I recently purchased a New S&W M&P FS 9mm 4.25" to replace a 30 year old S&W 459. Due to recent shortages... I picked up... Grabbed what I could find and felt lucky to find anything! Power Pistol CCI 500 pistol primers Rainier Plated 124g Round Nose Mixed brass Got load data from Rainier by calling and e-mail. Confusing because I got two different responces. phone call: PP 5.6 to 6.4 e-mail: PP 4.8 to 5.3 Loaded upsome test rounds starting with what was given to me in phone call. 5.6, 5.8, 6.0, 6.2, 6.4. At 15 yards no keyholing and no high pressure signs on brass. Groups looked like #0 buckshot. 6" to 8" at 15 yards and all over paper??? Any good advise? Loads? My old wore out S&W 459 got better groups than the new M&P. Not happy so far with new M&P.
