I got a chance to try out some 147gr round nose today before work. I had a few different loads I was trying with other bullets and only had 25 of the 147's. Not nearly enough to really establish their accuracy but I did find that they seemed to be hitting about 1" or maybe even 1.5" higher than the 124's. The biggest difference I noticed is the difference in recoil. Not nearly as snappy as my 124 loads. Very controlable and very fast back on target. Can't wait till my weekend comes to try out a few boxes.
