Traded away a mint two year old S&W Mod 686+ 357 Mag and 150 bucks for a 1975 2.5 inch S&W Mod 66 (no dash) 357 Mag at the LGS today. Once all the paperwork was done and all the property/money changed hands--I went out back and proceeded to shoot the "new" Smith along with a 1968 2 inch S&W Mod 10 38 SPL. I tried a bunch of reloads and the "new" Mod 66 seemed to like my +P 158 gr hardcast/CFE Pistol loads the best. I will have to experiment a little more with the Mod 66 to fine tune that loading so it shoots closer to POA. It was a great way to enjoy the day before the oncoming rain hits us (again).
