Date: Monday, May 30th, 2011 Location: SW Missouri, Table Rock Lake, our little corner of Mark Twain National Forest Weather: Sunny, 81F, Heat Index 86F, Humidity 50%, Pressure 30.09, Altitude ~500ft, Time: 10:00am Chronograph: Shooting Chrony Beta Pistol: Fusion Traditional Hunter 1911, ramped 6" barrel, 10mm While visiting family over this past Memorial weekend, I got a chance to run several loads over my chrono as part of my ongoing load workups to find the perfect whitetail, general field, target and defense loads. I tested a variety of handloads, reloads, bullet styles and powder types, as well as a few factory loads. Chrono setup My home workbench My hunting-load factory My woods "work bench" Below are the results of my chrono tests. I actually skipped a couple of the loads since they were so close to a similar load already on the sheet, or simply due to time. The format of the data is: Weight/Bullet, Charge/Powder, Lowest Velocity, Highest Velocity, Average Velocity, Extreme Spread, Standard Deviation, Comments All tests are from five-shot strings. Bullets: Hornady XTP, Remington Golden Saber (GS), Speer Gold Dot (GD), Suter's Lead Semi-Wadcutter (LSWC), Berry's plated hollowpoint, (Buffalo Bore Factory) Hardcast (HC), Winchester (SXT) Supreme Expansion Talon, (Doubletap's factory) Wide Flat Nosed (with Gas Check) WFNGC Powders: Power Pistol, Accurate Arms #7, IMR-800X 155 XTP - 9.2 PP - n/a 155 XTP - 10.0 PP - 1338, 1375, 1353, :7.24, 15.29 - nice coyote / armadillo / varmint load 165 GS - 8.5 PP - 1209, 1239, 1219, 29.97, 14.17 - nice defense load 165 GD - 11.6gr AA7 - 1252, 1310, 1292, 57.80, 23.02 - my chosen defense load - slightly exceeds the .40SW ver / ~98% one shot-stops? 175 LSWC - 6.9 PP - 1089, 1247, 1171, 158, 72.69 - nice target load, albeit takes a while to clean up, even at 1100fps 175 STHP - Winchester - 1166, 1199, 1188, ES 33.19, - again, I'm not impressed with the Silvertip's boxflap vs. actual velocity 180 Berry HP - 10.1 AA7 - n/a - i'm not that crazy about Berry's for accuracy, but they are cheap and clean 180 XTP - 10.9 AA7 - 1219, 1247, 1238, 28.41, 13.19 - first warmish 10mm handload I ever made, extremely accurate and pretty hard-kicking 180 XTP - 8.5 PP - n/a 180 XTP - 8.6 PP - 1193, 1239, 1214, 46.06, 14.52 - my chosen field load, near or under book max so I can use in multple-fired cases but still warm 180 XTP - 9.0 800X - 1281, 1311, 1294, 30.11, 10.81 - nice load, however, 10.0gr load is better since I'm hand-weighing anyways 180 XTP - 10.0 800X - 1355, 1392, 1379, 36.32, 14.03 - AWESOME load, feels very snappy, can "feel" the power, I'd bet its a deer SLAYER, will play with some more 220 HC - Buffalo Bore - 1151, 1182, 1165, 31.18, 11.09 - typical BB ammo, accurate and powerful, bit of smoke, too 180 SXT Bonded - 9.3 800X - 1358, 1393, 1373, 35.67, 17.88 - FAST! wow! need to download this per results of water jug test 200 XTP - 7.4 PP - 1049, 1103, 1079, 54.28, 22.38 - not much to say, slower 200gr loading 200 XTP - 9.3 800X - 1263, 1285, 1275, 22.67, 8.1 - my CURRENT deer load, although I will probably increase charges slightly... we'll see 200 XTP - DoubleTap - 1107, 1175, 1146, 68.42, 27.96 - not impressed regarding actual vs boxflap, however, it HAS done its job on two different deer so it does work 200 WFN - DoubleTap - 1196, 1216, 1206, 20.09, 9.11 - good solid load, not as good as mine, though 200 WFN - 7.4 PP - 1089, 1105, 1098, 16.03, 6.78 - not too much to say here, either, but would work in a pinch 200 WFN - 9.0 800X - 1218, 1262, 1251, 44.61, 22 - work up part 1 200 WFN - 9.4 800X - 1292, 1334, 1310, 41.61, 21.77 - work up part 2 200 WFN - 9.7 800X - 1341, 1381, 1359, 39.5, 18.54 - work up part 3, awesome load * NO PRESSURE SIGNS ON ANY OF THESE LOADS... except that the WFN handloads at bottom, primers are VERY slightly starting to flatten. DT load (not sure which one) had a SLIGHT increase in diameter above case web but not a bulge or smile. No bulges or splits at all on my handloads or reloads. ** DISCLAIMER: PLEASE DO NOT ASSUME ANY OF THESE LOADS ARE SAFE IN YOUR PISTOL. PLEASE USE PUBLISHED DATA AND DO YOUR OWN WORKUPS, CHECKING FOR PRESSURE SIGNS ALONG THE WAY. I was pretty disappointed in the DoubleTap Velocities, honestly. Keep in mind, these were from a 6" barrel and were almost exactly 100fps slow on BOTH the 200gr XTP AND the 200gr WFNGC load. My own 200gr loadings outclass the DT in ALL regards and i'm not even done working those loads up. Plus, I only pay a fraction of what DT charges. (Don't get me wrong, I like DT, their products, their service and all they've done for the 10mm industry... but my handloading will surpass their loadings) I also did a couple water jug tests, one on a 200gr XTP and another on a 180gr bonded SXT, both of which were handloads. The SXT bullet was actually one I pulled from a .40SW factory defense load and loaded into a 10mm case with a bunch of 800X under it. CONTD.... Wanna kill these ads? We can help!
