Re: .270 loads

Here are some 270 notes from my chrono at the range:

M70 270Win, 2x7 scope, 130 gr VLD 57.7 gr Re17 , 22" barrel, shooting off swivel bi-pod on the ground 8.75 pounds as tested with bi pod, scope, and sling
3129 fps, 3228 fps, 3228 fps

55 Re17 150VLD 3.385"
M70 22" barrel, 7X scope, 3023, 2996, 2969, 3003, 3009, 3003, 3009, 3037 fps

I would have bet that I could not do that, after all the deer I shot with that rifle with 130 gr Ballistic Tip 50 gr IMR4895 2875 fps.... out to 510 yards.

But the Re17 loads are no good. They had no pressure sign and the next primers were just as hard to insert, but Re17 changes so much with temperature, that I would have to reduce it way low [not knowing what temp I would be hunting at], and then it would still change trajectory with temperature.

So I would stick with the H4350.
The 270 even with wimpy loads is a real long range killer.

Wimpy is right when I read your guys' velocities. Not sure what's happening...maybe my chrono itself. But recently I've been seeing speeds about 50fps lower than the same recipes as before.

Note that this is a semi auto (BAR) so I think that limits the choice of powders vs. a bolt. (drive action reasonably etc.)

Anyway my 130gr TSX driven by 54.4gr H4350 is only going out at 2850 but shows promise in accuracy. That is only .6 gr under Barnes book max. I have flattened primers but case life is still good. But at that speed 500 yards is about the limit on deer (expansion vel of TSX & ft lbs). Strange that last year I chronod the same charge at 2900.

So my question is, what slower powder than H4350 would be good in a semi auto to boost the speed of a 130gr bullet? Or should I just move up in bullet wt if I want more punch at over 500 yards?

I have slower powders like IMR4831, some H1000, and some Rl25 but I in a RCBS or Hodgon manual that slow powders don' t do well in auto loaders.

(But wimpy or not, this load whacks deer and boar at a couple hundred yards.)
