If you are looking for .45scp that is hotter than Wincherster, just about any other brand will do. They down load their white box ammo by about 30fps for some reason.
For top quality hot .45acp, go to AIM, and look at their MFS .45acp. It is about the best you will find, and it is about 130fps faster than the Winchester. The +P is even hotter, but I have not tried it.
We sell this stuff as fast as we can get it with people constanly telling us how great it is. I have shot it and found it to be pretty dam goos as well.
I haven't looked at Ammomans prices, but the MFS should be cheaper.
Edit, if the box does not say Match, ammo, it is not match ammo. Match grade in thedescription without it being marked on the box is just to get you to buy it thinking it is better than the regular ammo it is. It looked like regular Federal ammo to me.
