If you are building a 308, I take it Italy has changed its laws about civilians possessing war calibers? When I served there with the 509th Airborne in Vicenza years ago, it was against the law to have for a civilian to have a 308, 223, 9mm or 45 without special approval.
With the 308, you might find the 5-22 NF a better match.
The problems with building a rifle here are principaly two;
The "Banco Nazionale di Prova" and the "Catalogo Nazionale delle Armi"
The first is essantailly a testing facility that must give the ok on ANY mod performed on a firearm that does not alter it's original form. Be it something as simple as threading for a brake, (which should actually go throught the Catalogo too, but they close a blind eye on that one)
If you do so much as change barrel length, profile or type, action, mag capacity etc. it must be re-entered into the national catalog as if it were a "new" weapon.
In order to be cataloged first it must pass the testing bank, then the descision is made to accept it on the catalog.
The process can take several years. It's usually about a year for a commercialy made firearm. We still don't have the .17HMR nor have the WSSM's even been heard of here yet.
Maybe by Christmas we will have the .17HMR, I doubt it.
I will not alter the rifle's original form so as not to have to enter it to the catalog, but it will have to go through the testing bank.
That's why I need to start with something that is very close to what I want to end up with.
I couldn't tell you when the ban on military cartridges was lifted here, I think they still enforce in in France, maybe Spain too.
I'm still not sure on how I'll go about this project. If I can fit a Sako M75 action into the McMillan stock I will just buy the Varminter and be done with it.
Otherwise I'll start with the action(which is considered to be a firearm in itself) then add the barrel(must conform to one of the cataloged models that action is found on) then the stock(no problems there)
I hope it all works out, if not I can always just buy the factory rifle and accurize...
Here in Rep. of Ireland the law states that you may have rifle calibres up to .270 inch for target and hunting, but the police enforece an unofficial ban on the .223 Rem , 5.56 Nato and for some strange reason the .222 Rem. They enforce this ban by refusing to issue firearms licences for these firarms even though they have no right to.
Why not just go to the Remington Sendaro in 308, 270 Win, 7mm Rem Mag, 300 Win Mag, 300 Weatherby. If the Winchester Short Mags get approved, then go to the Win Coyote in 270WSM, 7WSM or 300 WSM. Either way, US $ cost is $700 or less, bed the action, recrown and trigger work for under $200 and no visible or testable modifications.
SWFA has the TASCO Navy Seal super snipers scopes again now for $299 or $399 and those are mil dot and hell of a scope for the money. Never heard of a bad one, originally sold for $900. They come in a fixed 10, 16 and 20X. They will work great for what you are trying to do and put the other $ into bullets and shooting.
