STORY AND PHOTO BY HAP ROCKETTO T here is an almost mystical relationship between smallbore ammunition and a rifle; what shoots Xs in one rifle will barely hold the ten ring in another. In smallbore, the seemingly never-ending search for “knot lot” ammunition is likened to the quest for the Holy Grail. A typical smallbore shooter will purchase a number of lots of ammunition and test them at 50 and 100 yards to find the best. Sian Griffiths, Sales & Marketing Manager at Eley, provided Shooting Sport USA, via Zanders Sporting Goods, with a supply of its new Edge cartridges for testing and evaluation. The ammunition comes in the typical Eley plastic box in a 50 round tray. The label is black with white lettering, making the packaging reminiscent of Eley Match packaging. The Eley website places this ammunition between Match and Team, but it is remarkably different in appearance than the other lines of Eley. For one, the case is black. This is a result of a proprietary surface treatment which Eley claims, “increases the frictional force between case and bullet to give a more consistent propellant burn.” 14 SSUSA JULY 2013 M AM E Y UN IT IO N ELE ED G PRODUCT FOCUS The 40-grain bullet is the flat-nosed EPS style and it is coated with a beeswax and tallow lubricant. The nominal velocity is listed at 1085 feet per second (fps), while the lot provided was 1039 fps. One should train the way one competes and this carries over into ammunition testing. The ammunition was tested over several days at 50 and 100 yards from a normal prone position, which mirrors the normal strain placed on the rifle during competition. The rifle used for this test was an 1811 Anschütz 54 action prone rifle with factory barrel mounting and a Leopold Vari-X III scope. Testing was conducted in five-shot groups at 50 yards, and ten-shot groups at 100 yards. The weather conditions were benign with bright light and negligible wind or mirage. After cleaning the rifle, several tenshot strings were fired to “season” the barrel and zero the scope. Sixteen five-shot groups at 50 yards produced an average group size, measured edge to edge, of 0.53 inches horizontally and 0.51 inches vertically. This is well within the 0.89 inch ten ring of the conventional A-23 target. The best group measured 0.54 inches by 0.55 inches, while the worst was 0.93 inches by 0.93 inches. When scored with an overlay, the average score was a 50-3X. Sixteen ten-shot strings were fired at 100 yards, producing an average edge-to-edge group of 1.56 inches horizontally and 1.44 inches vertically. Group size was well within the twoinch ten ring of the conventional A-25 target. However, even the smallest group was larger than the one inch X-ring. The best group measured 1.25 inches by 1.25 inches, while the worst was 2.00 inches by 1.75 inches. The average score per ten-shot string, using an overlay, was 100-5X. Edge ammunition does not replace Eley’s flagship—Tenex, and should not be expected to perform at that level. It is capable of shooting tens all day, but does not have the group density that will consistently produce high X counts. A former national prone champion believes that a gun and ammunition that shoots a 0.800 of an inch group consistently at 100 yards is a great combination. Taken in this light, and at about half the cost of Tenex, Edge is good ammunition which gives excellent value for the price.
