Accurate No. 2 .45 data

[eldon519]

Hello,

I'm hoping to cook up some standard-pressure .45 ACP loads with cast 185-gr SWCs to mimic the Corbon 185-gr +P DPX load with a velocity of 1075 fps. I don't have to achieve 1075fps, but I'd like to get close. Would it be reasonable to carefully work up to the jacketed bullet data substituting the lead bullets? Accurate does not list a 185gr cast load for some reason, but I included the 170 and 200 gr max data too.

The Accurate Arms reloading manual includes the following data:
185-gr Nosler JHP
6.7 grains 1,106 fps 20,750psi

170-gr Montana Bullet Company SWC
6.5 grains 1,079 fps 19,400psi

200-gr Lasercast SWC
5.8 grains 939 fps 17,400psi

The COL of the cartridge will have much to do with the start charge. Have you determined a workable COL yet ?

I don't have any technical info to add to this thread,just a Question. Why are you trying to achieve a certain velocity? I personally couldn't care less what velocity a load is as long as it's safe. I always start working up a load with the minimum powder charge listed and work up slowly until I find the most accurate load. Who cares how fast it is if you can't hit anything with it?
