I agree with the YodaVader's post that Savage barrels often copper-foul. It was my experience, and I've seen it at the range affecting others. Once my LRPV shot it, it did no longer copper-foul and shot even better than originally. It shot many 1/3 MOA groups at 300 when I didn't make mistakes, and it had a load that it liked. But one thing I noticed right away with the PacNor...it seemed to shoot well, cold or warm, from the get-go. And what was even a better suprise was when working up groups...I couldn't find a 'bad' load for it. It seemed , with the exception of 58 Gr V-Max (which still shot below MOA), every combination of components and powder charge shot 1/2 MOA, and a lot shoot better. It was hard to find an 'ideal' load, as many resulted in the same groups. My expectations for performance with this barrel on this action were lower than the result, but some of this is surely attributable to Lapua brass and the fact that 6mmBR Norma is such an accurate and forgiving cartridge. The fact that you can drop a primo barrel in so easy, is so very attractive.
