[QUOTE="brianwinzor, post: 78398, member: 1067"] Lerch, About 3 months ago, I accuracy tested and chronographed Richards 130 grain BCFBHP and 142 grain ULD in my 25/06 AI, which has a Sako L61R action, and Shilen SS 24 inch 1 in 10 twist barrel. The 130 grain bullets grouped well, but the 142 grain ULD failed to stabilise and keyholed into the 100 yard target. The 130 grain BCFBHP gave good accuracy from 2850 fps through to 3150, and estimate that a standard 25/06 should reach about 2850 - 2925 fps in a 24 inch barrel. I base that prediction on the basis that the barrel on my 25/06 AI started life as a 25/06, and after 100 shots, was then set back and rechambered to the AI. The velocity increase was about 225 fps with the 100 grain bullet, which was similar increase to what I achieved with my other 25/06AI. Unfortunately I have been too busy to do further testing, but have listed below my chronograph data (forwarded to Kirby and Richard) from my only days testing of the 130 & 142 grain bullets. Remington cases, Rem 91/2 M primer, temp 20C: Case Capacity to base neck- 63.5 grns H1000,66.0 grns H870. 130 grain Wildcat Bonded Core Flat Base HP (1.215- 1.222 inches) seated about 0.00 to.007 into lands. AR 2217 (H1000) 58.0 grains - 2960 fps (1.220 moa) 59.0 grains - 2982 fps (.695 moa) 60.0 grains - 3019 fps (Max, .543 moa) 61.0 grains - 3059 fps (Above Max, 1.380 moa) Reloader 25 58.0 grains - 2978 fps (.405 moa) 59.0 grains - 3036 fps (.600 moa) 60.0 grains - 3091 fps (.465 moa) 61.0 grains - 3158 fps (Near Max/Max, .510 moa) Vihtavouri N170 58.0 grains - 2861 fps (1.171 moa) 59.0 grains - 2855 fps (.595 moa) 60.0 grains - 2925 fps (.770 moa) 61.0 grains - 2969 fps (Mild Pressure, .615 moa) Hodgdon 870 65.0 grains - 3038 fps (Max pressure. .185 moa) 66.0 grains - 3044 fps (Above Max, .645 moa) 142 grain Wildcat ULD (1.362 - 1.367 inches) seated .010 into lands. AR 2225 (H Retumbo) 59.0 grains - 2914 fps 60.0 grains - 2997 fps 61.0 grains - 3048 fps (Max) Hodgdon 870 64.0 grains - 2953 fps 65 grains - 3018 fps (Max) I hope that the above information is of some help for your 25/06 with regard to the 130 and 142 grain Wildcat bullets.
