I have 10 of these babies. Takes a little time and effort learning to use it correctly, but you will get a "feel" for it. Each bullet diameter makes a difference...the .204 Ruger doesnt require as much force as the 30-06 or 7mm. Take MULTIPLE readings...at least 10. Dont ram it up in there and dont ginger cake it either. I push hard enough to "just touch" the Lands. After my "AVERAGE", I make up "Dummy Rounds"...use a felt marker to "paint" the bullet...place in the bolt,,and close her up. Remove softly and check for marks in the "paint"...each Gun likes a different jump...and here is where the fun begins ! Takes a while, but it will be worth it. PLEASE REMEMBER !! Changing the OAL of the Cartridge WILL change PRESSURES. If you have been using 40 grains of powder, loading to the BOOK OAL and recommendations...and you increase the OAL..your 40 grain load COULD BE dangerous !! Back off 10-15% and start a New Load. ALSO, you MUST use the exact same bullet, from the same manufacturer, from the same Box...as you intend to use in your reload. A 140gr AMAX and a 140gr Nosler Ballistic Tip ARE NOT THE SAME bullet. Different OGIVES...different bullet lengths. Each time you switch bullets, you must take a new reading. I have my OGIVE reading written on EACH box of bullets...and just because you have a .308 compass and your buddy has a 308 compass..does not mean they will shoot the same OAL bullet you measured for yours. One last thing...your FIRST step is to measure your guns magazine...trust me...a 2.75" cartridge will not fit a magazine that measures 2.60" ! ..unless you want to turn your bolt action into a single shot.... Hope this helps
