Reloader 22

[FullDraw]

I'm new to reloading I have all the gear I need now, I have been looking at the the Speer manual data for 300 mag and 30-06 as I will be loading for these 2 cal's. Reloader 22 looks like a good powder choice for these 2 cals. It does not produce the highest speed but it's in the top 3 for sure. The question I have is this a good powder to start with? I will be using Speer Grand Slam 180 grain bullets not sure about primers are CCI good?

Their fine, I like Federal Match, and your gonna need mag primers for the 300

I switched from Federal Match to CCI match this year, the Federals were not setting off the RL 22 consistantly. RL22 is an excellent powder choice for these 2.

I'd probably use RL19 myself nut RL22 will work good, as will H4831, IMR 4831

I've also had good results with RL 19 in these two rounds.

I just looked up Reloader 19 speed goes up in the 30-06 but down a bit in the 300 winmag, pressure is up on both cal's with RL19 To me RL19 looks like it will have more knock down force than RL 22, I guess a safe start would be to start my loads at 10% under the RL 19 data posted on the Alliant website.

Reloder 22 is a great powder for the 300, but might be a bit slow for the 30-06, I use H4350 in the 06.

I use RL22

with my 165gr Nos Partitions in my 30-06. Shoot hot dams.....

I use RL19 in my 300 WSM and 180 grain Grandslams, Winchester primers. I get consistent 1/2 inch 3 shot groups at 100 yards use a ruger Frontier with the 16.5 inch barrel

 

[todbartell]

10% has always struck me as being very conservative especially in larger capacity cartridges. 5% (3-4 grains below max) is a good place to start IMO for anything with the capacity of 40 grains or more

I agree that if you want one powder for both cartridges, Reloder 22 is an excellent choice, as is H4831SC, Vihtavuori N560 or IMR 4831.
