I have been doing my own person research online for the different calibers, and well I am even though I am not currently a Gun Owner myself I was curious as to what other Firearm owners would have to say about this. Basically I was looking at maybe down the road for 1 Bolt Action Rifle, and a Semi-Auto as well, and well the two main calibers that I narrowed it down to is the .223, and the .308. Both Calibers seem to be reasonably priced for the Better variety of Bold-Action, however I was only looking for one other those in particular. My main Issue is that they are both pretty far up there as far as the Semi-Auto's go, but the .308 are quite a bit higher than the .223 Rifles. Now I do realize that If I were to get The Semi-Auto for the .223 that can be modified also to shoot a weaker .22LR, but still the cost is a bit up there. Would anyone like to give me any suggestions, or help me out on this one? I was also thinking in terms of Ammo Cost, and Availability too under the grounds of a Minimalist variety of Caliber.
