Cody, trust me on this, I am the king of getting rifles when your broke. lol. Seriously ask Dan.
APK would be right. Him and myself started the exact same way you are. We struggled to get the money, and wanted every bit of performance and reliabilty we could get. If ever there was a time for "The Best bang for the buck", we went there. Two years later, and now an adult, I've seen that the road we took couldn't have been more smooth. We each own two excellent rifles now and have fun every single time we go to the range, whether the groups are a personal high or low.
Actually, it's a relief that you are considering .22-250 Rem. One of those excellent rifles I wrote about above is a Remington VSSF chambered in, you guessed it, .22-250. It's my varmint gun, and might as well be my target gun as well. You probably have shot the caliber before, but a word of warning, 22-250 is one of the most difficult cartridges to load for. It's a finicky caliber, and the time you spend behind a press reflects that when compared with the easy .308 Win. Enough talk of reloading (you may not do it yourself), I'll put in my 2 cents.
As ready as you are to built a custom rifle Cody, my opinion is that you should consider production rifles. You have listed a variety of things you could replace, and I feel that a good production rifle will be cheaper than the custom job. If you are not a serious target shooter, and this is your first serious rifle (We've all had a Wal Mart .22 lr...), the factory accuracy of a quality rifle should suffice. I told you two years have passed since I bought and outfitted my first "real" rifle, and if I said I could match the performance of the rifle I would be lying. Though I've learned much about markmanship, shooting sports, reloading, gun care etc. in those 2 years, I still have a long way to go until I can appreciate a custom rifle. I hope you understand you will probably experience the same thing.
I would suggest that you do indeed check into 700 BDLs because if in the future you choose to have custom work done on the gun or buy accessories for it yourself, the Remington will have more options than the Weatherby due to it's popularity/design. Weatherby is a good gun, but I've heard the rifles manufatured in Belgium walk all over the Japanese ones. Be careful.
Consider a Remington VS or VSSF. Their heavy barrels and HS Precision stocks make accuracy very affordable. Believe me, I was so happy with my first Remington VS, I bought the second VSSF without shopping elsewhere.
Whatever you decide on, here's a list of the things I would consider:
Synthetic stock (Humidity in PA...)
Adjustable Trigger (Reminton is excellent, can adjust to about 2 lbs safely)
Free floating barrel (The harmonics, or vibration, increase accuracy)
There's the general few that I wouldn't pass up.

Good luck on whichever road you take Cody.[/b]
