I just had my 20 vartarg barrel made by and headspaced by pacnor. I sent a dummy round that I made prior to sending. They set the headspace exactly at my dummy round which made for a tight chamber with my dies. IMO, I think this a feasible to do by yourself by setting your die longer than you plan. After your barrel is screwed on see how far out you have to use your die to get your bolt to not close. If it is more than .005, you may want to take some off the barrel or you just use a little longer headspace for your rifle which will probably give you a bit more velocity.
I haven't hunted it yet, still doing load development. I have only tried Sierra 32gr Blitzkings so far. I started with LT-30 and haven't found anything amazing with that powder, didn't shoot anything better than about .4" groups at 100, but no worse than .8" groups either. Found a lb of H4198 and just shot some groups today. Getting consistent .35" groups with 18.2 and 18.4 gr. Need to do a comprehensive seating test at 18.3gr. To get near the lands, I have only about .125 of the bullet in the case, so freebore is regrettably on the long end of what I wanted. With only 1lb of H4198 will need to switch to another one after 400 rounds and hoping I can get Lt-30 to shoot.Have you had much opportunity to get out & shoot your CZ 20 vartarg yet? Curious what your experience has been like? For example how has she fed from the mag, were any mods needed, what bullets have you tried?
I for one am always interested in how people do things. Please, post your process. Thanks.I haven't hunted it yet, still doing load development. I have only tried Sierra 32gr Blitzkings so far.

I converted a 223 rem for this build. I purchased a bobsled single shot adapter for it, but it doesn't work. It is too low and it doesn't get the bullet into the chamber at a good angle. Gets hung up when closing the bolt. I have a flush mag and feeding them one at a time just sitting it on top of the mag works great. I haven't tried feeding from the mag yet. The trigger is so good and the recoil so low, can hardly tell it was shot until I see the hole in the paper. I see why people love this round. Will get her out on pdogs in the next couple weeks if I can finalize a load.
Making brass out of Starline 222 brass. Actually got a nice little system down and I can make 20pcs in about 30-35 minutes. Have a procedure written down, will post it up if anyone is interested in it. The harbor freight saw makes is so easy. After 3 firings, I can tell that my brass needs to be annealed already.
Sounds like you are off to a good start. In the absence of 4198 offerings it seems N120 & perhaps N130 may be worth a look as well.I haven't hunted it yet, still doing load development.

I headspaced mine off of some brass that I purchased from @TheCZKid . Then, I got worried about it, as I am wont to do, so ordered a headspace gauge. I could have saved the money: they were literally the same. Closed on the go, didn't close with one layer of tape on the end. Perfect. But at least I feel better. Well, except for the wallet....Think I'll give it a go without a headspace gauge.
