As we all know, powders like H110, Li'l Gun, W296, and such, are pretty much non-existant right now, and data for 300 MP in the .45 colt is hard to find also. But I can at least find 300 MP. So...
Here is what I came up with:
280 (actual 285gr) Accurate RNFPGC. .4525
25.0 300MP CCI 350 (I started at 23.5)
Starline Cases.
BAC lube.
Temp. 87* Hum.79% Overcast.
Competition Electronics Pro-Chrono.
1680 avg. fps @15' with an es of 20fps over 5 rounds!
No sticky extraction or overly flattened primers, or any other unusual signs, can't really tell about leading right now as the barrel is soaking with some Hoppes in it right now, will know more when I run the patches through. I fired a total of 30 rounds of different loads.
If I am out hunting deer and piggies, and I happen across a bear, I don't think I will have any worries as far as power goes.
I don't know how this load shoots for accuracy yet, will have to get to the longer range, but if the es is any indication it should do pretty good.
Recoil was stiff, but smooth, I knew I was shooting a strong load but it was a "slow" kick.
A 255gr boolit with 8.2gr of Tin Star @ 1040fps felt like a bb gun in comparison.
I also tested an Accurate 255 RNFPGC with the 25.0 charge of 300MP, they were running in the 1790's, but I only had two rounds of those, and I think at this point that the 300MP is better for heavier boolits.
