SDStack

Thanks for the help guys. It doesn't matter what you say. My wife says that she is not going to do it. If anyone is interested, I found this site with some information on it. The studies are not concrete but they do make a lot of sense. I don't think it is a good idea after reading it. As the article says... Pregnancy is only temporary. http://blackwaterlodge.com/btw/articles/pr...lepregnant.html url

My wife just found out she is pregnant. Would the gunfire harm the unborn baby? We love to shoot together and now she has told me that she would not shoot for 9 months. That kind of adds a sadness to such a joyful occasion. Any thoughts?

Quote: from George D on 5:44 pm on Nov. 27, 2002 SDStack, I would be very interested to hear Brian's procedure for deducing accurate loads for pistols. (Edited by George D at 10:47 am on Nov. 28, 2002) So would I! I am so confused now I don't know what to do. Do I need a chrono or not for my purposes? If so, why?

I've been studying. Tell me if I have got it figured out. I now have an understanding of SD as it pertains to bullet weights and velocities. Let's assume I have a chronograph because I am going to order one from benos this week. If I wanted to get really technical, I could weigh a group of bullets and calculate the SD for the group and then weigh others to pick out the ones that were within +/-1 SD from the group. With or without the first step, I would pick a powder or two and weigh out 10 or so rounds using 5 or so charge weights. I would then chrono these 5 groups of ten and calculate my SD for each group. The lowest SD would conceivably be my most accurate load. Is that right? By doing this, I should have the most accurate load and could assume that they would group the best if I were to put them through the "Ransom Rest Test." I do not want to have to RR test them due to the added expense. How's that?

I have on hand: W 231 Accurate #5 Tightgroup Winchester primers 200gr LSWC 230gr LRN 230gr RN Plated (Rainier)

I told you I read too much. THe link I told you about earlier where I read about the nodes is http://home.sprynet.com/~frfrog/loaddev.htm

Ok guys. So I need to find out what standard deviation is and how to calculate it. Shoot some loads and the one with the lowest SD will more than likely be the most accurate? That sounds like a deal to me. Saves $350.00 plus inserts for a rest and a whole lot of time. I was under the impression (I read it somewhere on the web) that each gun would do better at a certain velocities. Each gun has two or three nodes of velicities that do better than others. You can choose which node you want whether you are just plinking (use the slower node to be easier on the gun) or hunting (use the fastest load for more knockdown power) Once I found that velocity, then I could easily repeat the accuracy when changing any one of the powder, bullet, primer, case, etc. Ex: If my 1911 shot best at 850 with 230gr LRN and 5.5gr of W231 and I wanted to use Tightgroup or maybe even change to a 200gr LSWC then I could work up a load until it reached 850. I wish I could remember where I read it. If I find it I will post the article. I read WAY too much!

WoW Brian. That really gave me a mental picture to work with. Thanks alot.

Again, I do not shoot in tournaments. Just for fun but I want to become the best I can at that. With that said for the tenth time on this forum. I want to get a chronograph and BENOS is nice enough to help me out but I am not sure now if it will help me or not without a rest. Here's what I did... I loaded up 200 rounds. 20 rounds each with different powders, weights, and bullets using the same primers. I was going to shot 2, 5-round groups at a target to find out which load shot best in the 1911. I did not have a chronograph. I went strictly on group size. I was anchored on a table and rest 15 yards away, but nothing was consistent. The shots were all over the place. Even the ones that shot good groups could not be repeated. Maybe it was me, but it looked like everything was lined up perfectly when the trigger was squeezed. At 15 yards, I thought I should have more consistency. My intention was to find the load that grouped the best and the buy a chronograph to see it the best loads were consistent in velocity but they were all over the place. Even if I knew the velocity, I couldn't tell you what velocity shot the best. I was told earlier that you needed to be a master to shoot accurate from a table to check grouping. Is there a cheaper way of doing this without buying a Ransom Rest? HELP! I really do want the Chrono. I love gadgets. I will probably still buy the PACT with the timer built in. At least I can get some use out of it.

You guys have been a lot of help. It is amazing how things just seem like the "common sense" thing to do "AFTER" you hear them. I love the tear off the primer box idea. EricW I would love to have a copy of your filemaker program for MY data. Feel free to email it to me. I have a fast connection so it won't matter about its size. By the way... Where on the Internet can I find out the definitions of all the shooting lingo and as required, how to calculate it? ie: SD, ES, PF, etc. Thanks again.

I am new to reloading and relatively new to shooting. I do not shoot in any competitions. My wife and I just go out and have fun. I do however want to get the most out of my investment in guns and reloading equipment. I searched for journal and diary on this site but I did not find what I am looking for. I basically need a starting point and procedures for testing loads. In the past, I have just picked a bullet, picked a random charge based on the manual and started shooting. It turned out OK, but I don't know how to find the most accurate load for each of our guns. A diary would help if I new how to go about getting the data (aside from the obvious... charge, OAL, etc.) and what data is required. Any help on procedures and required data would be most appreciated. Also, any shareware that would assist in this?

I carry my Glock 27 everywhere. It is cold weather now and a coat is usually required. I use a Don Hume H715-M. It fits comfortably in the small of your back. The clip does not require a belt to stay put. I rarely wear a belt. It securely attaches to your pants waistband. For summer carry, I plan on purchasing and using a Galco ULTRA DEEP COVER INSIDE THE PANT HOLSTER. It does require a belt but the clip attaches way down toward the bottom of the case which allows you to tuck in your shirt. I have already requested on for Christmas.

I'm relatively new to this. Who makes S&B Brass? What makes it so bad? Sorry... Duh!
