After seeing the Impact in a local shop recently, with a price of 249.99, I decided to buy one. Loading up with several different bullets of various weights, I headed out to the range. After bore sighting, I was able to bring the shots to the center of the target fairly quickly with the Tasco World Class 1.5-4.5x I picked up at the local shop for 54.99. Bullets I tested included a 250 grain SST-ML, 300 grain SST-ML, 44 cal 240 grain XTP, 240 grain hard cast SWC, 45 cal 260 grain hard cast SWC, 300 grain Speer Gold Dot, 390 grain hard cast, and a 405 grain .458 jacketed soft point. All bullets sat in plastic sabots, green hornadys for the 44's, yellow TC's for the 45's, and orange for the .458 SP meant for the 45-70 cartridge. After several groups from each bullet using 100 grains of 777, I established that the SST's were the most accurate in this rifle, so I continued testing those two only, 300 grain first. I must also mention that even the 405 grain 45-70 bullet was still stabilized out at 200 yards, showing no signs of key-holing. The 300 grain SST shot very well averaging 2" groups from 100 yards. This was with 90 grains 777. I tested up to 130 grains, but the 90 grain load gave the best accuracy. I then proceeded to fire two shots with the 250 grain SST, which landed touching each other, slightly above the centered group I had previously fired with the 300's. After adjusting the scope for the lighter bullet, I squeezed off 5 shots. What I saw through the spotting scope had to be verified with my own eyes, so I started walking. 5 shots, all touching, measuring just under an inch CTC. The largest group measured 1.5 inches, and many groups fell under the one inch mark. I tested all powder charges with the 250 SST as well, but the sweet spot proved to be the 90 grain load I started with. -Tom
