So this is exactly what the title says. I am building a wildcat 6.8 round to hold a .224 Diam bullet for varmint that is flatter shooting. Feel free to follow this feed for updates.
So far I have gotten ahold of the reamer schematics for a custom barrel and sizing die. Case capacity should be around 36 grains of water at the rim. I am thinking of a slower burning powder used is similar rounds like Hodgodons H380 with a 40 -55 gr round.
Approx. velos out of a 22” barrel is 4000 with the 40 gr Nosler BT and 3750 with the 55 gr
This brings the question, why this round when proven rounds exits? Thanks for asking.
22-250- Not offered in AR-15. It’s as simple as that. I love the 22-250 AI as I can push a 80 gr bullet 3800 fps but it doesn’t offer as fast of a follow up shot when callin in doubles or triples on coyote
.223/5.56-this is tried and true round but in some cases I want to have more terminal balistics past 400 yards which is where this round gets iffy.
22 nosler- Brass. That’s just about it. I have heard some reports the brass has been fixed but I was leery about it and to have a custom barrel made with an extended gas system would add 2 lbs to my build
22 Creedmore- Same issue as the 22-250. It’s in an AR-10 platform which would add too much weight when tracking into calling spots and deer blinds.
The 22 PDK, as far as I can tell, hasn’t been made or used in about 9-14 years (only forums I found) it seems like a nasty varmit round that can approach 22-250 numbers in an AR platform. I am having trouble finding barrel blanks haven’t decided which one I wanted to go with. I will be going with a Wilson Combat BCG and Geissele SSAE trigger. I will upload the Reamer Schematic with this forum as well
