7mm RM & 160gr BTHP

[stanway]

Any load suggestions for the 7mm Rem Mag and Sierra 160gr BTHP's?

I will be shooting it out of a Stevens 200 24" barrel and/or a Mossberg (Howa) 1500 24" barrel.

My powder choices are IMR4831, IMR4350, and IMR4064.

I have collected a bunch of data from manuals and Reloaders nest, but I was curious if someone has a good load they would like to share.

Thanks in advance.

James

My best results came from reloder 22 with 160 gr bullets. I haven't tried any of those powders, I would think IMR 4831 would be the best with the heavier bullets.

I havent tried the 160 sierra's but mine likes IMR 4831 with 160 Partitions.Good accuracy and low numbers in the standard deviation department.

I'd avoid anything faster burning than IMR 4831 or RL19 in a 7mm Mag w/ 160's.

For years I hunted with a 7mm Mag, loaded 160 gr. X's over 62.0 grs. IMR 4831.

If you're not opposed to trying a new powder, I'd be looking for some H4831sc, RL22, or H1000. All great 7mm fuel.

IMR-4064 From 43.2 grains to 53.7 grains
CCI-200 Primer

IMR-4350 From 50.1 grains to 61.1 grains
CCI-200 Primer

IMR-4831 From 51.7 grains to 63.0 grains
CCI-200 Primer

But I would use:
Retumbo From 65.0 grains to 71.3 grains
CCI-200 Primer

Hey James hows the baby. I use 160 partitions with H870, but did have a load that was fast and fairly accurate, 72.5gr H1000 it is a max!!! load in my rifle. Also 68gr.H4831 works very well and is a max!! load. Hope that helps. John.

Thanks John! Logan is doing great and growing like a weed.

Thanks to everyone for the suggestions. They will keep me busy for a while.
