Not what you asked for, but I believe 7828 is the go to powder in the Seven Mag. Doug “Factio democratica delenda est"

I crammed all the Retumbo I could get under a 150 gr bst and velocity was in the twenty eights . Don't recall how much RL 25 I started with . I only loaded three rounds or so and didn't get a group . Didn't chrono them . Pop , you mind looking at your magic chart for a 270 cal 130 Barnes XXX with muzzle velocity of 3487 . I just re-zeroed at 250 yds this afternoon and I'm wondering what the drop is at 300 and 400 yards . I can't find the B.C. number for them and anyhow my Nosler chart is in even hundred yard increments . Sorry for Hi-Jacking your thread but figged this might be faster than a PM. Never holler whoa or look back in a tight place

.280Rem Campfire Outfitter Joined: Dec 2005 Posts: 13,760 Alabama	I saw somebody on here write that Alliant suggested if there is no available data, start at R-22 max loads and work up. 66grs should be a good starting point. I'd think R-25 should be a good 7mmRM/160 powder. I'm getting 3080fps in a 25.6" bbl with R-22...R-25 should give that or a little more with no problems. War Damn Eagle!

MtnHtr Campfire Outfitter M Joined: Jul 2001 Posts: 8,759	POP, RL25 works too good in the 7RM not to try it. My 7RM will print .25" grps using Fed215s, RL25 under 150grBTs. Velocity is right at 3200fps out of a 25" PN barrel. Start out using the upper end data for RL22 and work up. My load with RL25 is only 2grs more than RL22 and is warm so work up carefully. IME, RL25 is more consistent and accurate with 150-160gr bullets than RL22 in the 7RM. The added velocity is nice too. MtnHtr

I know the data shows 70 gr as max with some 160 gr bullets. The 280 Remington is overbore. The 7 Rem Mag is over bore.

My former best load in my 7mm RM. was 65 grs. of RL 22 with a 160 grain partion. 69 grs. of RL 25 not only fills the case fuller but also is around 75 FPS. faster and a bit more accurate. Both loads shot out of my browning safari with a 24 " shilen barrell. Norma cases, fed. 215 primer.

Mark R Dobrenski Campfire Ranger Joined: Apr 2001 Posts: 28,277 Bozeman, Montana	POP-I like 7828 in the big 7's for bullets in the 140-160 range. It also works very well with the big boy 175's. For the 175's I also like R25. Good luck to ya Dober "True respect starts with the way you treat others, and it is earned over a lifetime of demonstrating kindness, honor and dignity"....Tony Dungy

Best MV AND best accuracy. It isn't energy that kills. It's holes! Dogzapper A fine is a tax for doing wrong, a tax is a fine for doing well
