7383 & temperature

[singleshotbuff]

Gentlemen,

I have some 7.5X55mm loads using IMR-7383 and 150gr Jword bullets, that I have worked up in 20-30 degree temps. I'm getting about 2650 f.p.s., with no pressure signs. I'm thinking of increasing the charge to get to 2700 f.p.s.

I am a bit concerned about the pressures when I shoot these loads in warmer weather.

Does any one have any idea how temerature sensitive IMR-7383 is?

Thanks for any input.
