Home Forums Reloading Big Game Rifles RL-26

Anybody load this powder in the .300 Win. mag. with 180's?
Velocity swings at various temperatures? How about accuracy, velocity, and lot consistency?
Thank you,
Jim

Jim,

Check out Mule Deer's posts regarding RL-26 and the 270 Win, in the "Ask the gun writers" forum. He started testing for temperature sensitivity last year, through the winter (even in zero temp ranges) and also in the summer. Throughout he has recorded consistent velocities. As to the 300 Win Mag, I don't recall if his tests included it, but there were many guys posting in that thread that were using many other calibers. I'll post a couple of the threads below.

This one is specifically related to cold weather testing. https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/11644886/1

I have found it to be very consistent and accurate in my 270 with 150 gr partitions and 130 gr E-tips (dime size groups and less) - and 7mm-08 with 150 gr Balistic tips. Many are finding that RL-26 seems to have a niche with heavy for caliber bullets - good accuracy with excellent velocity. So far, I am very pleased with what I have seen in my rifles with RL-26.

Thank you've very much! Will check out what they have to say. I have a good load using H-1000, but always interested in other components.

I tried RL26 in three different rifles 257 Roberts, 270 Winchester, and 7MM Remington mag.
It gave the highest velocities in all three rifles. But was not as accurate as some other powders in
all the rifles. RL17, Norma MRP, RL22 were more accurate in 257 Roberts with heavy bullets.
Norma MRP was the most accurate in the 270 Win, RL26 was more or less tied with several other
powders for accuracy, Superformance, RL23, RL17. In the 7MM mag, Retumbo was the most
accurate, followed by MRP, H1000, and RL22.
