Is it possible that the ogive could vary .030" on different lots of Bergers?

[QUOTE="woods, post: 432632, member: 6042"] Typically the comparator insert holes are .011" below caliber. I just measured the comparators I have and got these results caliber / comparator hole size .264" / .253" (both my comparators measured .253" but on one of them the hole narrowed to .252" further in) .284" / .273" .308" / .297" .338" / .327" .375" / .364" as measured with pin gauges [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1908.jpg[/IMG] why they didn't make the holes .008" so they would hit on the same point on the bullet ogive as the lands do, I don't have a clue! Now the seating stems have much smaller diameters where they will first hit the bullet as evidenced by this 30 caliber seating stem from an RCBS standard seating die (the only one I will take apart and measure since I refuse to take my Competition Seaters apart, they are working too well) [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1909.jpg[/IMG] Bullets vary greatly, case in point these 2 Accubonds from the same box [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1901.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1902.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1904.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN1905.jpg[/IMG] But I've always heard Bergers were amazingly consistant. Maybe not. [/QUOTE]
