The laminate is a perfered material for bench shooters, except the guys that want the big heavy fiberglass stocks. The varmint model offers the laminate because it handles weather changes a little better than conventional straight wood stocks. It comes with a pillar in the rear and a pillar in the front giving you the standard mountings for best accuracy out of a box. The only thing that you could do to really improve and help with temp and humidity change is to glass bed the action. From experience with my rifle, the pillars do fine and my accuracy doesn't change from 30 degrees to 90 degrees with humidity. The only thing that I have to be aware of is my loads and powder sensitivity to temperature and humidity.
The varmint model would be the ideal set up if you plan on making the really long shots. It gives you a 26" heavy barrel that will offer the rigidity needed for stabilizing the heavier bullets for that long flight through the air. It will also help to keep the velocity up which is necessary for harder hits for ranges in that caliber past 700 yards.
The Mod. 16 is going to make a great mountain gun. Glass bedding isn't necessary with the new AccuStock design. It offers a full bedding system securing the action completely leaving the barrel free floating. They have already started putting it in their tatical models, and as time progresses I would imagine they will be putting them into their varminter series. With the 24" barrel will give you better manuverability through the brush and it comes in a lighter contour barrel making lighter by about 3 1/4 lbs. This will recoil more, but you could have a smith put a muzzle break on if the recoil is to much. For about $100's more they offer a model with an adjustable muzzle break. This allows you to have the break open with shooting at the range to tame recoil, and close it when you are hunting so you don't need ear protection. (You should always use ear protection when possible even in hunting situations) If works as well as my cousins did in 338 win mag. you won't have any recoil issues when you are on the bench.
The synthetic stock will give you the durability and ruggedness necessary for all weather conditions in the field. That is why tactical models have figerglass or some variation when being fielded. This material does not expand with temperature or humidity changes like wood will do. The only bad thing about Savage synthetics is they generally need upgraded. With the new AccuStock system that may not be the case anymore. If you can afford stainless steel that would be the way to go as well. Hope this helps in the decision making process!
