I've used RL25, Retumbo and IMR7828. Didn't know they made a RL26.

Hmmmm, hundreds of rifles at $350 a pop... If you want to supply me with projectiles, I can quit my job and just start doing load development at 500' ASL for yall. Split the profits 75/25...And all you got to do is supply the bullets.

Well, I don't have any RL 26, and it appears that no one else does, either.

Hmmm, Most of loads have been in our own or others for testing. Someday maybe we will have a deal.
Right now headed out to shoot one of those test loads on a new bullet.Steve

Should have said loads not rifles.

The 7rum is tough as hell on bullets... I wouldn't use a "hunting" match bullet in one. You WILL have accuracy issues as the bullet is too stressed by the chambering...
What bullets have you used???
your powder choices are decent; if the rifle has shot one load well and everything's fine on the rifle, it seems to me a crappy bullet choice was made....

Just received a note from a customer yesterday about his 7rum and our 143g Hammer Hunter. He is running RL-26 and worked up to find pressure at 3760fps. This is, in my opinion, truly unlocking the designed potential of the 7rum.
At 1000ft elev and standard atmosphere this gives a 400y zero for max point blank range of 465y. It will carry 1800fps to 1125y. At 800y impact vel would be 2300fsp with only 7.5 moa of drop and 7.5 moa of drift with a full value 10mph wind. At 800y still has 1665ft/lbs of energy. An arbitrary figure but good to know. (Whole other subject) All of these figures will only get better with added elevation.
Now the 7rum is the long range laser beam it was designed and marketed to be. You can lob them into 800y or get them there on a rope.

Hi TwoMore, did you ever settle on a load?
