Has anyone found problems shooting Rainier or other plated bullets in the 1400 fps range? I've seen the cautions about keeping the bullets under 1200fps, but I've seen no problems using Rainier 125g JFP and AA#5 powder pushing 1400 fps. Though Rainier states the 1200 fps caution, it doesn't say why and then provides reload data using AA powder all the way up to 1900 fps. Am I missing something? My barrell on my 686 and Model 60 seem clean, and the accuracy is good using AA#5.
