What is the common method to reduce the neck diameter for 22BR brass?
I have a 22BR bushing die. Just run 6BR brass through the 22 bushing?
Do you turn the necks before or after running brass through the bushing?
Thanks

I would not use a bushing die for case forming. Get a full length sizing die.

On my 22BR, I went with the .243" neck chamber, mainly because I'm a masochist. The reduction in diameter is so great, I ended up turning it once as 6mm and then a finish turn as 22BR after first trimming a big chunk off the end to fit the 22BR chamber length. Some on this forum have gone with looser necks, some even no turn chambers. I believe some have even gone with no turn, no trim chambers and reported very good accuracy. There are so many flavors of 22BR out there, what you end up having to do will depend mainly on which chamber you have. However, form the cases with a regular 22BR FL sizing die.

I guess it pays to be ignorant. I use a Type "S" die with a .242 bushing to make all my 22 Dasher brass and haven't lost a case yet. Might make a difference with the longer 22BR neck. Suggest you give it a try before you buy a form die. Invest a piece of brass, you might win.

I have always used a 22BR full length sizing die (Redding) then I trim to length
1.515, next I neck turn so the neck is .0115 thick, after that I use a .244 bushing die. The loaded round is .246 and the chamber is .248 . The 22BR full length die might be pricey but well worth it! I have never had a problem.
It shoots well in the low .2's

I have a 22BR with a tight neck dim of .243. Definately would like your information for your process of turning 6BR brass into 22BR tight neck brass. Not sure of what dies I may need, or the steps required to get finished brass, but sure would appreciate any help.

Well now, you DID say "any help"..........You might regret that but here goes.....

99.9% of the 22BR cases on God's earth are formed by simply stuffing a 6mm case into a 22 die. A small percentage of these are adjusted for "crush fit" which makes better brass...but ALL cases made this way are crooked, ie the necks vary from the rare centered one to as much as 15thou of runout with most showing about .010 on the dial and the result is that they sit in the Chamber cocked out of line......so they fIreform in a banana shape.

If for some reason you want straight cases the answer is to either make yourself a stepped-neck die, or order one from Neil Jones.

It seems a hassle but in the end it pays off in case life, with a Jones die you can fire a case 50 times.

Plus, no matter what the guy on the innertube tells you, only with fitted dies can your gun shoot to it's potential

i still do not understand why some/most people cut so much good brass
off the necks of their brass.
i trim at 1.545 for dasher and 30 br.
but then i fire form up or out, not down.
