[QUOTE="SidecarFlip, post: 1115165, member: 39764"] First thing you need to do is look inside to see what's in there. For that you'll need a borescope. You can spend 700 bucks for a Gradient Lens Hawkeye or go to Harbor Freight and get yourself an 89 buck inspection camera. Thats what I use. It has a led light built into the end and while it won't fit down your bore (It will fit down a 50 cal bore), it will allow you to inspect the receiver, the barrel face and where the cartridge brass meets the chamber plus it allows you to inspect the lands. The light is bright enough and the resolution is good enough to see at least halfwau down the barrel with no issue. It's a nice tool to have plus you can plug a monitor into it if you want a BIG picture. I had the exact same issue with one of my sticks. Turned out ther was a small burr at the beginning of the lands. That was hanging the pill and pulling it out of the case. I used a Tungsten Carbide scriber and worked it out (with the cam inside so I could see it clearly. After that, I loaded to the lands and got my LL measurement, no issue. You have some obstruction inside and the only way to see it is look inside. You should be able to long load a dummy round (I use a bushing die with a bushing that will allow pill movement without too much resistance load it in, close the bolt (the bolt will push the pill to the lands (an d the pill will 'engrave the lands, you'll be able to see it on the ogive near the base). Retract the bolt and then measure your LL distance using the appropriate gage and a set of calipers. Never neasure from the tip of the pill to the base of the brass, always measure on the ogive with the correct gage. Hornady sells a set or you dan make your own, if you have machining skills. Typically, a 30 caliber uses a 0.040 gage. Do the seat to lands at least 5 times and when you get a donsistent measurement, thats the one you go with. I do mine 7 times and add them all and divide by 7 for the average, I use mine all the time to insure I've cleaned the bores of all copper fouling. It's amazing what BTE can doo (not a plug). I can take a fouled bore, clean it with BTE, inspect it with the cam and shes as clean as a whistle.... Good for other things like looking inside a die to make sure it's not scored ot looking in your dar engine to see whats inside....lol [/QUOTE]
