R19 and the other powders you mentioned. Hope this helps. RL26 was definitely the fastest in my rifle.

beretzs,

Thanks for the information. Is this data from Quickloads?

Yes sir. Sure is.

With the Swift 53 grains might be pretty hot. With 130 Bergers I was getting flat primers at 52.5 in hot weather. Dropped back to 51 grains and still getting 2950+/- fps.

Berger tops out at 50.6 for the 135 elite.

I agree with that. My current lot of 26 is pretty quick. As always, work up from low until you know where you’re at with the data.

Beretzs

Please forgive my 'butchering' of your larger charts post. The following 'excerpt' compares quite well with my load.....

My load in my rifle is 49 grs yields 2987 fps with a 10 gr lighter bullet

We are using different rifles and components yet the results are 'comparatively' close.
I've shot the 'same' cases repeatedly, the case stretch is minimal, and primer pockets are tight.

THANK you for posting ALL that info.

Sorry, I forgot. Recently I bought some Rl 26 but have not yet started testing it.
It'll be Spring before I do because my deer season starts in earnest Saturday.
