Anyone know what powder Black Hills Amunition puts in their 5.56 77 grain open tip match load? This is a notoriously accurate and factory load. Anyone have their own accurate recipe using 77 grain OTM’s? Matt FISH!!

It is a proprietary blend. Probably as secret as the Coke and Kentucky Fried Chicken recipes. ___________________ Just Remember, We ALL Told You So. | |||

The old standbys were Reloader 15 or one other that escapes me at the moment. That’s what the AMU used anyway (15 years ago). Shoot straight, shoot often. Matt | |||

Questions like this are often asked by people seeking to duplicate a factory load. However, ammunition factories virtually never use "canister" grade powders. They buy powders in large lots which the powder manufacturer can't sell at retail since the lot varies from the standards (burning speed, etc.) for that particular retail powder. The ammunition manufacturer then tests the powder (and perhaps blends it with other lots) to determine how much of it to load to achieve their desired ballistics. Therefore, it is generally not possible, simply by knowing the basic powder used in a particular load, to duplicate that load. | |||

It used to be called non canistered powder. Winchester use to use non canistered 4064 for 270 grain Power Point and 300 grain Silvertip 375 ammo. | |||

I went through most of the 15 part series. It looks like AA2520 and PP-Varmint are the best powders for the application, with PP-Varment giving the mildest pressures. Lots of good loads were found with other powders that were 50-100 FPS slower. Matt FISH!!

that's not all ways true.. Hornday uses a lot of Hodgdon powders, like H4350 and Varget. some of your old reloading books will tell you which canister powders was used in factory ammo loads | |||

AA2015 an Accurate powder is similar to Benchmark or IMR3031 | |||

Like I said, the powders used by ammunition companies are usually lots of standard production powders which vary from the specs of canister grade powders. It may be quite true that Hornaday or Remington or whomever uses a version of IMR4064 or H4895, etc., but the version usually exhibits burning characteristics that make it unsuitable to sell as the standard canister powder of that number. | |||

I changed what I typed in the above post. I meant to type AA2520 instead of AA2015. My mistake. Very sorry! Matt FISH!!
