Hello folks... I am going to rechamber a couple Hornet barrels to either .22 PPC or .22 BR. My question for you is which??? Take into consideration primarily availability of brass... As far as I know brass must be made for both, or is there a source that I am not aware of? I already know the ballistic data... PPC is more miserly on powder but the BR has more capacity and holds the velocity edge... Any other thoughts or consideration of which you are aware? Thanks in advance.
.22 PPC or .22 BR???

What action are you going to use?
Both the PPC and BR have bigger bolt face requirements than the Hornet. You'll need to open up the bolt face (and add Sako extractor) if you're starting from a Hornet rifle.
Is this for a target or varmint rig?
For the price and effort of forming brass, I'd go 223 (for similar performance) or if you want something different, ever consider the 223 AI?

I already shoot .223, .223 AI, .22 K-Hornet, .22/250, .220 Swift and .22 CHeetah... I want to try the short, fat BR-Type .22 centerfire (not interested in .223 WSSM)... These are break action single shot rifles, so the bulk of the noted problems do not apply.
What make of break action rifle? I'm thinking that unless you have a suitable case size that you may not be able to simply rechamber on guns such as the H&R series of break action. The barrels have a welded lug at the bottom and rechambering and having to cut the barrel may be problematic. The T/C series guns might be a better bet.
Obviously you cannot rechamber from a larger to smaller chamber... I am using H&R rifles as the platform, the lug has nothing to do with the rechamber as long as the barrel can be chucked, which they can easily... I have done more than 30 rechambers and a dozen rebores on H&R SB2 framed barrels... I have also done a couple of stubs... There is no problem rechambering an SB2 Hornet to either .22 PPC or .22 BR and this is a 1:12 barrel which is good for either. My question did not relate to the rechambering, I have plenty of experience there, it related to which of the two calibers will be less problematic with regard to availability of brass... I can get the dies for either easily... And have upwards of 30K .224" bullets of various weights and designs... Does anyone have input on which of these two is the better way to go???
Is necking down the 6mm BR brass as simple as running it into the .22 BR full length sizer, or is there a need to neck size prior to running it into the .22 BR sizer? If it is a one step proposition then I would probably go with the BR over the PPC... If the brass issue is equal, then I am incline toward the PPC...

I found an article over on 6mmBR.com on the .22 BR and it included info on forming brass... apparently it is a one step process of full length sizing the 6mm BR in the 22 BR full length die... with this info in hand I have decided to chamber these two Hornet barrels to 22BR... it will require swapping the ejector with a .308 extractor, but I have plenty of these in the shop. I am happy with this decision... now to see how they shoot! I'm always excited when there is a new .22 centerfire on the horizon!
