Thread: Cast loads in 30-30

Great data man. Thanks that's going to be useful going forward. My barrel is an inch shorter than yours so I'm interested to see what my speeds are. Cheers

Good results there, personally I'm not a fan of trailboss, it has its uses but you seem to get some wide variations in speed with it. Admittedly I've never chased subsonic loads but the 14 to 1600fps region is where I "aim" for. You might like to consider a light charge of a shotgun or pistol powder if you are after better. Most cast bullet shooters will probably say if asked for a starting load in any calibre 10 grains of unique or equivalent ap70n

You are right Trail Boss may not be the best powder for sub sonic loads But it is the easiest to get good results with, powders like Red dot AS30 N310 and other fast pistol / shot gun powders
can give better accuracy but are a lot harder to work with needing fillers to keep the small amount of powder against the flash hole, Trail Boss does not need that much fussing about wth,
Another good load besides 10 grs Unique is 13 grs Red Dot if you Google The Load it will pop up,
.30 cal cast bullets generally have their best accuracy between 1800 and 1900 fps using the soft lead that I use or wheel weights any harder won't expand or will shatter.

Truth be told I used to use fillers but stopped years ago, never have had a problem with ignition or consistent velocity. Only thing I still fill for is light loads in black powder numbers and I've discovered rolled oats to be about the best,
