I'm sure some one here has "Been there, done that" I'm trying to find a powder that will
<UL TYPE=SQUARE><LI>Fill a 7 MM Remington Magnum case to the shoulder.
<LI>Push a 162 grain AMax bullet at 3000+ FPS out of a 26" barrel.
<LI>Preferably not a temperature sensitive powder[/list]

I've been playing with some RL25 this morning. It doesn't quite fill the case as full as I'd like it, but it is pushing the bullet out at a 3126 Ave speed. Right now, I'm just playing with the seating depth. But the last two three shot groups have had 2 holes nearly touching, and the third hole several inches high. ( 300 yards ) The thermometer said 82 degrees as I came in to write this. Is it already getting to warm to use this powder? Or could something else be causing me the flyers?

Tim,
I would give H1000 a try, it's less temperature sensitive and I think the burn rate is close to or maybe slightly slower than RL25. Maybe someone else out there can comment on this. Take care, the WCC872 should be here by friday.

Wayne,

That sounds pretty good, let me know if it does. There is a gun show ( I think ) up there on Saturday. If so, I'm planning on going. If you'll be around, I'll meet up with you before or after to pick it up.

in my 7 rem mag pushing 162's, i've had great luck w/ 70 grains of rl-25 (this is a max load)...this load fills the case fairly well (win), and gets around 3050 f/s in my 24" rifle.

as for temperature sensitivity... i do most of my serious load testing in the summer (typically in the 90's), then verify its quality before deer season (temps typically in the 40's or lower). for the most part, rl-25 does pretty well...accuracy remains, velocity is acceptable...

i've been curious about retumbo, so if anybody has first-hand accounts w/ it, i'd like to hear about it...

dakotasin,

I used 68 grains of Retumbo to push the 175 Noslers at 2864.

I shot a three shot group under an inch at three hundred yards, then ran out of powder.


I'm hoping to find some more this coming weekend.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
