7/6/2023 0 Comments 223 subsonic load data![]() Then my Brother in Law who is a FFL/SOT bought one to demo for a local dept.So whenever there is an MG shoot.the family enjoys shooting P90, G36, MP5, MP5, UMP's. My first P90 experience was from CMMG inc letting me send 50 rnds down range in one full burst.Loved the way it handled without having worry about the recoil. NOW I can move on to the 62 Gr M855's that I want to crank up. I recocked the bolt manually and they fired fine. I don't know if this is because the bolt didn't cycle all the way back or a mag failure. A little louder but the sound came from the chamber area.still silent out of the suppressor. ![]() Primer Remington small pistol magnum 5 1/2Īlso tested same load with a Wolf small rifle magnum primer. Whoo hoo!! I found the round for the subsonic sound!Ģ.7 Gr Hodgdon Clays (not International Clays, just plain ol' Clays) I will load some more up and take them out to chronograph them in the next couple of days Next round loaded with authority and fired the same. The only sound was the action moving and there was no flash (did the test at night). I didn't want to drive an hour to test function of this load before I checked to make sure it even worked so I loaded 2 rounds with 2.4 grains and fired them for function only into a pile of sand 5 feet away from the muzzle. A curse because racking the bolt again takes you off target and is more noise than you want to make. A blessing because there is no sound but the drop of the hammer. 223 rounds are so quiet you can hear the click of the hammer and the thud of the bullet hitting the target and nothing else. 223 data shows 1035fps with 3.3 Gr of powder under a 55Gr FMJ. 223 can handle 52000 cpu but it is a super clean burning powder and it will certainly all burn before the bullet gets even 4" out of the case. Sounds crazy and Hodgdon won't give me a yea or nay on it but Clays is the powder they used for the. ![]()
