time prepping .260 brass that the 6.5x47 looks even better. I have 12 loadings on my 6.5x47 brass and it still feels new when I seat the primers and bullets. For some reason the necks stay more consistant with the 6.5 version of the lapua case. In the 6mm version neck tension starts going downhill around 8 loadings and I do not anneal.

thanks, that explains it well. I'm going to buy a SA remmy 700 action w/ my stimulus check to begin the project lol.

Haven't been able to compair heads up the 6.5x47 Lapua to the 260 , I have a couiple 260's and use 308 Lapua brass to make my cases ,if you wanting to shoot the 140 class bullets real fast out of a short action then I'd suggest the 260 or the 260 Ackley as the added capacity with a 28+" barrel will do that but if your not worried about an extra 100-150fps then the 6.5x47 Lapua would be my choice.
1) its a good big shorter and that will allow you to feed from a mag much easier without alot of trouble and the need for an extended mag box
2) Less powder will not wear the bore as fast so it should get a decient amount longer barrel life
3) Lapua brass ready to shoot right out of the box

BUT

the Lapua brass for the 6.5x47Lapua is almost twice the cost of 308 Lapua for the 260 and if you even "need" that extra FPS the 260 will be more likely to give it to you

But with the new Berger 130gr bullets I'd certainly build a 6.5x47 Lapua without hesitation

with a 30" barrel can one expect 2850ft/s with the 139grain scenar out of the 6.5x47lapua or would that be running it hot? what about the 130grain, how fast can it be driven from a 30" barrel?
