Specific load data has also been developed for 5.56mm NATO, when shooters are. I also want to play with different bullets in the 69+ gr range.Ī heavier projectile version of the 22lr out of and AR that doesn't require a conversion kit, different magazine and the issues associated with 22lr fouling AR and can. this statement, we have successfully run subsonic. The load data provided by Accurate Powders suggests a 16 barrel with 1:10 twist rate, Remington cases trimmed to 1.358, and Winchester Small Rifle primers. I'd like to get it down to and average of 1050 fps (true subsonic level) with a SD of 10 so I am going to play with the powder and start working down in 2/10 increments. The fast burn rate makes it ideal for use in subsonic loads, producing enough pressure to cycle the action even when pushing the heaviest bullets out of the muzzle. I have no idea on what it's max effective range would be but I'd say 200 yards would be a safe bet. Here you will find load data for some of. We are currently populating the cartridge drop-down menu with updated cartridge renderings, new propellants and bullets, and links to complementary product pages.
LOAD DATA FOR SUBSONIC 223 CRACK
Primer crack is less because of bolt staying closed. Get the most performance from Federal components by using our carefully developed, high-performance reloading data. About as loud as subsonic 22LR out of the AR w/can. I load a 57 gr Hard cast, gas check bullet at 2500 and it will cycle reliably. To load subsonic (under 1100 fps) you will be hard pressed to get enough gas to cycle the action. Even then, with low velocity, you may still get key holes 100. Looking to see how it works in 223 Rem Primary rifle is a Rem LTR with 20 9 twist.
LOAD DATA FOR SUBSONIC 223 MANUAL
These will not cycle the bolt (so single shot and manual rack) You will need a fast twist barrel (1/7) to have any hopes of stabilization. All the load data I have found is either way too fast (3000 fps+). 1x7 bbl with an AAC M4-2000 that will run just under 1,100 fps in warm weather Would actually prefer it didnt cycle the action to keep noise down, but most of all must stabilize so theres no chance of baffle strikes. I shot these out of a AR15 w/ 1-7 twist 10.5" barrel / AAC can (these would be excellent on a suppressed bolt action. 223 load data for suppressed use Can anyone recommend a load for use in an 11.5-in. 223 subsonic.ĥ.2gr Trail Boss (fills case nicely - does not meter to well though *donut shaped powder)
Here is a load i cooked up (after a lot of internet research on the subject) this weekend for.
