Now now Rangefinder, no reason you can't be civil. If you want to tell him that his bullets can be pushed to any velocity without knowing who made them or how they were made be my guest. Most hardcast bullets can, which was my point. Missouri bullets for example has some 357 bullets which are recommended only up to a certain velocity. For all any of us know he is shooting swaged bullets and even 5 grains of red dot will be pushing the envelope.
New gun, same ol' shot.
