Here's a neat idea to test several loads in your gun and choke to see which one patterns best. I just bought and Indian Creek Choke for a 12 ga. and wanted to find the load it liked best. I started inquiring from my friends, co workers and relatives as to which ammo they were using. Of course they all aren't the same so I had them give me a round or 2 of every different combination I could find someone using. I swapped them 2 of what I use for 2 of what they use etc. In no time at all, I have 11 different makes/loads of 3" mags to test in this new choke and I only purchased 3 brands of ammo myself. Now I just have to get a bottle of aspirin for the day after all that recoil!!
