joey_safety Posted January 1, 2012 Share Posted January 1, 2012 (edited) Made it out to a friends place with a Chrony this week. Took the kids, and had a great day shooting my girls new 22 with them and using a friend's chrony to get some data points. I am pretty much just running it by yall for any input, regarding any aspect. The weapon tested is a Springfield XDM 40 S&W with a 4.5" barrel. I fired a minimum of 10 rounds for each change in powder weight. *Speers 165g .400 TMJ FN *Winchester small pistol primer *First run Starline brass *Power Pistol Powder A. 7 grains, AVG = 1079 / HIGH = 1129 / LOW = 1043 B. 7.4 grains, AVG = 1129 / HIGH = 1154 / LOW = 1111 C. 7.7 grains, AVG = 1152 / HIGH = 1184 / LOW = 1135 Summary: I could not tell a difference between the starting and finishing loads with regards to "felt, received, or perceived" recoil I also ran previous identical loads using 10 at each .1 change in weight to look for signs of pressure, but did not have a chrony at that time. None of the rounds fired previously or during these runs showed any signs of pressure with regards to outside the primer. I will get a pic up. The kids were getting restless so I finished up my testing so everyone could shoot: *Speers 180g .400 TMJ FN *CCI small pistol primer *First run Starline brass *Power Pistol Powder A. 6.2 grains, AVG = 966 / HIGH = 976 / LOW = 947 B. 6.3 grains, AVG = 983 / HIGH = 1001 / LOW = 957 C. 6.6 grains, AVG = 1014 / HIGH = 1036 / LOW = 1002 D. 7.1 grains, AVG = 1076 / HIGH = 1106 / LOW = 1063 Using the Dillon 550B purchased from Brian. How do these look to you? Where should I see the best "least felt", or snap back to target with regards to powder charge? I know my own training and understanding of the fundamentals is the place to be, but I am having a great time making bullets and want to make them right MY usage is for plinking, but I am trying to be accruately and comfortably plinking. I also want it to be easy on my 13,12, 11 and 8 yr old girls I am also loading some 45 ACP along with this 40 S&W. I haven't decided which powder to use for each. I have 1 lb. Hogdon HS-6, 8 lbs. Hodgon Titegroup, 1 lb. Alliant Bullseye, and of course the Power Pistol. Which would you prefer for each caliber? I can not stress how important this site and its users are. As always thanks!
