Re: long range rifle advice
Do you have someone that's going to teach you to shoot long range?
That's a much more difficult task to learn than handloading. Especially on your own.
Since you have no budget limitation, skip the factory action and go for a custom. Stiller, Borden, Bighorn, or similar will be money better spent than fixing up a factory action.
Krieger is a good choice, but IMHO Shilen is a step down. I'd also look at Rock, Lilja, and Brux. Cut rifled seems to be more popular lately, but good button rifling has proven solid performers.
Don't forget all the accessories. Range finder, Ballistic Calculator, Anti-cant device, Weather meter, Angle Cosine indicator.
