2020年6月17日 · I have consulted several load manuals for 357 mag loads using 158gr Berry's plated RN using Unique. I saw that Lyman 49 and 50 have a load using unique starting from 6.4 to 8.3gr. I loaded up some test loads about 20 of them that is using 7.5gr of unique to a …

2016年6月8日 · My favorite loading of all calibers with Unique: 357 Mag with a 125gn JHP bullet. It seems to perform well with 125's. I've ran this load up to 9.6 grains (Speer #14 max), but settled on 9.2 grains.

2019年12月5日 · My advice for the OP is if you have Unique and want to use it in 357 mag casings, think of it more as a 38 +P powder in a magnum casing, rather than as a full charge 357 mag powder. So while I would use 6 grains of Unique behind a 158gr LSWC for about 1000 fps, I wouldn't consider Unique as a candidate for more speed with that bullet in a 357 mag.

2016年10月26日 · I've searched but not found much recent data on mid-level load data for .357 mag loads. I'd think the burn rate of Unique would be about perfect for 1000-1100 fps or so with 158g to 173g boolits. Even my Lyman cast Load manual doesn't have any load data?

2012年6月29日 · Unique is a good powder for light/medium loads but you want something that burns slower to build pressure more gradually for magnum loads. I use 2400 with fantastic results. My favorite .357 load is 14gr of 2400 under a Zero 158gr JHP.

2016年6月18日 · I've been able to get out and plink with my 357 loads and test some lite and mid-range loads in HP-38 and unique. Here is my report and thoughts. My goal is too have a mid-range and lite load for plinking to compliment a heavier sporting/hunt load in my 10" contender.

2006年11月25日 · Unique is a good powder for light or midrange loads in magnum revolvers. I use it in my 44 Mag with 240gr SWC for my target load. If you want magnum loads, use 2400, H110, or 296.

2019年1月4日 · We gathered up propellants, bullets, and primers suitable for handloading the .357 Magnum cartridge. The editor recently pointed out that my columns have been heavily biased toward loading rifle ammo. Taking the hint, I offered to remedy the deficiency by putting together some handloads for the ever-popular .357 Magnum.

2020年1月24日 · Unique has been used in the .357 magnum for a very long time. However, the case capacity of the .357 mag is 25.6 grains (H2O) therefore, a load of 6 grains is very low loading density (about 23 or 24 percent).

2013年4月2日 · You can do well with medium velocity loads and you might be okay in working up a 125 gr. JHP to about 1200 FPS, but when you start pushing Unique hard in .357 Magnum, accuracy will deteriorate quickly.
