Thanks for the responses.34.0 gr of IMR4064 with the 53 gr V Max is quite impressive but 34.0 gr of Varget also works nearly as well with a 53 gr V Max bullet.The 53gr with 35 gr of 748 is as good as I've seen the 748 powder perform...Three great loads to see how the cold weather effects the pressures. Varget runs mild at 34.0 gr but shoots so well that I didn't work up beyond it.
