So, I found these at a local Shooting supply store that has not been open a lot and decided to give them a try. They were just about the right weight for 300 Blackout but I knew that they were not made specifically for the 300 BLK casings.
What I was initially worried about was how short the bullets were and if this would result in the correct ogive and if that might result in missfeeds.
I ended up loading them with 17gr of Lil'gun and with a mixture of cases formed from .223, 5.56 and .222, primed with CCI Small rifle. They were formed with RCBS dies and crimped with a Lee crimping die.
My rifle is a 16 inch carbine set up with a 2x Truglo red dot. I shoot at 50 yards at a standing position (I do not typically bench shoot) and I should also add that this is the first time using the Truglo red dot (I know not the best testing situation for reducing variables but hey, this isn't science class
. Oh and also I should add that I have a Ni-Boron Trigger group and BCG, but I don't believe that would increase the mitigation of misfires or jams.
Anyhow, here are some pics of the rounds formed...
So after all 40 rounds I ended up with no failures to fire, eject or jamming issues at all. The rounds functioned perfectly. The recoil with 17gr of Lil'gun was probably a bit more than it needed to be and I found that followup shots were not optimal and did take time to re-acquire. I will probably try a lower load with the next batch. I think you can see this from my target but keep in mind this is also the first time with a new scope.
So I found these to be some extremely good plinking rounds and I believe once I have a lighter load worked up, they would make excellent rounds for hunting. They are a great choice for those of you like myself who are not able to find Blackout specific bullets to load and just want to have something comparable to shoot. Hope you found this helpful.
