loading the .223 to 22lr levels

[gpoldblue]

eagleye....I would let the .22 LR do what the cartridge does the best,but you can improve on the .22 Mag by using a 45gn bullet on top of 6.0gn's of Unique. My Rem 788,.223 shoots 5 shot 100yd groups of .5"-.6". at abt 1900fps. BTW...this load will also cycle a Mini-14,but not with the same accuracy level. Good luck.

Since my last post in 2009 I have loaded a lot of subsonic 223. I use 4.7 grains of TrailBoss with Wolf Small Rifle Magnum primers pushing a 69 SMK loaded backwards. They seem reasonably accurate and hit steel with authority ccompared to a 22lr. Loading them backwards makes identifying them easy. It is also extremely quiet through a 22lr suppressor I got approved and built.

If you will pull up the Hodgdon website and look at .223 loads there is a load for Clays. In a heavy bbl 223 there is no recoil and very little sound. I tried it as an experiment but never got around to accuracy testing.

Here's the Hodgdons data for three diff powders

55 GR. HDY FMJ IMR Trail Boss .224" 2.200" 4.0 1074 (no data given)
55 GR. HDY FMJ Hodgdon Titegroup .224" 2.200" 3.1 1064 4,000 CUP
55 GR. HDY FMJ Hodgdon Clays .224" 2.200" 3.2 1060 3,700 CUP

The 55gr is the only bullet listed. Not sure how a lighter one would do with this load.

Oh yes, for you guys hunting with these loads, I'd make sure game laws allow centerfire rifles on whatever you hunt. Some states limit squirrels to rimfire or shotguns only.
