Re: Anybody handload for their DPMS SASS ......?
44.3 of RE15 and a 175 work well in an AR10. The AR type gas guns are not like M1A's or Garands, they can take it.( well the M1/M1A recievers are very strong, but the op rods don't like the high port pressures so much. ) Alot of people say you can't load semi auto's like a bolt gun, but most of that is primal knowledge passed on from M1A or M1 shooters, and yeah, they have to be careful. An Ar10 or DPMS/KAC can be worked up for just like a bolt gun. Go slow and look for the warning signs, and you will be ok. You can add weight to the carrier or buffer or even use an adjustable gas block to slow the carrier speed down some, but your not going to bend a $275 op rod. Excessive carrier speed and accelerated wear are the only downside, but it can be adjusted for. No biggie. As an example the AMU shoots 185 bergers over 45.0 of Varget in AR10's with no ill effects. That is a smokin load for a 185. I have run 155's over 46.0 of H4895 with no issue, and 190's over 43.5 of RE15 with no issues either, but now I shoot them over 42.5 of LR surplus powder and its more accurate, and I will be working that load up some more as I was seeing the beginnings of another node around 44.0 or so before I deployed, and could get 190's to over 2600 fps accurately with it. But I know 42.5 works and I have not been shooting in a year, so thats what I loaded up for next weekend. Historically for me, the AR10 has started to show pressure signs right at where my M700 5R does, and the two both will shoot the same loads well, with the edge going to the 175's for the bolt gun, the 190's in the AR10.
Just follow the signs and work it up in your rifle just like any other load. If your loading for a Garand or M1A, definately stick to known loads and limits used for them, parts are pricey and scarce at times.
