Imr 7977 in the magnums

[dmorin]

Anybody try this powder yet lookin to use it in my 300WSM and maybe my 338 Win mag and maybe the 26 Nosler

I tried it with 7 mm rem magnum. I was shooting 150 gr accubond long range bullets. I had some sub moa groups but nothing 1/2 moa. I think the velocity was around 3050 if I recall correctly.

I was thinking about trying it in my .338LM. But I got a deal on a lot of Retumbo. I may in the future look at it. It shows a bit slower than Retumbo, but the cost is attractive.

I see Hodgdon only lists 7977 with the 300 wsm in the 200 grain and up bullet weights so that may be a non-starter for you if you want to shoot lighter bullets.
They also list only 250 grain bullet and up data for the 338 win mag so that again may be a non-starter for you depending on what you have in mind for bullet weight.
Velocities look to be very similar for 7828 in those calibers.

I Would be cool with splitting a lb with someone in zone 222 just so i could spin up a recipe for my over bore.
