The resulting loads may not be safe in another, min-dimension chamber of course. I also try to identify what's different between my gun and the test data gun. If I get to the top of my ladder and am still below target velocity (meaning I've got a large chamber and/or thinner brass) then I typically break out the strain gauge to figure out what's going on and provide additional margin so I can load a little above "max". I look for pressure signs, but know they may not be there or not consistent. Then I use a chrono, make a ladder of charge weights, and work up until I hit the target velocity rather than target charge weight. My experience shows, generally speaking, the faster-burn-rate choices work better with bullets weighing up to 60 grains. Burn rates range from IMR 4198 (fastest) to CFE 223 (slowest). Personally, I use QuickLoad to get an idea of how velocity and pressure relate for a given cartridge/powder/bullet in a gun with my barrel length. Hodgdon offers more than a dozen different propellants for reloading 223/5.56 ammo. Second, different chamber dimensions equal different capacity while firing, and that makes a BIG difference in final performance and pressure. Thanks in advance for any suggestions or shared experiences.The data never matches for a few reasons. a 150 grain bullet in their 308 service rifle on line load data section. Hunting trophies or punching paper, precise rifle data is in sight ». Originally, Hodgdon H335 Smokeless Powder was used to load the militarys 5. But I always appreciate the knowledge and experience of the handloaders found here. Target shooting or just plinking, take hold of the most current handgun data ». I will start at a 10% reduction and work up and chronograph my work as is my norm. 357 with this as well.so please chime in on these as well. Have any of you had experience with this powder in 9mm? HS-6, from the Hodgdon load data site list the 9mm 130 gr plated bullet at 5.9-6.5 grs.that should be a pretty full 9mm case, if not a compressed load. (from Hodgdon's website:"HS-6 is identical to Winchester's discontinued 540".) HS-6, from what I have found online, seems to be the same powder as the older Winchester 540 fwiw. If you're unsure, or just want options, check as many boxes as you'd like. Then select your bullet weight, powder manufacturer and powder type. Select your cartridge type from the drop-down list. For the 130 gr I generally extrapolate off of data for 124 gr plated bullets and have done quite well thus far using Green Dot, Unique, AA#2, American Select and Winchester 231. Pistol SET YOUR SIGHTS ON PISTOL RELOADING DATA Find what you need in four easy steps. I simply turned the new load downrange with the aid of my Australian. I plan to load 9mm lead bullets in 147 gr and our own powder coated cast 9mm bullets that weigh right at 130 grs. Hodgdon had offered up several types of new powder for this end of my research. All the data that you know and love is still here, but now it’s easier to use and accessible on your mobile devices. (There sure is a lot of variation in burn rate charts! :shrug: ). The Hodgdon Reloading Data Center is new and improved. We do not take backorders and our Tech Services team cannot take. We place limited powder inventory for sale on a regular basis on our website. Hodgdon lists the burn rate at 42, between AA5 and Winchester Autocomp powder. We continue to prioritize our shipments to our traditional sales channels to maximize powder availability at retailers. While powder is being more readily available, I don't want to get caught up short when the next round of shortages hit.like after the upcoming Presidential election. In an effort to expand my options I picked up a pound of Hodgdon HS-6 over at Proneshooter in West Knoxville.
