Probably beating a dead horse here but I have searched 6 ways to Sunday and cant find an answer, where I live shotshell components are almost non existent but I finally managed to put together everything listed in Hodgdon's manual for the hulls I had. I have read many posts (with imperical data to prove the contention)stating that exchanging a 1 oz slug for 1 oz shot payload will result in lower pressures, using that rational it would seem that subbing 1 oz for 1.1/8 oz would have correspondingly lower pressures than a 1 for 1 swap. So I am very comfortable doing this but dont want to end up with slug loads that are to anemic.
Here is a list of the components I have, and I'll note the loads Hodgdon has for a 1.1/8 oz shot load;
HULL - Remington Premier STS (once fired
WAD - Winchester AA12
POWDER - Clay's
PRIMER - Winchester 209
SLUG - LEE 1 oz
In my Hodgdon's manual they list all these components for 1.1/8 oz shot with three different loads, I'll list these along with pressure and velocity as shown in the manual;
1090 FPS - 16.2 grains Clay's @ 8,100 PSI
1145 FPS - 17.3 grains Clay's @ 9,700 PSI
1200 FPS - 18.4 grains Clay's @ 11,300 PSI
I have to use one of these loads and substitute the lighter 1 oz LEE slug, which should I use? I dont need full bore high end loads and would like to stick somewhere in the middle, as longest range I would ever use these would be 100 yards. Would the 17.3 grain load get me where I want to be? Or would that end up bein a much lighter load because the payload is 1/8 oz lighter? If that is the case should I just go with the 18.4 to hit my middle of the road target?
Thanks in advance.
