Re: 3 store bought or.. a custom??
Northman resides in Norway. Probably cheaper to buy Schmidt & Bender or Hensoldt/Zeiss than NightForce. Remington is very expensive over there. On the bright side of things, shooters can own supressors without any problem.
Sako TRG 22 with a suppressor, accessories, top notch scope probably all for the price of the Accuracy rifle alone.
Doing a custom Rem 700 would likely cost more than the TRG. Gotta buy the rifle, and pay import duty. Guy I corresponded with in Norway 3yrs ago owned a PSS or Varmint Special and paid about 2x list for it from the Remington "agent" plus had to pay import duty. Yet, Norwegians can own only about 5 firearms, so may as well buy & spend for what you want to own. I recall this guy having difficulty getting a 20moa base for his rifle...
Point is a Rem 700 is not in the same league as a Sako TRG22, or TRG-S. For the money AI represents if you start with the Sako, you get superb quality and have funds to have Kieger or JR in Scotland build the barrel you want. If you happen to own a TRG-S in standard ctg chambering, you can swap bolt bodies and factory barrels.
M995 sporter and a TRG 22 or 42 would make a set of rifles you could swap barrels with and own additional barrels to enable using a variety of cartridges, if owning additional barrels does not comprise owning a "firearm". Even the 22/42 magazines will function, with minor alteration, in the TRG-S. only Sako offers interchangeable bolt-bodies and drop-in triggers available for direct sale and often in-stock; at least in the USA.
If you could only own 5 firearms, would be nice to have a rifle that would accomodate any round with ctg face of .473, .530, or .580, wouldn't it? Might have to buy a new forend stock piece to adapt a TRG-22 for magnum or lapua magnum magazines, in addition to the barrel and bolt body, but the point is, it can be done. Accuracy, Value, and Versatility are the hallmarks of the Sako TRG-22/42.
