I'm using 91grs rl-15 behind the 500gr. hornady or woodleigh.
About 10 grs. dacron--sounds like a lot but it's a big case to try to fill.
This keeps the pressure about the same as the normal 480gr. load with 95grs. of rl-15.
I've not chrony'd these yet, and I imagine they are on the slow end, but with this shell, there is so much energy to go around, you won't miss any in actual practice or on game.
I'm afraid to change, because this is what it does well with.
NOW-I must admit, that it is a slight gamble with the pedersolis---I was lucky, and I'm sure there are some lemons out there, but despite what everyone may say to the contrary-it IS worth the gamble.
I did it, and I'm no better at this than anyone else, so obviously it can be done well by anyone.
There is one item I must bring into this, and it is one of bore dia.
The pedersolis have varying bore size-and one must NEVER-EVER use mono-bullets in them.
It is a slight difference, and I have used both solids and softs from woodleigh and hornady, but NEVER use any other mono-anything. Your bore might be too tight.
Actually this goes for all doubles, BUT the pedersolis especially, because they must have a worn out rifling button at the factory. They are nice bores, but the two can vary in size slightly.
This has not effected my accuracy, but to be safe, just shoot woodleighs and hornadys.
Also, when I recieved my gun new, there was a fair amount I had to do to make it respectable. The stock was refinished in english red, and all of the metal was gone over with a fine tooth comb and the checkering was recut to a flat-cut english style, as the factory cut was too sharp for me.
Seriously, there is a lot of work ahead of you when getting a new one, and it's not something to be taken lightly. But when done, and they regulate well, they are a peach.
But, as for mine, I would take it for a big bull elephant without the slightest degree of un-certainty.
Forgot to add, this is with fed.215 primers and bertram brass.
I think I must add also, that I never exceeded the conversion ratio from cordite to rl-15, and I see no need in doing so with the pedersoli. Instead, try different bullets, and like the 500's in mine, if they start settling in good on target, fine tune, and leave alone.
the 480's were erratic in mine and never wanted to settle in on target. I switched to the 500's and reduced charge and they blew my mind when grouping.
But, not every pedersoli is the same. Some will like 480's I'm sure.
I thought I must add that, for anyone turning there nose up at a pedersoli, that the most fantastic shot I've made with it so far was a 100yd. running shot offhand on a whitetail, taking him through the shoulders while he was in full throttle. I personally hate running shots, but I think this says something for the gun and it's performance.
