No I have not.
As I stated before in the review, per a Magpul rep some 30 caliber bullet profiles may work.
I will try some in the future.
I do hope that they release a 300blk version in the future.
What are the 300 BLK rounds that are rumored to work? Any subsonics?
In terms of loading, would it work with stripper clips and the latch or are you forced to do one round at a time?
It's not so much about whether it's subsonic or not, it's bullet profile. I have tired to pin down what would work, from a Magpul rep, but they are not going to be specific. I would guess that it's because they recommend not using it for 300.
If I had to hazard a guess, and mind you, that's all it is, I would guess that the lighter, smaller profile bullets work, like 147gr.
I have loaded for 208, 220, 147 grain bullets. I will, when the weather improves, try them in the drum and report back.
Thanks for the answer.
When $20 and a mag clamp gets you to 60 it's hard to cost justify a drum but these look good. Nice review.
