I'm sorry. You don't know what you are talking about. It would be nice if you state WHY you think the way you do, and possibly cite some sources, unless you feel stupid citing Marky Mark and "Shooter" as a source...
You are partly correct about AI and their bedding system. Accuracy International DOES make their own rifles, from the ground up. However, they ALSO offer a more cost effective route for those that like the stock and it's features.
The stock you refer to, the Accuracy International Chassis System (AICS), is designed for Remington 700 actions.
Here is a link to it.
Here is a review of a REAL Accuracy International Arctic Warrior in .338 LM.
Please note the line under the first picture. This means that it is, in fact, not assembled, but created.
Just because your Butler Creek or Bell and Carlson stock ATTACHES to the receiver of your 10/22 the same way as a AICS to Rem700, does not make them equal.
Please note this line in the above cited review, "The flat-bottomed AI receiver is permanently bonded to an aluminum chassis that extends from the butt-stock to front of the forend. Stock-side "skins" are then clam-shelled around the chassis to create the stock. Because of this design, the rifle is unaffected by environmental changes; bedding is not required."
Which I why I stated that AI's are the best and most durable. M40's and National Match M14's are glass and pillar bedded. This creates uniformity in the connection between the action, stock, and the bolts which attach them. It also wears and can be easily jacked up if you spill CLP or something into the stock.
Thank you for reiterating that the .338 LM is an intermediate round. I believe I made this point within my comparison.
NATO doesn't forbid match grade rounds in SASR's. Nothing is "forbidden". The only thing you can't use in them are SLAP rounds (Saboted Light Armor Penetrator). In case you don't know what "sabot" means...
Essentially, a small bullet is put in plastic and then shoot down a big barrel. It goes faster and pierces armor. The reason they can't be used is because the plastic is shed from around the real bullet and it blows back at the shooter because of the M82 muzzle brake. You can take off the muzzle brake and then fire them.
The .308 doesn't have a flatter trajectory than the .338. Sorry. Look it up.
I also stated that it was my opinion that it would be the best all around round. Not the ONLY round. There are purposes for everything. I do believe I said that as well.
