Having read the open-source data and specs on FedPunch and the NAA ballistics data for the 1 1/8 and 1 5/8 barrel lengths, I decided crunching the math to my limited ability and checking things on my favorite ballistics tool (https://www.larrywillis.com/bullet-energy.html). Velocity measurements are okay, but foot-pounds (fp) of energy at impact are more important to me, especially when the target is something other than a piece of paper. My limited science skills came up with the following:
1. FedPunch advertises a 1070 feet-per-second (fps) velocity for a two-inch barrel. That would make it approx (rough conservative estimate) 900 fps for the 1 1/8 and 980 fps for the 1 5/8. Again, these are probably low-side estimates, but not by much.
2. Based on the estimated velocity of 900 fps, the energy output for the NAA 1 1/8 22LR with FedPunch would be 52 foot-pounds (fp). Using NAA's ballistic numbers (mean), CCI mini-mags come out as 40 fp for the 36-grain hollowpoint and 41 fp for 40-grain solid.
3. Based on the estimated velocity of 980 fps, the energy output for the NAA 1 5/8 22LR with FedPunch would be 62 fp. Using NAA's ballistic numbers (mean), CCI mini-mags come out as 43 fp for 36-grain and 44 fp for 40-grain.
4. For general interest, NAA 1 1/8 22WMR with CCI maxi-mag (40-grain solid) comes out as 55 fp and the 1 5/8 22 WMR at 64 fp.
So, this number-crunch seems to show the FedPunch in a NAA 22LR having comparable "punch" as a CCI maxi-mag in a NAA 22WMR.
That then begs the question as to whether the NAA 22LR is structurally capable to normally use FedPunch. The NAA ballistics tables for the 22LR (both barrel lengths) also list the Remington Yellow Jacket (33 grain/834 fps) which has equal foot-pound output (51 fp & 61 fp) as the FedPunch. It was good to see NAA had previously tested a similar round and felt comfortable to list it on its website.
