[QUOTE="Hntbambi, post: 463437, member: 12797"] Moose1 is correct. DO NOT use 150 gr of BH209. I have gone up to 125 gr by volume of BH209 and while it shot great, the primers were taking a serious beating. The speed and recoil way were up there. Below are the speeds and you can see where the velocity delta is increasing in a fairly linear trend until the 125 gr charge, where it takes a big spike. This is showing excessive pressure and should not be used. .45 caliber Disc Elite 200 gr SST Knight Brown Sabot 56° 4257' elevation Baro Pressure 25.5 Winchester 209 Primer Blackhorn 209 Powder [CODE] Charge Shot 1 Shot 2 Shot 3 Avg Vel Velocity Delta 100 2307 2300 2305 2304 Baseline 105 2324 2321 2325 2323 19 110 2345 2350 2345 2347 23 115 2365 2369 2368 2367 21 120 2390 2395 2386 2390 23 125 2460 2460 2469 2463 73 [/CODE] [/QUOTE]
