Hi Jack,
Thankyou for your input, yes I have near a full box of the Sierra 70 Grn MK's so I will start with them for now and I will try to get some of the heavier bullets later.
In light of your experience I will try loading a few with each of the powders you have suggested and see which does the best, something like 15 rounds with each powder and three different charge weights with each powder. That should give me an inlking of what it likes
........................ I hope
