Advice on 45 Load Optimization

First topic message reminder :

Hi All,

I am going to try to find the most accurate bullet for my 45 bullseye pistol. Can you guys give me advice on how to logically approach this?  Are thier factors which play the most important roles in an accurate load for a given pistol....like the bullet. And then factors which have little, but some impact, i.e. crimp?

This is my thinking

Start with 4.0 gr bullseye - Load 185 swcjhp, 200 gr swc, 185 jhp from Roze  - Any other bullets that can be suggested?
Find best bullet
Change the powder and try 231, N310, bullseye, tightgroup
Find best powder
Once best powder is found play with the charge strength - try a few different gr loads
Find the best load
Next play with OAL and crimp

Any advice?

Best,

Joe

Sure, I think that I may also have a barrel tester.

How do you load pics here ?

Hi All,

After testing 9 different bullets in 45 the best was the Zero 200 gr LSWC and the 185 LSWC (~2 inches - 10 shot group at 50 yards with Ransom).  Better that the Zero and Nozler 185 jacketed and Zero 185 LSWCHP, which was a surprise - but not by much. All the cast bullets from different manufactures did far worse (4-7 inches) than swaged, at least out of my 1911.

I would assume that I would start with those 2 bullets and try a load escalation.  I used 4.2 bullseye.  I see from the previous posts that you gave me a range of bullseye to try?  I also have N310 and hp38 to try.  This is what I was thinking...

both 185 and 200
Bullseye - 4.0, 4.2, 4.4
N310 - 3.6, 3.8, 4.0
HP38 - 4.4, 4.6, 4.8

Best,

Joe
