I believe the extra step on M type is larger than the Dillon, so I doubt a lathe is going to help much.

Check the inside of the primer feed housing, it's easy to over tighten the set screws that hold it on, and bulge the housing enough to make slide hang up. Fred

Ran some 45's over the chrono today, all out of my 4" 625. First data is Clays, 4.0 under a 200gr. cast RN, S&B lpp, 1.25" OAL both strings started as 12 shots, but had a few error readings. Nobel Vectan BA-10, 3.8gr, all other data same as Clays

I've been using low odor mineral spirits for years in my 25 yr old Midway tumbler with no problems. Fred

close but not quite, it actually sits under the plastic tip, the cup on the primer bar pushes it back out of the way when it slides back to pick up the primer, the flap is the return spring. Fred

I have some BA10 coming, actually here if FedEx guy would have been on time , I'm going to use it in .45, see how it compares to Clays. Fred

thanks for the info, better get a bearing ordered Fred

just picked a second, older used 550 so I don't have to switch primer sizes, this unit doesn't have the primer track bearing PN # 14015, and I can see where the primer slide has been running on the surface of the press itself, is this how older 550's were made ? or was this one just setup wrong ? Fred

mine came all set up for large.

But Dillon stuff holds value so well and is easy to sell second hand, can always upgrade down the road, with out taking too much of a loss.

02" to .04" ?? sounds pretty excessive, especially if you're loading 9mm, that much variance will really effect pressure, I never get more than .005" variation with my 550B, did you move the decimal point one spot to the right ?

I reload mostly cast bullets, and do my own casting, have been since the 80's, I've never used anything but soap and water, and my lead level has never been over 4. I think D lead stuff is great, for the guy selling it anyway LOL. Fred

I bought a barrel from Shadow Ops last year, it's listed as a 556 socom profile, 16" 1 in 7, I finally got all the pieces together and started assembling it this week, I just noticed the barrel is stamped L .223 1/7 , now I'm wondering do I really have a 5.56 chamber or is it a .223 Rem ?? any help would be greatly appreciated Fred

It's 1.215" - 1.220" , straight out of 550B manual Fred

this is exactly what I do, works well + 2
