Not so great...

I was excited to receive the 3 ASC 6.5 MM Grendel Magazines I ordered, and put them into use. Today, I went to the range at Quantico and shot with some of my friends, and after 7 shots the first Mag misloaded the Hornady plastic tipped hollowpoints, bending the tip. I removed the misloaded cartridge, and cleared the Grendel, then reloaded the Mag, and on each shot afterwards, the problem repeated-over and over. After 4 or 5 shells had the plastic tips ruined, I finished up the 25 rounds manually, then moved to the second Mag. Exact same issue. After 7 rounds it began misloading the cartridges. It gave me grief, and it was 2 of the 3 mags. I didnt bring the 3rd magazine as I had only planned to shoot 50 rounds today. Maybe bad spring pressure...I honestly cannot say. Manually loading the Grendel was no problem, shell casing ejected flawlessly, so I am at a loss.

The other review said he was at a loss understanding the FTF's.Let me explain I have not yet found a Grendel mag that worked correctly at first. I take apart all my Grendel mags when I buy them and take a wire brush to their insides. A good 5 min rubbing each mag removing all paint inside if the is any.Heavy oil the insides with a Nickle Boron type oil only. dry them / rub hard another coat on wipe dry and put in the oven 250 degrees for an hour (mag body only) have some good gloves when you do this by the way, remove let'em cool down a bit still too hot to handle bare handed and put another coat of oil on the inside let them completely cool to room temp. Oil 1 last time including the follower and spring wipe dry all put light coat on front and back side of follower with your finger / reassemble all I did this to all my 6.5 mags and never again have any problems. All steel 6.5 Grendel mags should be treated with nickle boron containing oil and bake it into the steel smooth the insides first and they will be perfect from now on

Okay, I have a bunch of these and haven't had an issue unless I load them to 24 or 25 rds. These are 23 rd mags, not sure why but all my issues disappeared once I under load them by two.
