The only "shot" I can tell the difference between 100 and 147 is something that requires dialed-in accuracy - 4 inch plates at 30 yrds, for example. Though that's probably more imagination than reality. If I'm using 100 gr I'll go with heavier spring in JP SCS, and lighter spring with 147. As for dot bounce using different weight bullets, I never really see the dot beyond confirming I'm close to where I need to be. Watching too many B. Stoeger videos, I guess!

5 for LO, and 6 for PCC.

The Burris FastFire 4 has the option to set dot to 11 MOA. I've not had my hands on one, so can't speak to what the dot looks like, clarity, brightness, etc.

I go back and forth between 510c and pistol size like Venom. I'm going to stick with 510c for rest of summer and then see when weather changes how much I love that big open emitter. As for Venom, it can be a great 45 offset sight if you decide to go that route.

My GMR-15 will run any brand mag except the Korean Glock clones mentioned above. It will not run those at all - will never feed a second round. I have had good luck with ETS, but twice cracked them when they hit ground during mandatory reload stage. Current set up is OEM Glock 33s for most stages, and a MBX combo for anything more than 30 rds. We had a "steel crazy" stage at recent wildcat match (spinner, two stars, plate rack, lots of poppers), and I was happy to not need reload - while listening to all the "real gun" shooters (hand gun!) complain about unfair advantage!
