Sierra MK\'s Ballistic Coeffecient: The Truth Wanted
Experiencing confusion! Gonna build a LR critter getter using high BC bullets. I want to use Sierra MK's in either 6.5 or 7mm. Now I have read several diferent documents that post the 7mm 168gr MK's BC @ .633 & .627 and I believe my Oehler Ballistic x-plorer gives a .633, yet at the Sierra website they give only .488 for that bullet. Is that a misprint? Anyone got the true answer to that? (I intend on calling the Sierra tech line on Monday, but can't wait)
Gonna build either 6.5-06 Imp or a .280 Imp based on the higher BC. I am determined to use MK's as Primary bullet due to reputation, $$$ & availbility. I am aware of very high BC VLD's, but don't want to go there.
