Interesting! My experience with Lee neck dies and the Redding neck die with bushings was the opposite.

Using my RCBS case gizmo to check alignment, I found the Lee neck collet die gave just as good alignment as the Redding bushing die, and was not sensitive to neck thickness as the Redding neck bushing die was.

I disliked being forced to turn necks, or to get a different bushing for different brands of brass. So, I kept the Lee die, and sold the Redding neck die and all its bushings.

I found this result on my 338/378 weatherby and on my 378. May have something to do with the Weatherby neck. Haven't bothered to try the collet die on my 338 Lapua IM, went straight to Redding and bushings. However I use only Lapua brass which is some of the best on the market. It comes pretty damn straight and uniform on neck thickness.

Hej 378Canuck

Well, you could not get two more different calibres for "our comparison"!

Mine was a .222 Rem, yours the mighty .378 Weatherby.

I too (now) use nothing but Lapua brass in my .222 -- it is amazingly good!

Actually, as a 3 decade handloader, I hate to admit it, but I hate a devil of time even matching the accuracy of the Lapua FMJ factory rounds that I purchased to get the brass to reload.

My best tailored reloads with Norma brass just neck sized were still less accurate than those Lapua factory loads.

I have a .375 H & H so I am not a stranger to recoil, but I have fired a .378 Weatherby -- I salute you and your rawhide-covered cast iron shoulder! smile

Actually it's not so bad after I stuck that 30+ oz NF scope on it and the heavy McMac-tupperware stock. If I run out of bullets, I could still club them to death with this thing. LOL

I was very skeptical, but gave them a try when the last round in my 5 shot magazine in my .375 H & H would get pushed in the case by recoil because I was seating the bullets out where there was no ring to crimp on (with a conventional die anyway).

Three rounds in the mag were no problem, but this rifle held 1 + 5 shots and the bullet in the last round would start to move in spite of an undersized expander ball in my sizing die.

The Lee collet crimper die allowed me to crimp even on a smooth X bullet, fixed the problem of the bullet moving, and cost very little. I do not recall accuracy changing at all, but some have sure reported improvements.

I understand Lee crimp dies for pistol calibres do not use the fingers and collet, but I sure like the rifle dies (which do use this approach).

Things come to mind... I've never seen a long range shooter or BR shooter even THINK of using a Lee die.... and I"ve never seen either see the need for a crimp as a good thing.

I"ve run well over 100K rounds through ARs, maybe double or triple that even.... and never crimped one round.

IMHO there are better ways to skin a cat, but IF it works for you, then thats all you need to know.

I do have a handful of Lee dies collected over the years and I have done my best to not ever buy another.

I've never seen bullets slide back in the brass from recoil. You need to anneal your necks more often to remove the springyness(may not be a word). Like I said before after 5-6 firings they seem to spring open a bit after sizing. My findings. I don't know metalurgy but something seems to happen to the brass and it develops a memory. Maybe others with more experience know why or can explain it better than I can.

I am sold on the Lee "Factory" Crimp die especially on hard recoiling pistols and rifles..Never had a bullet even come close to moving on the hard recoiling 454 Casull and it helps big time with heavy bullets in the 45-70..I would hate to think of reloading either without it.

I have both RCBS and Lee dies and use the Lee's more often.

I have used the crimp dies in several rifles that i couldn't get to shoot otherwise and got an improvement in them all. They were all auto's or levers or magazine rifles that had short magazines compared to how the barrel overall length was set.[mainly browning levers and autos] One 270 blr of a friends went from 4 inch groups at 100 to 1&1/2 just from crimping. I now crimp any rifle i can't get to shoot a reasonable group.
