Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thank you Mike! I screwed up though. Just noticed the COAL I gave was 3.10. It should've been 3.16. Sorry!
Not sure how much of a difference it makes, but can you please re-run at 3.16? Thanks again!

It makes some difference.

Where in the world did you find some Re26???? I have been searching high and low and have been unable to locate it. I am also searching for Re16. I sent an inquiry to Alliant, but have not heard back from them yet.
Take care

I picked up a couple of pounds when it appeared briefly here in Canada. I note that it is now "on order" from most suppliers. Guess I hit it just right.

Graf and sons had some this past week. I ordered 2 pounds of it

Thanks again Mike!

On a side note, looks like I may need to try out some AR2218. A 115 gr Ballistic Tip at 3547 fps!!! Holy cow!! My current pet load using RL-25 launches them at a skosh over 3400 and they're absolutely the surest killer of any cartridge/bullet combo I've ever used. An extra 150 fps would be fun.

May be hard to find this side of the pond.
