270wsm barnes 129lrx

Has anyone on here run this combo before and have any insight to share?

Rifle is a winchester m70 extreme weather 24"
Fed brass and fed 215s
Powder on hand is rl26, rl22, rl19, rl17, 2225, 2209, imr 4831 and superformance.

Target velocity around 3300fps

From online research superformance should see the velocity I want to achieve and is readily available unlike the rl26 and 17

The barnes are an expensive little pill so I'm hoping to get abit of inside knowledge before I start loading

Yes, and they are damned good. I really rate them.
I got that sort of velocity using R19.
The only reason I don't use them now is that I couldn't find any more of them so I switched to Hammers' which are doubly expensive.

Its good that they are available again.

Cheers tahr, ill add rl19 to the short list
