    There are a bunch of home grown loads out there but you could be taking a risk and a 40gr 22lr bullet going 1150fps isn't going to do much less than a 55gr .223 bullet going 1150fps. Now if you step up to a 77gr you'll get a bit more penetration. I have heard 4gr of Trailboss works with 55s and 62s but use at your own risk.
