Hello and thanks fr looking, I bought myself a Christmas present. I've been eye-balling a 7.5” Single Seven Ruger in 327 Federal for a few months at my little shop down the road. I gave in to my baser side and it lives with me now. I love my wife. She understands these things. Anyway this thing looks like it's going to be a shooter. I'm getting 2” groups off hand when I get it together at 25 paces. I got American Eagle 100 grainers to try it out. Today I shot up a fist full of .32 acp in it and that was just a hoot. No recoil to speak of and the accuracy was just as good as the full power stuff. I do have to be careful with my grip using the snappy rounds. The trigger guard will bight my knuckle if I don't be attentive. Been shopping in my head for a nice four or five cavity mold. I want a plain based bullet between 100 and 140 grains. I see some on Accurate molds of 115 to 135 that have the short nose needed for this cylinder. I slugged the cylinder throats and got .315 on most and .3145 on a couple. The forcing cone took the same slugs with moderate finger pressure. I read that the grooves are supposed to be . 312 but that doesn't matter does it? I guess if I have a question it is will I be okay to shoot .314” bullets? My .315” slugs fit snugly in fired cases. Thanks again, Dane.
One other thing, the .327 case fits my .222 rem bolt face like it was made for it!
