[QUOTE="J E Custom, post: 1060246, member: 2736"] Sorry it should read FOR each barrel. And like you said, you could have many different barrels for one action. "BUT" as you also said, you must re zero every time and by taking the scope out of the rings you must set the eye relief and you must level the scope (Which could change your Windage on longer shots) that is why I recommend leaving the scope in the rings. I like to leave the scope in the rings and separate the scope rings from the bases without disturbing the Base. The problem with different cartridges, is different zero's and now that we have better fitting picatinny bases and rings you should be able to remove the scope to switch barrels and install the scope that was zeroed with that load/cartridge and it should remain very close to the zero for that barrel and cartridge. IF you use the same scope for every barrel and cartridge, you will have to sight in every time and that takes time and money. I just don't see the economics of having one action and multiple barrels with all the problems and cost of having a switch barrel set up. If you run the numbers on all that Is needed The only real difference in cost is the action and if you have to have a different bolt face that will require a different bolt, Mag follower and magazine. The main concern I have is the increased chance of making a mistake assembling the rifle and having a problem. Once a rifle is assembled and tested there is little chance of a mistake and that would probably be a load issue Not the rifle. Again, I don't want to talk anyone out of what they want, just trying and discuss all of the issues related to it and let the builder make up his mind what is important and what is not to him. It is all Opinion, and we all have one. J E CUSTOM [/QUOTE]
