[QUOTE="bigngreen, post: 827802, member: 13632"] Thought I'd just start a new thread for the data and performance of the 6.5 SS with the 160 Matrix so the info stays better organized. I chose to concentrate on the 160 Matrix because it's really the only bullet right now that I'd confidently shoot a bull elk within the capability of my range finder which is in the 1000-1100 yards range. Rifle specs; Savage model 12 with a Benchmark 5R 1-8 twist light palma contour at 28.5 inches. Set it up with the nut and no muzzle brake, it's sitting in a punished B&C varmint stock and a Vortex HS LR optic. All shooting will be of a harris style bipod with rear bag and all Chrono numbers will come from a Magneto Speed V2. The first set of numbers I got this morning were the start of getting a load and shot from a fresh clean barrel at 200 yards just for finding my velocity and pressure range to start load development. Loaded 3 rounds of 55gr of H1000 then one each at 56,57,58 and 59 gr with a BR-2 primer. I got some slight pressure signs at 58 and 59 but not as much as bolt drag just a little bit shiny on the case head, 55gr was mild. Series 2 Shots: 7 Min 2862 Max 3030 Avg 2932 S-D 63 ES 168 Series Shot Speed 2 1 2862 ft/sec 55 gr 2 2 2885 ft/sec 55 gr 2 3 2875 ft/sec 55 gr 2 4 2925 ft/sec 56 gr 2 5 2953 ft/sec 57 gr 2 6 2995 ft/sec 58 gr 2 7 3030 ft/sec 59 gr [/QUOTE]
