[QUOTE="Coyote Shadow Tracker, post: 3089239, member: 116439"] RegionRat Thanks for blowing our picture of a piece of brass that we would reload. If we reloaded this Case without checking it could be a misfire or a problem with ignition. Fortunately, We check every piece of brass and ream the Flash Holes even though the Manufacture states they are good. I like to "Ream" the inside of the Flash Hole to give it a "Cone" for when the primer ignites there is a "CONE FLASH" that goes into the powder charge. Now Lapua has been using 0.062 Flash Holes over the standard 0.80 Flash Holes. Now this doesn't relate to Small & Large primer size as being larger for a large primer. I will try to put another Post with information from Lapua with data to show the difference on Flash Holes for the difference in SD where Lapua has correlated a change form 0.080 to 0.062 In the past I have been using 0.080 Reamers, but have not did any studies on SD between the 0.062 Reamer. K&M Precision Shooting manufactures both 0.062 and 0.080 Flash Hole Reamers. [/QUOTE]
