Hello, new member here

I'm new to PCP airguns. I've shot with various pellet/bb buns and other firearms for over 40 years. I recently purchased a .177 Marauder for backyard target shooting. I'm just starting to play with suppressors and upgrades. It would be great if I could connect with folks in the Sacramento, CA area to discuss best practices and lessons learned :)

Any recommendations for the best projectile for accuracy shooting?
