These are specifically designed for elr. Lots of people starting to shoot 22lr at extended ranges, so there is a market.
For 22lr, and small rimfire in general, the powder charge and priming is the driver of accuracy. It has to be consistent. Also, supers suck for accuracy at range. As soon as the round drops down through the sound barrier, turbulence is created and the small 22 rounds with low bc's tend to get wonky and accuracy suffers greatly. This pretty well knocks out 22mag for elr. The rounds are super. You could ramp up the bullet weight, but would need a much faster rifling to stabilize the heavy projectile.
The 22lr and the market is ready for elr. Can make a 40-45 grain projectile to work with standard 1/16 twist barrels. Keep the velocity around 1000 - 1050. But, G1 bc's with traditional 22 projectiles is around .145. The thought, I'm sure, is that the projectile is where they can get some some headway. Make something with a higher BC that is designed to work in existing rifle platforms.
The other real struggle of rimfire is consistency on the priming and powder charge. Cutting Edge is a bullet manufacturer, not an ammo mfg. Im assuming that they will be collaborating with another ammo mfg to put these out. I know they have worked with Sierra in the past, but not thinking that CCI will be the route to go as they have not been good at making consistent ammo. Federal doesn't even make their own match 22lr. Probably realistically looking at RWS (doubt that works with the Prime ammo debacle), Eley or Lapua to make these things and they are all overseas. They will need to be single digit sd's to hit at range.
I wouldn't be surprised whatsoever to see these around 50 to 60 cents per round. Id glasly pay that. Hell, im paying about 40 CPR for my match 22lr ammo now, and realistically, shoot it to 400, although I have had success at 500 with no wind.
I'm excited for these. I revamped the optics for my T1x with a new rail and scope and can dial for 500 now. These would be perfect.
