I found some conflicting data today while putting together some .243 Win. with 85 gr. Barnes TSX and IMR 4350. According to The Lee Second Edition reloading manual, the starting charge for the 85 gr. Barnes X bullet using IMR 4350 is 43.2 grains, and the max load is 45.0 grains.
Hogdon's website has conflicting data though. The same bullet and powder combo there is listed as a starting charge of 43.0 grs, and a max load of 47 grs. compressed.
I'm not really concerned, since I've already done some load development with this combo and had no problems. I just thought it was strange, especially for a 2 full grain difference on the max load. I went with 45 grains, in case anyone is wondering. My last set with this combo was 44.5 grains and I felt I could bump it up a bit.
Has anyone else run into conflicting load data like this?
