7mm mag powder?

[gonehuntin68]

New at reloading and have done some research on powders. There is just so many of them it's hard to choose. Wanna see what you guys think. Tc venture, 24 inch barrel, 1 and 10 twist.

My Rem 7 mag loves Hodgdon H1000.  I'm sure others will have options as well.

As you said, there are so many powders available for 7RM. Which projectiles are you looking at using? H4831(sc), H1000, Retumbo, IMR 4831, RL22, to name a few, are some of the most popular. Being that you're new to the game, it is best advised to use a good reloading manual (Lyman, Hornady, etc.) and start with the beginning loads and work up. While it is very tempting to use a load that you find posted on the interweb from Billy Bob, don't. Bad things can and do happen. Have fun with it.

I'd trust gas station sushi before some of the reloading advice on HW.

I like Hodgdon powders. For the 7 mag I'd go with either H1000 or H4831.

Powder is in short supply though, so you may have to go with whatever you can get.

I use imr 4831 at 60.4gr at 3000 fps.162 sst bullets.out of a savage 111.This load has proven the most accurate at 100 to 500 yrd's. My best 5 shoot group at 100 is .950.
   This load I found has mild  recoil along the line's of an .06.
   Be advised this is a max load , u should work up to it and look for pressure sign's.
   I use the 162 gr sst because of the bc at 0.550. This bullet will put them down hard!


    my bad,not 1.950 but .950.     helps to use my glass's.....

Norma MRP has been my powder of choice for my 7mag using 140 grain Accubond or Partition.

Now, is that sushi from the old "Jims's Stab-N-Grab" or a legit gas station like AM/PM?

As far as powders go, a good reloading manual will have some recommendations that worked well while they were developing data. A magnum primer and some IMR 4831 is a pretty combo to start with. Just pick a bullet and track down good data from either the powder or bullet manufacturer. Hodgdon had a great online data base that covers Hodgdon, IMR, and Winchester powders.

I'm in favor of Vihtavuori Powders they all appear to be very clean burning.

I'm using IMR 7828 with 168 gr Berger's.

Which is the exact same powder as Reloader 22, so that's nice in that if you can't find one at the store you might find the other.

No, it's not. They are similar but not identical.

This is poor advice at best. Providing information like this to an admitted new reloader is dangerous and bordering on negligent. Unless you have access to the proper equipment or adequate experience to make powder substitutions, it is a poor idea to do so. The OP has neither and I suspect that you don't have the appropriate equipment or technical background to do so either.

[MountainWalk]

Yorke, I would assume the OP  would use r22 with 7rm rl22 data. I may be wrong.
I don't think bobcat was saying use the 22 in place of MRP.
