I've been doing some load development with my new Sako 85 Finnlight in 300 WSM
topped with an NSX 5 1/2x22 x50. I 've worked on a couple loads for 180 ETips and 168 TTSXs using H4350, Norma brass, GM215M primers. The brass was trimmed down to 2.085 (2.10 max). I'm necksizing only with a floating bushing using a Redding die and Redding competion bullet seater. My groups are running about 1.5" at max and near max loads. I'm going to try stepping down a couple of half gr increments and some different seating depths. These bullets are more than .10 off the lands due to magazine length.
I wonder if it's the rifle or the load or both? I have been very meticulous about the loading procedures and they *should* be better than average loads.
I was wondering if there is anything I could do to accurize the rifle? Pillar Bedding? Pressure points? etc. Any comments or suggestions?
