With noise comparable to a large air gun, the ASP gives the operator total stealth to achieve their objectives. 223 subsonic round that will fully function a military M4 and/or commercial developed AR-15s. To achieve subsonic velocity one must change the powder, powder charge and seating depth. Designing subsonic ammunition is a delicate art, there is no one size fits all as with other ammunition. This resulted in the Extreme Shock technicians and ballisticians developing in 2 separate subsonic loads. The military M4 chamber is larger than the commercial ARs. However, there is a quite a difference in the military M4 as opposed to commercially marketed AR-15 series of rifles. These guys have made an industry out of wiping out the general supply of ammo.However, due to it’s popularity, shooters was using the round in various weapon platforms. Same story we have all heard over and over. Others, as we know, take there whole family and/or friends to each buy a limit so he can sell them. He points out how one guy brags in forums online that he buys his max and then goes to his truck puts on a jacket, a hat and sunglasses and goes back in and buys another limit. His theory aligns with mine in that many of these guys are unemployed and have the time to dedicate to finding ammo and they are making a living reselling. He also goes into the reasons for the shortage being resellers that buy up all the ammo and resell it for up to $100 a brick for bulk ammo just like we have all seen. Not quite as good as many of our top loads with 22 LR but plenty good for plinking or hunting. If you want subsonic he loaded the 42 gr Calhoun HP Bullet over 4.0 grains of Blue Dot and got 1,113 fps and the groups averaged. The most accurate load listed is the Speer 40 grain Spire SP with 16.0 grains of IMR 4895 with Rem 7 1/2 Small Rifle BR Primers at 1,586 FPS His accuracy 50 yards range from a HIGH of 1.01" to a very decent.

This month's issue of Handloader has two articles about reduced loads. 300BLK was created, no?Įdit to add: Hodgdon now links to their reduced power data right on their home page. Of course, difficulty getting acceptable performance out of subsonic. Having said that, I did not find such reduced loads to be very accurate. Average velocity was 1153fps from a 16" barrel. The PDF explains how to do this.Īccording to my reloading log, I used 69gr bullets to achieve it in a rifle with a 1:8 twist and last loaded it in 1997. However, since few manuals include Trail Boss in their recipes, you have to measure its maximum volume in your case and use the 70% rule against that measurement. You can perform a similar search to find the same for Trail Boss. They essentially use the 60% of their published maximum rule for that powder. Google "H4895 reduced rifle load" to find a PDF from Hodgdon explaining how to do it. I do not publish specific recipes on the intertubez, but it can be done with 4895 and Trail Boss, and I have done it with the former.
