1st off I would like to say hello to everyone and there seems to be a great deal of knowledge in the members here and the willingness to share it. That is great to see. I have been reading countless threads on reloading and learning tons and I thank all that have contributed. So here is a little background on me. I am an avid hunter big game, small game and upland & wetland birds and have always shot factory loads. Do to the sky rocket in ammo prices and the uncertainty in the future with the newly elected president I have decided to get into reloading. I have been shooting quite a bit more paper these days with both pistols and rifles and it just makes sense to save money and have a more accurate round. A friend of mine has been reloading for a few years and has given me some great direction and helped me set up my bench with a recently purchased RCBS reloading kit/package. I plan on 1st starting with reloading for my XD40 & XD40M. As suggested from this site as well as my friend I have gone out and bought a few books on reloading: Lyman Pistol & revolver Handbook 3rd Edition, One Book/One Caliber The complete reloading manual for the 10mm .40 S&W. I also have the Speer reloading book that was included in the reloading kit. I have a couple question I that seem to be conflicting information from my buddy to what manuals are stating. My friend was with me when I purchased the material needed to start building rounds. He is what he suggested and I purchased: Speer brass ”I trimmed to .840”, CCI 500SP primers, Speer 180GR Gold Dot HP. I also bought a 500 count bulk bag of 180gr plated bullets I picked up at the last gun show but have not attempted to load with them yet. I have AA#5 for power. I would love any other suggestions on different combos / products 1. It was suggested to me to load 5 rounds at a time with varying powder amounts. The 1st five he helped me load were below the Sugg starting grains of 8.7gr, He loaded 8.0gr. From what I have read in a couple of my manuals it is dangerous to load below the min charge? I do not want to get hurt or damage my firearm so I since dismantled these rounds to add additional powder up to the minimal 8.7gr. 2. Is there any risk of case failure / problems loading to the max call out 9.7gr? 3. My buddy informed me not to “taper crimp” crimp my rounds? He said it would cause an unsafe build up in pressure, however my manuals recommends a medium Taper crimp? I am not sure how to proceed but tend to lean a little more to what the manual states. 4. How the heck do I tamper crimp? Thanks you in advance for any help or suggestions you can give to point me in the right direction. I would like to once again apologies for the long post but thank you for your time reading it.
