| I like Reloader-22 and IMR 4831 for the light ones(145-154). H870 or H570 for the 175 grainers.

| I have my best luck with H4831 and 4831sc with the 140's. My 7 mag won't shoot any bullets heavier than that worth a darn.

| IMR 7828 and V-V N160. Both powders put my 7m/m mag (26"bbl) over 3050FPS with 160 grain bullets.
I also load Sierra's 160 grain HPBT interchangeably with the partition, and both shoot to the same point of impact with N-160. I really like that powder. |

| I am using Ramshot Magnum with good results. It is both easy metering and temp insensitive. |

| I have been using IMR4831 with Nosler 150 gr bullets, the NBT will group 1/2" @100 and Partition 3/4-1" at 100. In this particular rifle I have found closer to max seems to provide the most consistant accuracy for a 3 - 5 shot grouping (1 - 2 gr below posted max in Nosler 4th).
I just got some RL22 and loaded it behind 140gr Barnes TSX, it averaged under 1" with 1 grain off published max (69gr). However I experienced a sticky bolt, yet no signs of excessive pressure shown. Does anybody find RL22 fincky in high heat (it was over 80 the entire time I was shooting last evening)? I also found stick with my 67 gr tsx load and even a few factory loaded NBT's, so not sure if my throat is just tight or what. Never had this type of trouble in the past then again I also never have shot when so warm....ah isn't it fun!
Best of luck |

| My best 140-grain load uses H4831, and for 175-grainers I prefer IMR 7828...

| I've had excellent results with H1000, and like the fact that it's a Hodgdon Extreme powder and can be relied to be temperature insensitive. Very consistent behind Hornady 162 A-maxs and 154 SSTs.
