Raydee38 Posted November 14, 2015 Share Posted November 14, 2015 I am loading 223 on my Xl650 and am having a issue with brass shaving off my bullets when loading. I am using the Dillon RT-1200 trimmer which everyone knows sizes the case mouth a little tight to seat your bullets after. What I have been doing is manually deburring and chamferring the cases which is pretty time consuming. I see that some of the jacket on my bullets are being shaved when loading BUT they are tight enough where I don't have to crimp any of my rounds which I do like. If I decided to use a Lyman M die to stop the shaving of the jackets will I have to crimp each round after? It's probably debatable but is shaving a little of the bullets jacket really a big deal?

caspian guy Posted November 14, 2015 Share Posted November 14, 2015 I use an m die specifically to avoid that issue (and to avoid having to chamfer.) I have the m die adjusted to just barely open the case miuth. I do have a dillon crimp die in the tool head and I have it adjusted to just remove the bell the m die imparts. That has worked well for me. Link to comment Share on other sites More sharing options...
Beastly Posted November 14, 2015 Share Posted November 14, 2015 M-Die for the win with flat base bulllets. Also recommend this: http://ballistictools.com/store/case-mouth-gage-224-308 Little-no crimp required to 'fix' minimal M-die expansion. You already get tons of neck tension with the Dillon size/trim gauge. Link to comment Share on other sites More sharing options...

Spanners Posted November 14, 2015 Share Posted November 14, 2015 (edited) See below pic stolen from Mr Bullet Feeders Page The backup rod has expander section in it. (middle part with arrow) Just install it in a station after your trimmer I havnt trimmed up any of my rods Edited November 14, 2015 by Spanners Link to comment Share on other sites More sharing options...
Raydee38 Posted November 14, 2015 Author Share Posted November 14, 2015 OK that must be from the Super 1050 reloader? Link to comment Share on other sites More sharing options...
Spanners Posted November 14, 2015 Share Posted November 14, 2015 Sorry.. have reread. I skimmed the 1st post and saw 1200 there.. computed that into 1050.. as I'm ordering parts for my 1050s etc and have it on my mind. You dont have a 1050, thus you dont already have one...... Either way, that or a M die will work Try a normal resizing die in the last station if you can get it to fit and back it off a turn or so and see what the burr is like.. should wipe it out Link to comment Share on other sites More sharing options...

Raydee38 Posted December 9, 2015 Author Share Posted December 9, 2015 Well I got my M die in the mail today. I got it all setup and ran some flat base bullets through the press. The necks are still tight but I am not noticing and shavings from the bullets so I am guessing it is working right. The instructions on the die say that you can screw it down some more and kind of bell 1/16" of the top of the case for cast bullets but I am guessing I won't need to do that. Since I don't normally crimp flat base bullets I tried forcing the bullet in the case to see if the neck tension was enough and the bullet did not budge so I think it is good to go. I will have to load some boat tails next and see how they work, I will probably put a light crimp on those like normal just to be safe.

JatCarver Posted February 6, 2016 Share Posted February 6, 2016 Instead of starting a new thread I will ask here, anyone else have there M die stick while its pulling out of the case mouth jarring the press a little. I tried polishing it and it didn't make any difference. Link to comment Share on other sites More sharing options...

I tried polishing it and it didn't make any difference. I run 223/300 BO brass in quantity on 1050's and when the case is in position 7 (empty) I will run a lubed brush down the neck. Doesn't take any extra time and the benefit is the brush removes chips and applies lube to make the expanding operation easier. Link to comment Share on other sites More sharing options...
roxfo Posted February 12, 2016 Share Posted February 12, 2016 anyone else have there M die stick while its pulling out of the case mouth jarring the press a little. I tried polishing it and it didn't make any difference. I used to get a bit of sticking when I expanded with M dies. These days I use a Sinclair expander with floating carbide mandrel, which reduces the sticking, then flare a little with an M die with a custom mandrel; the first part is fractionally undersize and just serves as a pilot, so it is flaring only and doesn't stick.
