Well I am having so much success with 303 Enfield I though why not 223. Just to make thing interesting Hodgen has data for a 55g bullet and they have it at 4g powder but that is all they have and it is listed as max for that combo. 4g is not very close to 1/2 full so if you use the other formula you could go to 7 or 8g I would think. Well I guess you need to remember you are talking 55g bullet vs 150g or 125g. But still I would think 4g max is a little light but I will shoot it and find out. BTW 223 because I have a bolt rifle in that. Craig
Looks like they mean it as a low recoil subsonic load. Listed velocity is 1074 fps.
Makes sense. If you push into transonic or just above, accuracy will be terrible with that little 55 grain bullet.
If you have a levergun, wait until you get to play with reduced loads in the lever guns. What a hoot that is!
Just as a FWIW, you need to keep separate the brass on that 223. You're going to have somewhere around a 25lb hammer hitting the primer and it will slowly push the shoulder forward. It will be just like excessive headspace and should you load that brass with full house loads, yer flirting with a BOOM! Shooting the reduced loads thru the Springfields for the Boy Scouts, the brass will go thru the gun 3 times and then it's no longer safe brass to shoot. A rimmed cartridge like the 303 does not have the issue, rimless only.
Of course I don't even need these to be that low as there is no real recoil to deal with so I may just shoot and see what it does. Thanks for the input guys! With any luck this will be the end of screwing around with Trail Boss. Ha Ha!! Craig
Not only the headspace issue, but given the cost of a 55 grain head that makes some pretty expensive ammo that is about the same power as a 22LR.
Shot the 223 with 4.0g Trail Boss today and it was less than light. Grouped very well but was light. I liked it though. Not an everyday shooter but nice for once in a while so I will load like 50 of these. Craig
