[QUOTE="MagnumManiac, post: 339418, member: 10755"] Although the throat of a chamber is cut by the reamer, they differ and are not bullet specific, in your case your throat is long. You do not need a reamer made, what you need is a throating reamer which is different in that once the chamber is cut it is used to obtain the correct throat length as to your specs. The only way to shorten it is to remove the barrel, cut the desired amount of threads from it and re-thread/re-chamber with the throat length that you want. This is easily accomplished by measuring your mag box and setting up a dummy round to suit and instruct your GS to cut the chamber so that there is .010" clearance to the lands. This is neither difficult or expensive to do, but it will make the stock to barrel fit look ugly in most instances. If you're happy with the way it shoots and the calibre it's currently in, then just shoot it until you need a new barrel and make the new one to your specs when needed. Unfortunately you will never get the perfect throat length for all bullets types and styles. I must admit that I have never found a long throat to be detrimental to accuracy because there is always more than one sweet spot with every bullet I've tried, one up close to the lands and one further away from them. gun) [/QUOTE]
