I am kind of disapointed that there has not been more response, though I guess most of the experience here is with English rifles. I talked to Mr. Searcy previously, about it and he gave me just the bare bones information. I have read on this forum and others about shotgun actions, even reworked ones like the Merkle, not holding up to heavy use in large calibers. I recently talked to a well known expert on double rifles and he advised me that these type of guns shoot loose fairly quickly. I like to gather as much information as possible before making what could be a large investment. I have no reason to doubt this expert, but would like to hear from some other folks that also have had first hand experience. I shoot quite a lot, and if I had a double, trust me, it will be shot a lot. Many Merkle owners are very happy with their gun, but how many have actually shot over 500 rounds through them? Getting real information on this subject, as opposed to opinions by folks with no first hand knowledge is pretty hard to do. This is not written to try to offend anyone or their favorite brand of rifle, I am just trying to learn enough to keep from making an expensive mistake!!
