Tequila Shooter Posted August 27, 2020 Share Posted August 27, 2020 I've got some "out of round" hulls, the base is fine, just the walls seem to be oblong. I've been scratching my head with the best way to get them round again, suggestions? Link to comment Share on other sites More sharing options...
Hooligan Howes Posted August 27, 2020 Share Posted August 27, 2020 Rcbs makes a die set for brass shells. Link to comment Share on other sites More sharing options...
Abilene, SASS # 27489 Posted August 27, 2020 Share Posted August 27, 2020 I have a steel bar with a hole in it to drive brass shells into/out of to size them. However, I have had a few with oblong mouths that don't seem to want to stay round even after sizing. I think that those hulls may need annealing. These are very old Rem-UMC and Winchester hulls, so no telling how many times they have been fired (some of them 50 times each by me, but with an unknown previous history).

Sedalia Dave Posted August 27, 2020 Share Posted August 27, 2020 For longevity after reshaping them anneal them. If they are badly bent anneal before and after. Link to comment Share on other sites More sharing options...
Colorado Coffinmaker Posted August 27, 2020 Share Posted August 27, 2020 I have run into the same problem. A). The hull mouth is a tad oblong. running it through the RCBS die doesn't true it up. For this, I have a leather cradle for my Machine Vice. I carefully tighten the vice on the hull in about 8 places as turn the hull. Then check it in the RCBS die. Then check it for "Drop In" in my go-to shotguns. B). The hull shows resistance in the RCBS die and after running thru the die, doesn't quite "drop in." Same routine. I also look for the shiny area from the RCBS die and give the hull a little more attention in that area. Then again, "Drop In" test. I have had to do this on very few hulls. I suspect someone has inadvertently stepped on the hull. Annoying that. Link to comment Share on other sites More sharing options...
Blackwater 53393 Posted August 27, 2020 Share Posted August 27, 2020 CH4D has a better sizing die for brass shot shells. Way better than the RCBS, but much more expensive. I got the CH4 dies in a buy from another shooter’s estate. You have to decide if your shells and your frequency of use will justify the expenditure.

Blackwater 53393 Posted August 27, 2020 Share Posted August 27, 2020 I failed to mention in the previous post that I have over 300 12ga brass shells. ALSO!! The CH4D die set came with a roll crimp die! This will help keep the shells round and also improve getting the loaded shells into the gun!! I occasionally shoot brass shells in my ‘97s. They cycle better with the roll crimp and I don’t need as much glue to hold the over-shot cards!! The full length sizing die assures that I can run them in any of my shotguns!!

Lefty Dude, SASS # 51223 Posted August 27, 2020 Share Posted August 27, 2020 All my brass 12 & 16 shells always had a slight roll on the case mouth, helps in many ways. Link to comment Share on other sites More sharing options...
Abilene, SASS # 27489 Posted August 27, 2020 Share Posted August 27, 2020 Lay sizer bar over open jaws of vice. Pound lubed hull into .795 hole with rubber mallet. Turn over, insert nutdriver inside hull to tap it back out. Rarely need the .790 hole. Link to comment Share on other sites More sharing options...

Bought it nearly 20 years ago from Nate Kiowa Jones, but he didn't make it. I guess most any machine ship could pop one out. Edges are chamfered a bit.

Colorado Coffinmaker Posted August 27, 2020 Share Posted August 27, 2020 As seldom as I need to resize or "fix" a brass hull, the CH4D die set is way too expensive. No way. I have only had resistance in the RCBS die on about a dozen cases over at least 4 of 5 seasons and 250 cases in service. It would take about 100 years to amortize the CH4D.

Turkey Flats Jack Posted August 27, 2020 Share Posted August 27, 2020 I anneal them and if the case mouth isn't round I use a chunk of dowel rod to shove down inside. Just taper the end a bit. I want to say the one I've been using is a 3/4" rod Link to comment Share on other sites More sharing options...
Tequila Shooter Posted August 27, 2020 Author Share Posted August 27, 2020 After reading these posts I'm going to try something, here's what I came up with: 1. anneal the brass 2. put brass in a pipe nipple 3. drive a 3/4 inch wooden dowel into the shell TFJ I see we're thinking alike.

Gunner, SASS #1940 Posted September 5, 2020 Share Posted September 5, 2020 Respectfully, I would only anneal the mouth of the case and not the body. Link to comment Share on other sites More sharing options...
Tequila Shooter Posted September 5, 2020 Author Share Posted September 5, 2020 @Gunner I agree that’s all I annealed, just about ½ inch or so. Link to comment Share on other sites More sharing options...

Ozark Shark Posted September 6, 2020 Share Posted September 6, 2020 I have both RCBS and CH4D dies for my 12g brass. There is no comparison. CH4D are not cheap, but will resize and round the brass properly. Link to comment Share on other sites More sharing options...
Tequila Shooter Posted September 6, 2020 Author Share Posted September 6, 2020 I’ve been putting the shells over a ¾ inch steel rod and hammering them. It’s a lot of work but they’re round and passing the sizer check. Link to comment Share on other sites More sharing options...
