Found a new load for my 7 Mag I think today. 67 gr of RE 25 pushing a 168 VLD at 2915 avg. I know its not the velocity everyone else gets out of theirs but I can't ignore a group like this. Has anyone had any problems with RE 25 and temp swings at all? Weather was nice here this weekend, hopefully everyone got out and did some shooting.
RL25 is a little temp sensitive. If you use Win Mag primers it does take some of the cold weather blues out of the swing. Norma MRP-2 is a less temp swing powder that has the same or at least a very similar burn rate. If you can find some you might give it a try. Great shooting!
I might have to give that load a try. I'm having great luck with H1000, but it's always nice to have more rabbits in the hat for later.
I keep hearing that about H-1000 but my rifle seems to absolutely hate that powder, same bullet seatings and many different loads with it and it just wouldn't produce. This rifle likes a lot of bullet jump too which I am not used to. So far Retumbo and RE 25 have been the clear favorites so far.
I'm having trouble getting a load that will shoot with 168 vlds. I started with 69.5gr of h1000 and all i have adjusted is seating depth. I started touching the lands then backed out .010 then out to .040 then out to .080 then .120 best groups were at .01 and .04 off i shot six-shot groups and none were under "1. I have retumbo, h4831, imr 4831 and re 17-25 any suggestions where to turn next? should I stick with the best group's seating depth and load an assortment of powders to see which powder groups best?
p.s. Im shooting a brand new custom shilen 28" #6 1-8 twist barreled Savage off sand bags with a sightron siii 6-24. I broke in the barrel (per shilen instructions) with low velocity (minimun powder charge) 150gr cheap bullets before i started trying to work up this load.
best group so far has been with 120gr hp varmint bullets i shot as foulers :(
