I have been trying to get some Nosler 70gr RDFs to shoot and I tried some 748 today with both the RDF and 69 TMK.
The RDF had some decent SDs (8.8) but absolutely horrible groups, I didn’t measure, but 5” would be generous. The TMK had a SD of 1 for two separate charge weights and the third was 0, but similar groups to the RDF.
I shot a control group with 52gr MK and it was typical of the gun @ 0.4”.
Has anyone experienced anything like this before?
