I'm just starting to reload the 375 HH in the Encore pistol, a 375 HH cartridge has an OAL of 3.6, pushing an unprimed shell and bullet into the breech until it touches, and using both a Barnes banded solid and a Barnes TSX, I'm getting numbers like 3.830 and 3.850. Does this sound right, and doesn't a .25 jump seem like alot if using the standard OAl of 3.6?

in single shots especialy tc's load them to fit they chamber or as long as you can keep them in the neck.tc,s usually have long throats.that 375 is gonna be a handful.
