I ran it thru JBM ballistics a couple years ago at 1000 elevation. I am using Win brass with 46.5 gr Imr 4064 and a cci#34 primer. Gettimg the best group right at 2.810 coal. I am planning on some testing with a new 26" barrel. I have a 500 count box of the 155 palma's and 8lb of powder. Waiting on the weather to break. Gonna load some with IMR4895 and see how it does. Maybe some 748 if those don't work
