so did some figuring on using the Lee C309-185 boolit in my 30-30 and be able to have the crimp grove at the end of the case.

the standard 30-30 case is 2.039" long

now to seat the bullet deep enough to keep it off the rifling i need to trim the case back to 1.900" to have it at the crimp grove

would taking .139" off the case length be ok to seat the bullet deep enough into the 30-30 case with the case neck end at the crimp grove be ok?

the bullet will end up being a bit past the neck and into the larger portion of the case but i also noticed this bullet will be that way in 30-06 and other cases. would this cause issues for me? i think in the 30-30 the gas check would be a tad past the neck if this makes sense.

seat your bullet with the grove inside the neck , it wont hurt a thing , , do not cut your cases , this will cause some slight accuracy issues , the loaded ammunition may not seat true in the chamber.just make sure the overall length will fit you rifle and the load ( powder charge ) is good for your bullet weight per your reloading manual for cast bullets..

You can trim your cases like that and it will work. Since case trimming is something I don't like I would either seat deeper as Badbob suggested or use a different bullet. You may well be using a lever action and want to crimp in the groove for that reason, so they will hold up in the magazine tube without telescoping. Hornady uses short cases with some of their loads to accomplish just what you are suggesting.

Your gun your bullets. Try 3 of each. Trim three cases and three deep seated. See what works best. Might be a non issue. As long as the lead doesn't seat below the shoulder you should be good to go.

It's way easier to buy a Lee collet crimp die, and make a groove wherever you want.

Trim your brass to fit your chamber only - for other problems look for other solutions.

People have been doing this for years and it works just fine. Accuracy will not be affected.

The main problem for me with trimming to fit the bullet would be winding up with several different case lengths to keep sorted.
The Lee collet crimp would be easier to live with unless I only had one bullet that I would ever use in that cartridge.
Take your pick.

I am with this! Beyond that, find a different boolit. To have odd case lengths floating around would needlessly complicate things.

You can go the other way but that is my take on your situation.

Plus make sure it will feed from the tube mag. Load some 30-30 this spring, had not done that in years. Found OAL by chambering, forgot about feeding from the magazine. One of those DOH moments. Had to single feed at the range that day.
