Hello all,
I wanted to share my experience with two items with you. First of all, when I came to my range today I bought a box of Whtebox Winchester BEB ammunition. I include the link
here so you know which ones I mean.
They performed really bad, in all of my magazines, and the magazines are ok now (thanks GT

)so I am sure it was the ammunition. When chambering the first round it felt like it wasn't going in smoothly, the toggle just didn't feel right. I could not shoot a complete series of 8 without jams. The funny thing is I used conical Winchester ammo before (super X or something the one in the silver box) and they performed fine. So this particular stuff must have something special about it.
Another thing I tried out and can't recommend is
this particular magazine
I ordered it because I wanted to have a cheap one that could keep loaded all the time and wouldn't have to worry about the springs wearing out. I don't want to do that to my good magazines. Turns out this one doesn't even go in the gun! So if you're considering a new magazine, stick with the mecgar ones and don't go for this one
