A chronoed and field tested 6mm load

[Classicvette63]

Over the weekend I had time to chrono the 6mm load my niece was going to be using for deer season. The data is as follows:

100gr Sierra boattail: 36.0gr IMR 4064 (this load was safe in my rifle, you results may be different) Federal cases and primers

F.P.S.: 2805, 2785, 2768, 2817, 2798, 2810, 2832, 2838, 2756, 2813.

Avg.: 2802 Ext spread: 81.47 Avg deviation:26.22

3 of the cases suffered partial case head separations. (I knew these cases had a few loadings on them. The hunting rounds used new cases.) I didn't note at the time which ones separated but thinking about it shortly afterward, two happened back to back and one happened late in the string. They may have been the three lowest shots. If so, the E.S. and A.D. would be much less.

These loads are very accurate out of my 760 pump. I took a doe last year with this load, breaking about 13" of spine. She got here first deer this year with a shot broadside thru the ribs. Neither deer moved from the spot.

Thoughts?
