Varget is a little long burning for an autoloading rifle with a shorter barrel so incomplete powder burn is very likely, not to mention extremely high gas port pressures on anything shorter than a rifle length gas system. This includes H4895, H4198, H4350, and Varget, as all are long grain. I still trickle all my long grain powders by hand, or with my CM. With 8208 or any ball powder, I can hit those numbers with my Hornady drop which has been polished to a mirror shine internally. 05gr difference max being semi acceptable. On a 10 or 20 drop check, I want no more than a. I wouldnt consider any powder that will not reliably run thru a powder measure with 0 issues to be a good powder for someone starting out. I never said Varget was a bad powder, but for 223 its actually a pretty poor choice in my opinion and I was simply providing a viewpoint that says 8208 is a great option for someone that is just starting out as its easy to use, and very very accurate. There is no reason not to use the powder you want to use because of people spreading a misconception thatextruded powder will not flow well in a can be done and done well. I just finished 2k rounds today with varget in 308, getting throws +- 0.1 grain.Īll you have to do is polish the powder funnel and the slide in a Dillon powder measure, or use a RCBS powder measure with case activated linkage. I have loaded thousands of rounds with Varget in 223 and 308 for 3gun on my 1050, and know lots of people who also do it on progressives for bulk loading. Maybe one of these days I will actually get around to doing a proper OCW or ladder test. I have also used the Nosler 69 grainers which again, are cheaper than the SMKs. They were running about half price of what the 69/77gr SMKs are running. I did buy 75 grain Hornady's from Hi-Tech ammo. It has been cleaned, deprimed, trimmed, and swaged, so I just drop it into the hopper of my 650's casefeeder. I got the brass from Fast and Friendly brass sales. I haven't had a chance to chrono these rounds either.Īll of it was Lake City once fired brass. That was.get this.22.5 grains of H335.Īgain, I just cranked out 200 or 300 rounds like that.
#Subsonic 223 with 69 bthp manuals#
Then I pulled another charge weight out of the reloading manuals for the 77SMK's. I made easily 200 rounds with that combination. So for the 69gr SMK's, I used 22 grains of H335. I basically just picked a charge weight out of the reloading manuals. All you can hear is the bullet smacking the steel swinger.I have not experimented that much with powders or charge weights. I cheched this myself with a MP3 recorder and mic and in person by standing a safe distance behind a barricade ( huge white oak ) from the 6" swinger. When fired even single shot through an AR w/ suppressor these rounds do not make any noise that can be heard at that distance. 22LR.įor SHTF situations this load can easily kill a person or deer size game at 175yds with a head shot. Loads using the PRVI 75gr BTHP-M bullet are pretty impressive compared to a. 223's w/ Hornady 60gr HP 1,050ft/sec ( just for kicks ) that shoot flatter, are more accurate and have more energy at 175yds ( I have a target stand w/ 6" swinger at 175yds ) than the SSS. The Aguila 60gr SSS only has a muzzle velocity of about 950ft/sec with a round nose bullet and I have loaded a few. 22LR round that has the downrange terminal ballistics of a subsonic 60gr or heavier bullet. Actually if I was going to build a suppressed big bore AR I would go with something based on the 6.8 brass and. 300BU/Whisper/etc would be nice but the OP asked about subsonic. If I wanted a suppressed AR I would go with the 300 Black Out.
