[QUOTE="Philward, post: 2595538, member: 92604"] I read 2 or 3 other threads here about that, some just said neck size. I have the Hornady headspace tool that fits on calipers, used the 375 size. A note on Hornady packaging said for weatherby cartridges measure to a mid point between the radii, so I measured the difference between neck and case outside diameters and, subtracted, divide result by 2 and added result to the neck diameter. 0.391 was the result so the 400 tool might have been better. Talking with a guy here at work and I'm wondering if the distance from case head to top of belt is stretched from the hot loads, seems likely and I didn't measure that. All those cases are tossed in the recycle bucket anyway. The cases I shoot with 110 accubonds are good and all the once fired are good. [/QUOTE]
