[QUOTE="nicholasjohn, post: 1616028, member: 109113"] There was a reply to this thread that discussed bore-scoping the gun to see what the throat looked like. I once did a chamber cast for this purpose, before I got a bore scope, and it worked reasonably well. It was on a Sako .22-250 that my buddy got pretty hot on a prairie dog shoot, and I couldn't get a bullet into the lands while still in the cartridge case when using the Hornady tool to measure where the rifling started. I put the plug in the barrel a couple inches ahead of the throat, and it was easy to see where the rifling started on the Cerrosafe cast. It was about 1.75" down the barrel from the mouth of the chamber, and I could even see the alligator skin texture on the part of the casting that had no rifling on it. I think Brownell's probably still sells Cerrosafe, and it's pretty easy to use. Getting the right funnel is the only trick to the process. I used an aluminum funnel to get the molten metal into the chamber. This stuff works exactly like the directions state. That barrel made a very nice tomato stake. [/QUOTE]
