Sharpshooter’s stocks come in
laminated wood in a variety of colors. I have to say that the stocks I’ve used from Sharpshooter Supply have been pre- inletted and outside shaped/prepped as good as any laminated stocks I’ve ever gotten from any other stockmaker — and way better than most! This may not mean much to a lot of do-it-yourselfers, but to me it really helps me keep my labor cost down for my customers. My labor costs aren’t cheap, so if I can buy a stock from a stockmaker that I don’t have to do so much work on, this just saves my customers some money … which I like. The total cost of a project using a
laminated wood stock generally costs more than using a synthetic stock be- cause of all the extra labor involved in fitting and finishing the stock. But the laminates do seem to control barrel harmonics and vibrations a little better than synthetics so many people think the extra cost is worth it. If you have the ability to do your own stock work, the initial cost of a laminated stock blank is very reasonable, so it will be a less expensive way for you to go since you won’t have to pay someone like me to do all the stock work. Another advantage I like with
laminated wood is the ability to mill the side and bottom tracking surfaces of the stock perfectly in line with the barreled action. This helps it to track better, which I believe translates into better accuracy and gives you a speed advantage when trying to “run and gun” quickly during tricky conditions. You can’t do much milling and straight- ening on synthetic stocks, so I often add a tracking plate to synthetic stocks that I can align true to the barreled action for better tracking. One modification I plan to do to
this stock soon is mill the bottom of the stock so it is on nearly the same plane as the barrel. This is legal to do in 600- and 1,000-yard benchrest, but may not be legal for other disciplines. This modification is one I have been experimenting with on stocks, espe- cially when the bottom of the fore-end is angled considerably different from the barrel. Stocks that have the bottom of the forearm angled up usually work OK with smaller cartridges, but on bigger, heavier kicking cartridges it seems like sometimes it causes vertical dispersion

in the groups. I believe that on stocks like this the fore-end has a tendency to jump off the bag more during recoil, which can hurt accuracy for some shoot- ers. Some guys get along great with it while others have had problems, so the individual shooter’s bench technique also plays a part in this. Now let me tell you how I get
these benchrest stocks tracking even better than they do already. After I have the barreled action pillar-bedded into the stock, I set it upside down in the mill with the barreled action dialed-in straight and true. Then I mill the stock where it rides the bags (the sides and bottom of the stock, front and rear) true to the barreled action. I do this all in one setup to make sure it is milled absolutely straight and true, front and rear, just like I want it. Now it will track perfectly straight and true, which I be- lieve is advantageous for accuracy and faster shooting! I use Krieger barrels about 90
percent of the time for customers’ rifles I build in my shop, so it was only natural that I use Krieger barrels for this project rifle. I really like cut-rifled barrels, which is what Krieger manufactures. Since I started to “slug” and evaluate rifle barrels from quite a few of the custom barrel makers a number of years ago, I consistently found the Krieger barrels to have about the highest “acceptance rate” of any barrel maker, so now I use them the most. I decided to fit two stainless steel
barrels to this project rifle. One is a standard 1:8" twist and the other is a gain twist barrel. The gain twist starts at 1:8.75" twist rate at the chamber and speeds up to a 1:8.3" twist at the muzzle. I am chambering both these barrels identically in 6mm Dasher with
- Stocks - Barrels - Triggers - Accessories - Magazines - Scopes - Bipods
a 0.270" neck, 30" long, and am crown- ing the muzzles with good-looking, extremely true 11 degree crowns. If a bore is dialed-in straight and true when crowning the barrel, I don’t believe the shape or degree of the crown makes any accuracy difference. But this is the crown look and shape that so many shooters prefer, so it’s one I do more often than any other on target barrels. The 6mm Dasher cartridge is based
on a 6mm BR case with the shoulder blown forward 0.100" and the shoulder angle changed to 40 degrees. The 6mm Dasher is an extremely popular and effective 600- and 1,000-yard benchrest cartridge that has won many matches and set many records. It is most popular when shooting the heavy high-BC long- range match bullets like the 95-grain to 115-grain match bullets. So far I have had my best luck in the 1:8" barrel with the 105 Berger and 105 Hornady A-Max bullets. I’ll be real interested to find out what the gain-twist barrel prefers when I start load development with that. The gain-twist rifling process has
been around for many years. Now that the machining technology has improved to the level it is today, a lot of experi- mentation is again being done to try to determine if there is an advantage to this process. One advantage some engineers think gain-twist barrels may have is the ever-changing twist rate may help dampen barrel harmonics more than a conventional constant-twist barrel. Generally, anything that can be done to dampen barrel harmonics is beneficial to accuracy. Another theorized advantage is the ever-changing twist rate keeps the bullet tight against the driving edge of the lands. Maybe so, maybe not, but that’s one of the theories. One advantage that does seem to
