[QUOTE="woods, post: 370303, member: 6042"] There are definitely differences in ogive curves Example, here are 2 ea 200 gr Accubond bullets that weigh within .5 gr of each other [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1901.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1902.jpg[/IMG] but have a comparator measurement from bullet base to the point where the comparator hits the curve of ~.016" [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1904.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1905.jpg[/IMG] The holes in the comparators are not caliber size as Fitch is saying, this 30 caliber comparator has a hole that is .297" [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1908.jpg[/IMG] Now on a slow curve like on the bullet the linear variation that occurs in between where the comparator hits at .297" and where the lands hit can have an effect on seating depth measurements. Same with a seating stem except much worse since the best I can tell, the first point on the inside of this 30 caliber seating stem hits the bullet at a diameter of .260" [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1909.jpg[/IMG] That was on a regular RCBS seating die. I could take apart one of my Redding Competition Seaters and measure but I hate to take one apart since they are all set for my rifles. [/QUOTE]
