7MM Rem Mag, Powder & Die

[John O]

Highly recommend IMR7828. When I go 3/4 between low and max, I have found good results on 139, 140, 154, and 162 gr bullets. Easy to find, and matches the 7mm RM very well for burn rate.

ctracingraptor, I highly recommend the Redding competition bullet seater dies. They have a collet that closes and aligns the bullet to the neck before it is seated. If you can borrow a runout gage and check the runout on bullets you have loaded with regular RCBS or even regular Redding seating dies you will see the variation in runout can be as much as .005 in. Accurate loads should be 0.001 or less. The competition seater dies will dramatically reduce the number of flyers in for groups

IMR 7828 is a good place to start, plus it's usually easy to find

Yeah that's kinda the direction I'm going to head, i do like that Redding has the Master Hunter die set, you get the competition seating die, and the full length sizing die. I think thats the route im going to end up going.

i dont know how you guys do it, but my shoulder does not like ladder testing, i really needs a muzzle break lol

Two words...."lead sled"

 

I true ladder test should take most of the day

My ladder tests usually take 4 hours or so for 12-20 rounds. I shoot them at 600 yards, so walking back and forth can be ridiculous. We use a method I would never suggest for marking each individual hole after the shot. A radio and a safe staging point are needed.

I like to walk back and forth. Mostly because it forces me to let the barrel cool.
