Scratching my head.

[[email protected]]

So I purchased some once fired .223 lapua brass from a fellow hide member. I resized it all with my redding type s die.

When I went to seat a 80gr berger in the case, there was no resistance and the projectile was not held in the neck.

I measured the outside diameter and compared it to some new brass and the necks measured the same on the outside. What's going on?

S-type dies need a bushing in order to size the neck. The bushing is not part of the die kit, and in order to compute which bushing you need, some measurements of the bullet and case neck wall thickness are in order.

i'm resizing with 247 bushing currently. i have both a 224 and 225 in route. i was just scratching my head because it would make since that if the new and once fired measure the same outside diameter, then i should be good to go.

Id bet a 241 bushing is going to work best, a 247 bushing is the same size or even bigger as the loaded shell, how the hell is that going to work.

i measured a loaded case at 250 so i figured 247 would have been the way to go.

Better cancel the 224 and 225 unless you have a .17 cal gun, .243, 244 is what I use.

Now Ill have to load up one of the lapua brass I have and see what it measures at, win brass measures .245. I dont think lapua brass is .005" thicker.

Use the .247" as a step down bushing if your barrel blows your throats out a lot, say to .250"-.255".

I've got .242", 243", 244", 245", 249" and a .250". The latter two being step down busings. .244" and .245" should suffice in most situations.
