Thank you all for the info and advise..............

I will save the 231 for the 115gr where it works out.......and try all my other powders for the 1150 fps factory load.
I have been slowly working my way up in fps and OAL to get to the higher fps. Hoping to find a Fac. Dup. in the minimum length and also the maximum length for the 124gr PRN bullet.

Have loaded 85 bullets so far out of a 500 box...... 5 at a time. When I get it dialed in I will try a 10 group in the finals for the best loads so the fps has a better average.

With a 4" barrel 4.5grs of w231 at 1097 fps was not a bad shooting load and had a ES of only 19.

Have a great day.
