This was another bullet I wanted to make since I had the cases ready to go from about five years ago.
From my initial testing I found that the cases needed to be trimmed to 0.800" to get a better overall finished length.
With a 3/4-E point profile the 300/gr bullets come out about 0.090" longer than a factory bullet.
When seated around 1.580" and a light taper crimp the finished round for my cost will be less than the cost of a primer today.
I usually load these with 30/gr of IMR 4227 and used this weight to load the dummy round.
This will also result in a slightly compressed load which usually is more desirable for a more consistent round.
Without a powder charge or filler, the bullet just can't be seated because it will drop into the case when seated.
No case belling is needed for seating the bullet due to the base of the 45/acp case not expanding to 0.500"
I based the core weight on using Blazer 45/acp cases. This would give me a finished weight on average of 300/gr +/- 1/gr.
Federal cases were very close, but Winchester cases could be almost -8/gr light.
Even weighing the Blazer cases they could be several grains heavier or lighter from the average weight.
There is just to many variables involved to get within +/- 0.5/gr even with swaging the cores.
With a 300/gr bullet I really don't think several grains heavier or lighter will affect their accuracy.
If I were making match bullets for distance then everything would be within 0.05/gr or better, but I'm not making match pistol bullets.
The pictures will just show the various stages required to make a finished bullet.
