Home Forums Reloading Big Game Rifles Reloader 26 in 7mm Rem Mag

When I did have one I saw 3100 fps with H1000 but that was long ago.

Please be advised. This is only a simulation, although I have found it to be very accurate in most applications! YMMV

I have worked up with 3 powders in this group and just did a comparison for velocities generated on my Oehler 35P in a Model 70 with 26" barrel. Using Federal 215 primers, my results were:

Quickload
72.3gn H 1000 = 3149fps
67.9gn Rel 22 = 3148fps
73.7gn Retumbo = 3111fps

My loads Chronographed
73gn H 1000 = 3011fps
67gn Rel 22 = 3134fps
73gn Retumbo = 3057fps.

Interestingly, my Rel 22 load averaged .602" during testing. The Aussie powders were 1.5 - 2.5" by comparison.

AGW: Interesting.

I've found RL22 to give good accuracy as well.

Fotis-

Thank you very much. Your predicted speeds are very close to what I measured.

I've got to get that software.

Thanks again-

Judd

it is priceless!

I'm pretty sure if you put the quickload data between [code][/code] it'll show up on the 'fire as much more reader friendly.

much better in code

Hello guys!

I'm new in this forum but I've been reading your posts for some time and I was wondering if any of you could run the QL so I can have an idea of how this powder (Reloder 26) works on a 7mm rem mag with 24" barrel, using hornady sst 154 gn and hornady sst 139 gn with federal 215M primers...
Thanks

Another +1 for RL-26. Tried it last weekend for the first time in my 7mm WSM with 162 A-Max bullets. Really good accuracy! Loading up a bunch more and will bring the chrono next time.

Try some Re33, also. Works great with 160s and long barrels.

Bob,

I got some Vv N-570 to try in my 26 Nos, hearing it was a good one for that round. I saw a QL print out that showed it as top performer in the .300 Win Mag with 200 gr. bullets.

It's a real coarse stick, just about won't work in a powder measure. I had to remove the RCBS Uniflow drop tube, stacking was so bad. I drop a charge without drop tube in my scale pan, adjust to weight, then funnel into the case.

It's a high energy powder and doesn't over fill the case, at least the Nos. Haven't dropped a load in either .300 Win Mag or 7RM.

RL-33 is a favorite among some LR .264 WM shooters with 140's.

DF

I just scooped 65lbs of '26. I'm banking on it working good lol

You better hope it works...

If I can find some of the stuff I wanna try it in the 7mm Mashburn with 175's. My rifle does well with H1000 and 175 PT's at 3050, but it seems like RL33 might free up a little speed. It is hard to mess too much with the current load as it shoots really well, but I can't resist giving it a whirl..



Retumbo looked pretty good as well, but around me, RL33 seems to be easier to locate.

Scotty: Not shabby....





Dirtfarmer: Those VVN powders are the beotch to locate around here....

I tend to stick with the local available stuff and am ready to try some of the new Enduron 7977 in the 7 Rem Mag. Bought 2 pounds.

Powder Valley had 570.

That V570 is some awesome looking powder in most of the QL profiles for the big jugged 7's. If I saw it locally, I'd bite the bullet and HAVE to grab a pound..
