A quote from John Linebaugh, " To DEFINE SAFE: ANY LOAD THAT DOES
NOT EXCEED THE INDUSTRY'S RECOMMENDED MAXIMUM OPERATIONAL PRESSURE.. In the case of the .44 magnum, this is 40,000 CUP. Not to exceed 43,500 ABSOLUTE MAXIMUM.
The Ruger Blackhawks and Bisley models chambered for .45 Colt are approximately 80% as strong as the same Ruger chambered for .44 magnum. This means we can load the .45 Colt to 80% of the pressure of the .44 Magnum round and still maintain the 100% safety level. 80% of 40,000 is 32, 000."
Using that standard and the loads date provided by Mr. Linebagh in this article, 45 Colt is a close rival of 41 and 44 Magnum, but WILL NOT surpass them in performance.
Frontsight, the ballistics that you mentioned surpass that standard, thus are unsafe according to Mr. Linebaugh.
The 41 Magnum shoots a bullet faster, flatter (better accuracy) and deeper than a 45 Colt. The only advantage the Colt has is in heavier bullets, 300 grains and above. This is due to the lack of development, because of the lack of interest in the 41 Magnum. Same gun and same bullet weight, it's 41 Magnum all the way. Anyone disagree with that, show me the published load data. Apples to apples comparison.
