I just went into the shop because I was sure I could get more than 40 gr. of IMR 4064 in my 308 case. Nosler and F.C. will hold over 49.gr. without tapping to settle the powder. If I tap the cases I can get right at 50. gr. of IMR 4064 in them. I wish I had Some Winchester to compare but I don't. I'm still sure Winchester will hold well over 40 grs. of 4064. Now before someone says my scale is off I used two scales, a Dillon electronic and RCBS Load Master. They are the scales I use for my loading. I was using an RCBS funnel and not tube feed the powder.
