Nathan FosterHi Randal, good to hear that the factory barrels are going well. Ruger has come a long way in recent years, showing a major improvement in overall barrel quality since the release of the Hawkeye rifle.
One thing I need to say guys, is that of late the subject of fast change barrels has been coming more and more to the fore within the realms of my own research and among peers. One of the problems people are beginning to find is that the faster you can change the barrel, the more there is to go wrong. Rifles like this which are a bit slower to change out due to lock nuts and the need for head spacing can at the end of the day prove to be more secure and reliable long term. So there are a few pluses to this type of system.
I also like the fact that as a collapsable rifle, it is the butt that folds away without moving the barrel. I just cannot believe sometimes, that an engineer would come up with barrel removal as a solution for making a take down rifle compact when the butt is the most reliable means of making a rifle compact without effecting the zero.
To be honest, if it was my rifle, I would leave it in .308 and focus on becoming highly proficient with the rig. There is a great deal you can learn within a caliber, such as how different bullets perform on game at varying ranges etc. Being able to change barrels in a relatively painless manner means that you can go all out, wear out a barrel and then replace it and carry on. The more you know the one cartridge the better. There is much to this that I feel unable to discuss here and do not want to go down too many rabbit holes. But in brief, although the .308 will not shoot as flat as your Creedmore, it will teach you a great deal and if you stick with it, it will repay you in kind with a heavy payload. I see no reason to swap between the two. If it were the other way around, the Creedmore would teach you that although this cartridge has a very flat trajectory, trajectories are not the only factor that we have to take into consideration (which crosses over into what Bryan talks about and also the 7mm Practical and Magnums thread).
If you want to effect a great deal of change, I believe you will need to adopt a great change in bore diameter, hence why our friends are suggesting the likes of the .243 and .358 (Bob basing his choice on past experience with the Federal). Who would have a tactical .358? Well, if you read O'Connors early works, the .351 Self loading did prove to be a favorite with police in its day. I am a great fan of accurate .35's for hunting.
The advice offfered by myself and others is obviously just shooting the breeze. Perhaps you want to explore the Federal. Don't let us cramp your experimentation. Having said this, please refer to the cartridges book for potential COAL's for your proposed Federal. It would be a shame to have to single feed it.
