mini grease groove bullets

[derskeeter]

I have a roller in 45-90, and I've been looking at the BACO 535 grain bullets. Because of case length issues with the roller I was going to go with the standard bullet, not the reduced front band one. Then they came out with the tapered front band bullet. That one interested me but I thought I would wait a bit and see if anybody developed an opinion of them. I haven't heard anyone talking about them but I thought I would give it a try. Then they came out with the mini groove bullet. I figured they were for the smokeless crowd so didn't look at them. Now I see in the last Black Powder Cartridge magazine that the world championship was won with these bullets. Opinions, thoughts? I'm so confused. Please don't tell me to try them all because I just shot my first silhouette and have enough to figure out.
Thank you
