Thread: Which powder 300 saum rl17 or rl26

Anyone have quick load etc ?

Trying to work out what powder i should try, or maybe use both and physically see which is better ?

Running 178gr eldx, I cant fit upto 67gr of rl17 in the case with the projectile seated. Barrel is 18 inch carbon.

I know that load is way too high, but im just stating what i can fit.

apparently 61.5gr of rl17 will get me 2828fps and 68.5 rl26 will get me 2905fps. Both apparently just below absolute max ( just using as a direction of which powder to go for ) , case would be about 80% full on rl17 at that charge and the rl26 would be 100%.
