.41 Mag Coated Bullet Question

[Rule3]

All my LEE seating dies have ONE seater "plug" they seem to work just fine on any profile bullet be it lead, coated or FMJ?
RN, FN, HP SWC. WC, heavens even works for a SW M52 HBWC soft bullets. Even with a FCD which is a roll crimp

But I guess they make more than one profile (seater plug) for a reason.

Here are the bullet seating plugs I made to fit my Hornady seating dies and MBC LSWC bullets. These are a tight fit with only a few 1/1000's clearance at the shoulder/swc riser. This is to ensure it goes in straight, self aligns.

Very nice! I did something similar for a Hornady seater die body for .32. I made the part that holds the seater stem(s) and made two stems, one flat and one very much like yours. I put a micro-adjust top on the die body and use it to seat bullets in both .32 Long and .32 Mag. I use the flat one for wadcutters/semi-wadcutters and the other one for RN JHP etc. Looks like I could use it for semi-wadcutters as well.

Well, Lee will make custom seater plugs. I suppose they could make a flat one, and I wouldn't even have to send them a bullet to work from. Or I could mill mine down at work. I assume a flat plug would work okay with an XTP, as it does have a flat rim around the HP.

I suppose if you wanted it flat you could just fill it with JB weld.
Of course milling would be nicer!
Like Rule3 I have used my stock lee seater with all shapes of .357 bullets and it seemed to work just fine.

I haven't had any problem with my Lee .44 or .357 seating dies either....at least that I can recall.

But now I think about how much brand new brass I've loaded with coated lead bullets. It's not that much, and most of it was quite a while ago. Most of my brass is well used and on the edge of replacement. I may have had this situation happen before, but because I was new to reloading when I broke in that brass, I just considered it teething problems.

I might need to test this with new brass and my .44 load, which I have been reloading free of problems.

I have loaded a boatload of XTP and Gold Dots with the plain old factory "seater' plug" As well as soft lead SWC bullets

I guess if you feel the need to spend some money.

99% of reloader's typically use flat or round nose bullets when loading for most cartridges. The long slender points on the Hornady FTX (and similar) bullets certainly helps the ballistic performance of the round, but it does increase the overall length of the cartridge when the bullet is seated so that it is at or close to the rifling. The overall length listed is a dimension that will provide action clearance in the shortest standard magazine or feed mechanism. You do not have to observe this maximum overall dimension, and most reloader's do not, as best accuracy is obtained when the bullet is seated as close as possible to the rifling.

If it is essential that you must seat your bullet to the max overall length, or if your rifle does not allow the cartridge to feed with the longer overall length, we offer this custom bullet seating plug service.

Some 460 SW with FTX bullets charged and ready to seat with a basic old Lee seating die. Gads can it be done??

My 41 Mag die set is RCBS, and I have one concave seater plug stamped "RN" and one flat one stamped "SWC".
