After reading tons of stuff and watching Wade’s videos I tried some 2.75 fiocchi hulls someone had given me. First off I like these better than the federal. I tried these below
Longshot powder
Fiocchi 2.75 hull from a 1 ounce dove load
Ctps wad trimmed for 2.75 loading slit four times half way down the wad
12 .310 hand cast buck I mixed some pure with ww I stacked these by twos and covered in bpi original
Remington 870 28 inch barrel factory full and modified choke
I tried 27,28,29 charge weights
The modified did ok and I tried two loads without buffer both with 28 grain charge and with both chokes, both of these did ok but opened up a bit plus when inspecting the wads it looked like the pellets deformed the base pretty bad from setback I assume
The best I had was the 27 charge all shots were between 30 to 35 yards
Tried to upload the picture from my phone but won’t allow it for som reason you could cover all twelve pellets with a closed fist
