mini lathe to modify bullets ???

I have need to modify some .375 bullets to flat nose so they can be used in a tubular magazine. Hopefully NP's or Swift's. Mini lathes are too costly for such a small project.

Has anyone found an inexpensive way to do a precise job.

Maybe there is a way you could use a case trimer. I think I can get a cutter for mine to make hollow points. Fuzz

what cal are you loading for? you might want to try using a file trim die after the rounds are loaded. I made up a die once to file the tips off of Hornady 350gr round noses for my 45-70. worked great for that.

I use a drill press, machine vise and an HSS cutter to modify Speer tungsten solids for a .450 alaskan. Put bullet in chuck and set vise as needed then lock one side. Advance the vise very slowly until the cut is finished. I also add a new cannelure in this process. Use only very sharp cutters. Realize that this may reduce the life and accuracy of the drill press.
Also, since I can't find any Swift .458 400 gr flatpoints, I use a band saw with a fine toothed band and cut about 40 grains off of the noses of 450 grain Swifts. I have a small piece of angle iron set into a block of wood that I use to keep things square. Works ok, but is not for volume production. The Swifts are too soft to put in a chuck like the Speers.

Place a 1/2" electric drill in a vise, and use a bastard cut file, mark how much you want to remove, so you take the same amount from each bullet.

I want to thank everyone who got back to me on this. Lots of good advise. FWIW, and considering my limited supply of tools, I ended up putting the the drill in a vise, then using a carbide disk in a Dremel to lop off the end of the bullets. Then fired up the drill at low speed and used a mill file to even and cut down the end to the desired weight. Bullets were 300 gr. .375, both NP and Swift. Was able to get all to weight within about 1/2 gr. ie, 280 gr. Slow work, several times in and out of the chuck to weigh them. But, the job got done.

Thanks guys.

Steve

I may be late to the race but how about if you were to full length re-size them in lube-sizer die and using the press to form (Flatten) the noses of the bullets! I find by changing the nose ppunch I am able to form a RN bullet from a pointed bullet quite easily, these being cast bullet and in 45/70 but see no reason why it would not work on the jackedted 375 bullets if you have a strong enough press in the lube sizer.
