[QUOTE="Blackhawk, post: 2032359, member: 105459"] [I]I have found out several things using the Horandy( old Stony Point)Bullet comparator. 1) Start with a clean bore and rifle chamber ( you'd be surprised at how many people do not clean their rifles before using this tool) [/I] 2[B]) Important:[I] I recommend [/I][/B][I][B]not using the Horandy generic all in one case[/B][/I][B] , but rather after fire forming your own case drill your case head through using either a (Letter L or 19/64") and tap for a 5/16" X 36 TPI thread. ( how to directions can be found on the internet ) The Horandy generic case will not fit your rifle's chamber exactly and may cause problems resulting in erratic measurements. ( If using the Horandy case look at the cases shoulder and see if it is showing marks which will appear as concentric grooves. This is an indication of rub and a potential for error)[/B] [I] Now that you have a fire formed case sized exclusively for that specific rifles chamber you can proceed. 3) Take a bullet sample and make certain that it will easily slide into your shell case. If not I suggest the use of the Sinclair Gen 2 expander die and the correct caliber specific mandrel. 3) When seating your bullet up against the rifles lands I use a small dowel placed from the muzzles end to make contact with the bullet tip. After contact make certain that the tools brass thumb screw is secured and push the entire assembly tool case and bullet from your rifle. If done correctly your bullet will stay seated in your shell case. 4) Make certain that you are using the correct Horandy bullet comparator insert. Note: There is nothing in the instructions stating that you need to use the stated insert is is only a suggestion based on a starting point. If your bullets ojive does not engage this insert quite right then find an insert with a better fit. 5) Now what I do is take an average of three different readings trying to be consistent with my readings and call it done. I know that you may experience some level of frustration but the key word here is consistency. (As suggested the anvil base used with a quality digital set of calipers will help) [B]Just relax stay calm and please try my suggestions, as I think that they may help .[/B][/I] [/QUOTE]
