45 Auto 200 gr Speer LSWC OAL 1.19" Bullseye Max 4.6 gr (807 fps)
Lyman #49 lists these as potentially most accurate loads:biogenic said:200swc ... My Lyman 45h edition has 3.5grain as the most "accurate" load
200 gr CAST LSWC W231/HP-38 OAL 1.225" Start 4.4 gr (771 fps) 11,000 CUP - Max 5.6 gr (914 fps) 16,900 CUP
5.9 might be getting a little energetic!
Alliant shows MAX loads of 4.6 with lead bullets and 5.8 with jacketed bullets.
What kind of bullets are you using??

Like I said in post #13.example lyman lists a starting load of 4.9 and alliant's data shows a max load of less than 4.9
Alliant data is for soft-swaged Speer bullets.Current Alliant data is for Speer soft swaged bullets.
Your cast bullets will take more pressure & velocity.
