So I am looking up reloading information for 200gr bullets for my 10mm since my Speer Reloading Manual #14 doesn't have anything for 200gr. I am using Accurate #7 powder (it was recommended by several people as the best powder for reloading 10mm) and have almost a full pound left. Anyhow I was comparing the reload data from Accurate's web site to my Speer reloading manual and noticed some discrepancies that have me concerned. Right now I have several hundred rounds reloaded with 180fr FMJ and 11.5gr of Accurate #7. This is the middle of what the Speer manual calls for Lower is 11.0gr and upper is 12.0gr. But the Accurate site says the lower is 9.9gr and the upper is 11.0. This puts me at .5gr over what Accurate says is the max and .5 grain below what Speer says is the max load. Which is right? I have already fired several hundred of these reloads with no problems. No excess case bulge, no splits (other than an occasional but those cases were pretty old to start with) and other than some really impressive flame from the compensator (I am shooting these reloads from a G20C) and some stiff recoil (really it's about the same as when I am shooting a Double Tap 200gr WFNGC Hardcast) My question is, which reload chart to I believe? This has me concerned as I don't want to blow my gun apart because of faulty information. I have to admit that the current set up with the 180FMJ + 11.5gr is giving me excellent accuracy but now I am getting leary of shooting them anymore. So my question(s) are this: 1. Which reload data should I follow? 2. Why? I need a logical reason why. 3. I haven't loaded any of the 200gr rounds yet, and these are the components I have to work with - Accurate #7 powder - 100 :: Midway 40200RNFP (200gr plated lead safe) bullets - Wolf Primer (cases are ready to go just need spec to load with) Is the data in the Accurate site good for reload? I am looking for mid range performance, not really looking for top end. I have some 180gr Remington hollow points that I will marry up with Starline Nickel brass, Winchester primer and AA #7 powder that I will run close to max pressure. But most of my loads are for competitive shooting, I want to run about the middle of the range since it seems to give me the best accuracy and controllability in the pistol. Thank you for your time and input on this.
