Powder for 7mm Rem Mag

[idaho elk hunter]

62.5gr IMR 4350 CCI250, I used to use this load with the Nosler BT. It drives tacks, I don't see any reason that a Partition wouldn't shoot very well with it either.

One powder doesn't necessarily group better than another, it's your recipe, Combo of bullet, powder, primer, cases, seating depth all working together

RL22 is one of the best powders I ever used in my 7mag, I never had any issues at all regardless of temp. H1000 likes a heavier bullet than 150s, 160gr -190gr it pretty well out paces most others with the major exception being Retumbo, Ramshot magnum, and supreme 780 also look pretty good on paper but I've yet to try them. If your worried about temp stability the Hodgdon Extreme powders are the ticket, H4831 being a very very good powder for most bullet weights.

+1 ,,,drilled it perfectly.. well said..no one can give better advise than this

IMR4831 is what I use. Pushes 162's at 3050fps with exceptional accuracy. I found a load with H4831SC that's about as good just uses more powder.

Haven't tried the powders you have so it might not be much help to you.

How much powder are you using to get to that 3050? Just curious, what charge did you start with?

Mkyle,

You may get someone else that utilizes this load to pipe up for an answer, but chucknbach hasn't even been on this site (hasn't visited) for two and a half years or so.

VV565 is usually available and very accurate for me. I like it

another vote for H4831SC.

My vote also goes to H4831. My 7mag shoots 145lrx into a dot, and H4831 does it so consistently.
When I play with 168"s, I use H1000, also a great powder, but really shines with heavies. For what it's worth. I use standard, (WLR), primers, and it cuts ES, and SD to single digits. Again, I'll second elkaholic, and my vote is H4831.

 

[zerosprk]

Mine really likes H4831SC and a 168gr. Berger VLD. Critters on the other hand don't like it all...

With all these new powders, people overlook the older ones. RL22 does amazing with the 7mm.

It does. The problem is it's difficult to get many of the older powders. And expensive.
