We quite often get asked to make stocks to a certain weight. In some cases to make up weight to be on the max weight limit for a competition rifle. Some rifles are for hunting rifle matches in Germany. Say our base hunting stock in carbon fibre would weigh 700 grams (24-25 oz) and the weight would be ordered at 1800 grams, we would add lead while laying up the stock. The carbon and resin of the stock would be the same as an ultra light stock at~700gram but we would add and distribute ~1100grams of lead between the sides of the barrel channel (~20%) and the top of the comb (80%). In other words as close as possible to the line of recoil. With our tactical stock we offer to make the adjustable cheek extra heavy or to an ordered weight which can be between 75 grams and 700 grams..... or make two, 75 grams for hunting and 700grams for the range.
I am convinced a rifle shoots best when the centre of gravity is on the line of the bore. If one adds weight, add it in such a way that the centre of gravity gets closer to the bore.
