Well, some of you have seen posts from oli700 about his Lee Precision 1-oz slugs that he casts himself. He really got my interest so we got to talking and he agreed to loan me his mould and some wads and overshot cards to make some of my own so I could try them out.
Lemme tell you, oli developed this load himself from published data but he thought he could improve on the results as published and he has nailed it!
Yesterday I cast up 55 of the slugs on my front porch. It took less than an hour.
And this morning I put the MEC 650 to work making some finished rounds using the wads and overshot cards he supplied me with. It took no time at all and the crimps came out looking really good.
So outside I went with my 20" 590 and a chronograph to try these bad boys out. And the chronograph results were simply stunning! My first shot over the sensors was
Shooting it was just about perfect. Pretty stout, but not objectionable at all. Then I fired a second of oli's slug recipe. I couldn't believe it. That passed over the sensors at
Yep. One freakin' foot-per-second diference from shot to shot! That is 0.0007318% of variance folks. Anyybody who does this probably knows that if you get inside of 1% on any ammunition velocity you're doing really good. In other words, for a 3,000-fps rifle round a 30-fps standard deviation is right at 1% and oftentimes the extreme spread might get into 50-60- fps.
I've never seen a one-foot extreme spread (granted it was just two shots that I measured).
My results might vary from you own, but I'm going to say that oli really came up with one hell of a load if you shotshell reloaders want to give it a try.
Thank You, oli700 for the chance to give your ideas a shot (pun intended)!!!!!!!
