I also shoot a lot of the CCI Blazer and WWB, but they both continue to go up in price. Most of my trips to the range now consist of 50 rounds of 9MM CCI Blazer thru my S & W 3913 (will now use my FNP-9M as well), 50 rounds of 38 reloads thru my Marlin lever action, then 200-250 rounds of 22LR thru my P22. Just looking for economical ways to be able to keep shooting.
I bought a Saiga 7.62 x 39 about a month ago for the same reason: shoots cheap ammo and is lots of fun.
I picked up 2 boxes of the Monarch Blue Box 9MM last week, so I will give it a try Saturday. I know it will shoot in the 3913, but not sure about the FNP.
