150gr FMJ work well and are fairly cheap. They should be easy to find as well.

I've also got a 10" rifle that this ammo can/will get used in. For the 7" PDW I wouldn't be super concerned about accuracy, cause lets face it, that thing just won't be used at any serious distance anyway. If it will plink a half sized IPSC target out to 100 yds at most then I'd be fine w it. That i...

I've got 2 lbs of Blue Dot and prob 3-4 lbs of Lil Gun and maybe 5 lbs of 4227 so I'm not buying any other powders at this time.

I just loaded 500 rounds of Speer TNT 125 gr using 17gr of Lil Gun.
I've never experienced cold weather problems with this combo.

It had occurred to me to try a slightly reduced load because the 7" rifle does fine with 150gr supersonic loads.

Any good loads for 125gr supersonics. I am using Nosler Ballistic Tips FWIW I did see a lot of people using Lil Gun and I do have a bunch of Lil Gun but the warnings about unstable results in colder temps makes me want to find other options. I was kind of hoping to find a decent load using Blue Dot ...

I just tested 18.0gr of Lil Gun under a 125gr Ballistic Tip and my 7" PDW did not like that load at all. It would partially stovepipe the rounds going into the chamber. My suspicion is the semi-bufferless recoil system of this carbine is the source of the problem. Gonna try the same load in my 10" r...

Something is not right with your seater die. The seating stem should not be deforming the bullet like it is.

The short and simple is work with established safe load data with sufficient recommended safety margin and work up or down slowly. There is too much powder and bullet seating depth combo variations of super vs sub to give out wild guesses. Yes, nobody suggested otherwise. There are loads of publish...

I have 7.5", 10.5" and 12" AR uppers. I like the 10.5" the best. It seems to be the best size length to do everything without being overly long when suppressed.

I don't buy factory ammo. I only reload.

As the bullet seater sets loaded length from base to ogive and my OAL gauge measures base to ogive, it would seem obvious to just use those two values. I've really never considered calculating the datum to ogive value.
