I enjoy mine. Easy to load for, fun to shoot. My only goal is accurate hunting subs, and the 400gr Makers do that well. I’ll hunt with it this year and next year will be a Whisper.
Sounds like a friend and I are going to jump into the 510 whisper. I’ll likely get a desktop lathe. I’ve got an email into Maker to see what twist is needed for the 1,000gr bullets. After that it’s a text to Bartlein.
