I am going to be doing a custom build with custom ammo. My cartridge length will be about 3.125" but require the .223 bolt head. I was originally looking to use a 700 long action for this but others have discussed using a Savage action since the bolt heads are replaceable. I happen to have a few Savages and I hope I am not going to get sick but I just turned loose of a .243 Model 11 for 250 bucks... I hope that was not my donor that just left!!! I have a .300 RUM 116 that would work great other than I am not sure there is really a market for my barrel, stock, and bolt face and hate to bastardize a good and marketable, all stainless rifle. I also have a .308 FCP and the actions are certainly different. the mag in the FCP would barely accommodate a 3.00" round. the action could probably be made to work but.... So that leave me wondering if my 243 would have really worked anyway and if not, what other options might I have? Obviously trying to watch the budget. Someone else suggested the Savage Stevens 200 but again, I am not sure what models and what chamberings had what length actions... My current 300 RUM is not accu trigger but I was going to work this one over and see if I can get to my target of a smooth 1.5# trigger. If not, that would be an added expense.
