Be interesting too see how yours turns out.
Ok after cajoling MDT about a mag insert because in CA (Commiefornia) we only can have a ten and MDT is making them in 12. So I received the 6BR internal for an MDT 10 round mag which I had to shorten the spacer which is no problem. To make a long story shorter it doesn't work for the Ruger. The taper of the shell causes nose diving. I played with it for 2 days in my shop. What does work is modifying the Ruger RPR 556 AICS mag to fit the Grendel cartridge. I tried everything even to machining a front spacer with a ramp works great for a single round but when they stack it turns the cartridge nose low. As far as the sled it has worked great from the get go. I made that before I ever shot the rifle at the range. I'm 72 and I target shoot from a bench don't want to fix bayonets and charge anymore.
