QL info RL 23 264WM

[hunter24605]

So a buddy gave me 1/2 pound of RL-23..It never really piqued my interest before, but free is free! I want to try it in my 264 WM 24" barrel and 130gr AccuBond..I've looked in all my books and at Alliant and bullet makers sites and really can't find anything.
Thanks!

Thank You!

I am trying to learn the QL stuff, since the disc is on order. Correct me if I am wrong, is the best OBT between 60.82 and 62.11 grains? I made that assumption by looking on OBT on Node #7 as 1.4343. Do you keep crunching the powder chrages on QL until the numbers closely matches between the above chart and the OBT chart with the 7 Nodes? Correct me if I am wrong, thanks

You need to get the real chrono speeds then put that back into QL. Once you've got the real numbers then referencing the OBT nodes seems like a great place to work from.
