I've done that with my RFBR rifles, but never with a CF, yet anyways.
20-222 or 20 practical

I've got 20-222, and I only size half the neck (Bushing Die) for seating the bullet. I'd like to think that the fire-formed section of the neck provides perfect centering of my cartridge. 
of course I think a lot of crazy stuff
I don't think you would want to do that with those crude, short necked military cases. jd

Hey Jepp, what weight bullets are you using in your 20? My little 32's kind of hit the wall about 300 yards out. jd
How involved is the case conversion process???
Since I already have a 20 practical and as i like all your suggestions i'm leaning towards the 20-222 and the 20 bobcat. unless something better comes along.

That's often true, but Imma tell ya that I went with the 20-222 because I like things on the mild side for my varmint shooting. Heck, that's why I had a 222 instead of a 22-250. I'd have probably thought more about a Vartarg, except I've got a 218 Bee that kind of fills that slot.
There is plenty of room to go hotter with the prac, or the tac, Ruger, or the crazy hot ones. but I'm wondering just how much more efficient they are at that "beyond 300" thing. Our little 32 grain bullets have such a wimpy BC that real long range is pretty hard on performance. I've never chronied my loads but I'm assuming they're leaving the rifle at around 3500 fps. And I'm gonna tell you that at 300 yards they're starting to drop like a rock. I do a lot of missing out at that range. From zero to two hundred, I hardly miss a squirrel. jd
20 TAC

Folks recommending something they don’t have would seem to offer questionable input if they have no experience with it…or am I missing something? On the other hand, folks giving first hand information on chamberings they do have has probably caused more than myself to end up owning it too. I have no regrets having fallen prey to this. I think they call that ‘purchase mentoring’. I’m a willing victim and have been known to be on the persuading side too .

Size the necks down to 20 cal, load and shoot. I have a 20 Bobcat die set and I use that die, but just like 20P, you can use a 222 bushing die to do the same.

Well I've got a few regrets about the time I got suckered by a guys wonderful description about the rare and innovative .491 Burgness Stratness.
jdOk fine. In the meantime count the number of “I”
My point is that every time someone asks a technical question it seems to turn into an open invitation for people to talk about their own stuff. Think this statement is an exaggeration? Read through similar posts.
Is the Bobcat a 30degree shoulder or a 40? My way of thinking is i like the idea of straightening the body with a 30 degree shoulder and retaining the same neck as the 222

20 TAC

I think your point is valid and fair. Maybe it would be fair to say we both see the same trends but just in different lenses. In my case, I don’t have a 20 Practical to compare to the 20-222. But I do have a 20 Tactical as well as 4 other 20 caliber chamberings. None of them except the Vartarg were mentioned in my posts and per the OP question being 20-222 or 20 Practical, most would agree the 20 Practical and 20 Tactical are ballistic twins. So I felt confidence in my opinion on the “either-or” question posted with my preference to the 20-222. I will admit fault for giving the Vartarg undeserved attention in this case as it wasn’t part of the OP’s choices. I could have kept it out of my post.

The bobcat came from Kevin Weaver I believe. Years ago I almost reached to him and just never did, neat lil round.
IMO if you have either a 223 or 222, then go with the 20 caliber version of whichever you have. It’s hard not to favor the 223 or 20 Practical because of the wide availability of brass, and reloading components. I’m a 222 guy so went with that because I have components and dies, etc. For the most part, you’ll be shooting 32, 39/40gr bullets, so either has the capacity to push those plenty fast. Another rationale, modern 20 Practical, nostalgic 20-222.
one will be 20-222 and the other is going to be a version of the bobcat but with a 30degree shoulder. All good info in this post.
