Ive only loaded for a few different calibers so I havent tried many different powders but it looks like IMR4064 is among the bulkiest judging by dipper size. vs grains.

For my 7 RM I would like to use as light a charge, while filling up the case as much as possible. Im guessing this may cut down recoil while getting as more shots per lbs? Is this correct? Do you have a better powder suggestion?

I have a bunch of speer HC 160s leftover and would like to use those but I dont see a load for it w/ 4064 in my book. anyone have a load?

My Nosler #4 manual lists 4064 for the 160 partition...

Minimum charge is 49.0 and max is 53.0.. However, 4064 is the fastest powder listed and the load density is the lowest ( 61 to 66 %)..

4064 is a pretty fast burner to be using in a big belted case...Putting too much of it in there is a good way to set up a bolt, or worse...I've seen it happen ..

I really think you'd be better served to stick to slower burners for heavier bullets in the 7mm RM, like RL-22, RL 25, 4831 or 7828, and save the 4064 for medium capacity , non-overbore cases like the .308...

Good luck....

Yeah, I think your right. Ill try the reloder 22 , the staring load is about the same velocity the 4064 max load w/ only about 6 more grains of powder, and probably better accuracy.

Thanks

Let us know how you make out...

BTW.. Where abouts are you in NY...??.. I'm in Steuben County...

I'm down here, in Orange co. I hunt in orange and rockland co.s

I probably wont get to the range for a while but Im starting to get my loads and ammo components together for next year.

Thanks again.

I use to load hodgen 870, my 7mm rem mag loved that powder, cant buy it any longer as far as i know.It was greatand it didnt cost mucheither. I started using RL 22 and its shoots great to. I cant remember off hand how many grains I use as im at work and my book is at home.

It's quite simple why you find no loads for the 7 Mag. using IMR 4064-that powder is too fast for the big case. I suppose you could use light loads of it in the 7 Mag., but it doesn't fill up the case very well before you get to maximum, so accuracy might not be too good.

Actually my book has a 150 and a 175gr load for 4064. Just no 160. I agree ,though its probably not the most appropriate powder for a large case.

IMR 7828 OR H1000?
