I shoot several 6MM PPC's, none are Sako's, but there are some similarities. You have a standard .265" neck 6MM PPC. Sako makes brass that will fit perfectly, get yourself a set of Lee dies load the cases and have fun with the rifle. If you feel you need better equipment or components, Redding type S bushing dies are better, and cost over a hundred bucks. BR 66-68 grain bullets are running $170.00 per thousand plus shipping. Federal 205M primers are the best. VihtaVuori N133 is the powder for best accuracy. Don't waste your money on things that wouldn't make the rifle shoot any better. Give Sinclair a call at 26-493-2530 ask them for a catalog. Its full of bench rest things you don't need, but it has a lot of information and is worth reading. Welcome to the accuracy world. Here's a picture of a high dollar target, just look at the holes.
