Hi,
I have a 243 AI project with a pac nor 26' barel that I am trying to get max velocity from with 105 Bergers
Anyone got any ideas? Tried RE 22 46.5 grs started showing pressure.
Looking at RE 25 or anything else that might work. Trying 47 grs of RE 25 this weekend.
Please give me your thoughts.

My chrono croaked a few years ago and without one it is just a guesing game. I've had to go out shooting with chrono owner friends.

I have the .243 rem with 26 inch using Winchester cases. I have been using winchester Large rifle primers never mag primers. IMR 7828 SCut powder It takes about 1.5 grain more than R-22 to get the same pressure, but my average speed went up 34 fps with speer 105 home moly coated.

I got away from 105's and now I'm focused on Nosler 100 BT's Hodgdon H 100V seems promising
 
I am shooting 50.5 gr. H-1000 and 105 bergers. Velocity is 3170 and no pressure signs. Don't know if this is max velocity. I suppose it isn't. This load shoots so well in my gun that I looked no farther. Have shot several 5" groups at 985 yds.
 
51 Grains Retumbo works well in mine for a velocicty around 3250 with a Fed 215 out of a 26 3/4" Broughton. I have just recently started shooting 52 grains of Magnum at 3280. Both are warm but I have several reloads on the cases.
