Here is a ton of 204 reload data.

I have tried reloading for my Encore but I am unable to get the same ballistics that the factory ammo provides with the 32 grain bullets.
When I load up the high end of the combinations on the above page I get pressure issues and I don't get the accuracy of the factory ammo.
I have settled on 29 grains of benchmark with the remington 7 1/2 primer. I tried a little over 29 grains of W748 but it was too much and not accurate from my encore barrel.
The Remington 7 1/2 primers are slightly thicker primers and they hold up better under the pressures generated. I have found softer primers crater. I have not pierced any but others have with the softer primers.
I am sticking with the 32 grain bullets because I like the 300 yard laser beam effect they give.
Anybody tried the 30 grain bergers?
