Home Forums Hunting & Shooting Ask The Gunwriters 1 powder for 3 calibers

HuntnShoot,

Good find! I actually have a paper copy of that data, but didn't check it.

It is a good reference for a lot of stuff, but especially reduced loads. Though I doubt many 7mm Remington Magnum handloaders are going to be satisfied with 3180 fps with 120-grain bullets or 2555 with 175's, either of which can be easily accomplished in the 7mm-08.

I use big game in my 06 and 6.5CM.
But not sure how big game would do in the 7mm magnum.
He wants one and done. So He’ll just have to shoot the heavies in 708 and 06 with hunter.

MD i have several old load books from IMR that have loads for almost all of their powders.

Sometime the free stuff pays off,I save all of the older load books because one never knows.

Great--but again, I doubt many 7mm Remington Magnum handloaders are going to be satisfied with 3180 fps with 120-grain bullets or 2555 with 175's, either of which can be easily accomplished in the 7mm-08.

I still have about 8 pounds of IMR4350, but am trying H4350 and IMR4451 in rifles. It seems that accuracy is very similar. I forget which is the most dense, but if I’m loading 100% fill, the weight is different between the three.
My 257 liked IMR4350 behind 85 grain Combined Technology bullets.
But with the same accuracy and higher velocity RE15 Is looking pretty good.

I pick Varget. It covers about every cartidge from 30-30 to 7mm Rem Mag. The limitations are that it doesn't work with all different bullet weights in every caliber but it has data for more cartridges than any other powder. Hodgdon lists data for 90 different cartridges from .17 Rem to .50-140 Sharps.

Just wish I could find it more often. Usually out of stock. Always buy some when available.

Edit: Hybrid 100V is almost always available and appears to be a good performer in all three of the OP's chosen cartridges in bullet weights that are typical. Supposed to be in between 4350 and 4831. I have been thinking about this one as an alternative to all the more popular powders that can't be found when you need them.

UncleAlps,

I just looked up Hodgdon's load data for Varget. The heaviest bullet they list Varget for is 130 grains, with a maximum velocity of just about 3000 fps.

This is just about what can be obtained with 130s in the 7mm-08--which once again (as with the guy who suggested IMR3031 as one powder for all three rounds) begs the question: Why would somebody looking for one powder to use in the 7mm-08, .30-06 and 7mm Remington Magnum use a powder that turns his 7mm Remington Magnum into a 7mm-08?

Mule Deer,

I agree that making all three rounds work well with the same powder is constrained with compromises. If I were to buy one 8# jug to keep on the shelf in case nothing else was to be found for a long time it would be Varget for me.

The Hybrid 100V data looked somewhat better than Varget for the 7mm RM though. What are your thoughts on it?

I would choose this.

H4350 or W760
