L3I Angled billet mag review

[David Lott]

This is not really a review per se but since I had a lot of testing to do I thought I'd give it a fair shake, Derek Webster ran it in a few matches that ran perfect after adjusting it to his MPA BA comp chassis. When I tried it in my Foundation Centurion originally I had a few issues but today I thought I'd give it a good adjustment and see what it could do. Turns out it works awesome once ajusted correctly but like everything else 700 rimfire we have to "make" a rimfire work in the design of a centerfire rifle so all in all I think it was a great idea that they came up with and absolutely flawless feeding for 300 rounds today.I Actually shot some of the best groups today simply from not worrying about possibly having a feeding issue, strongly recomend them.

Your chamber face clean? The issue I have with getting the magazines perfect, even if they feed flawlessly is if any angle is slightly off at all, you'll start accumulating a smidgen of shavings.

The stinger mag has also been flawless in my mpa chassis. I have only used it for casual shooting off the bench, but after one slight adjustment it has ran 100 percent for hundreds of rounds.

Yeah even after getting them running and adjusted seeing quite a bit of lead shaving on chamber face in mpa matrix pro ii. None at all with vudoo polys so now back to running those. Shaving is on bottom of chamber which implies they are too low but there is almost no more vertical play at this point. Tried getting them higher and then they tend not to feed and hit top of chamber. Open to any tips as I would love them to work…

I have the same problem with my poly mags. Shavings on the bottom sometimes. And sometimes the rounds go high and the bullet gets jammed on the top edge of the chamber.

 

[littlepod]

People put velcro on their poly mags thinking it'll help wedge the mags so that if there's pressure on the mag it won't cause a feed issue, but the velcro/wedging changes the angle of the magazine slightly causing the front of the mag to slightly dip which then means the rounds get a little bit of shaving when going into the chamber.

@David Lott Dave that pile of brass looks like a few more than 300 rounds LOL!

I ran the stinger mags in my XLR Envy when I was shooting a V360, once adjusted I cycled the same bullet 10-12 times and there was no damage at all to the lead. Now a buddy of mine running a V360 in a stock(not sure which brand)could not get the stingers to feed, I had an old XLR chassis I got in a deal here and gave it to him and they feed flawlessly with minimal tuning.
I think these mags are awesome but do not work so well with some stocks and chassis.

I average one a day with no problems, so the brass piles up

Is this problem happening on the bench during normal firing?
