IMR 4064 in 7mm rem mag ????

[chad44]

I just bought a 7mm rem mag with a 9.5 twist. I have been trying to figure out what powder to buy and it seems most use H1000 or retumbo. I was looking thru a reloading book and noticed that IMR 4064 comes up in quite a few columns/bullet weights. I was excited to see this because I have six lbs for my .243. Has anyone used this in a 7mm or is there a reason I shouldn't? Thanks. Also will Berger 168 gr be ok with that twist?

I've used just about every powder in the 7rm over the last 30+ years. RL22 behind a 160gr Accubond has worked VERY well in the last 3 rifles I've worked up loads for. Load it to around 3000fps or a touch more, if it won't shoot, something else is wrong.

4064 is too fast.......much better choices.....

Think slow & fill up the case.......

H4831....RE22....VV160...RE19....H4350

to name a few......

H4831 for the 7. varget or I4064 for the .243

I am also a fan of the H4831 in the 7mm Rem Mag. The powder seems to be ideal for the 168s
in the 7 RM. Also the 4831 SC should work well.

Any of the new powders that have close to the same burn rate should work.

4064 Is a great powder for the 120s and 140 gr bullets but is a little fast for the bigger bullets.

4064 is too fast, even with light bullets. Since you are going to have to buy some powder, buy H1000. According to Berger, a 9.5 should be good. They say that bullet needs a 10 or faster twist.

If you want to use an IMR powder, try 7828 or 7828ssc. I've used this behind a 150 NBT and a 160 Accubond with sub MOA results in both

H-4350, IMR 4831 or RL-19. Stay away from 64 and others similar.

I like IMR 4064 in my .3006 and my .308, it seems to be the best powder for my rifles.
I have tried a few in my 7MAG with IMR 4064, but for my MAG realy likes IMR 4831.
