First fox Posted February 14, 2013 Report Share Posted February 14, 2013 Hi can any one recommend a load using h322 ,50 grain vmax for browning 223 xbolt have tried 23.5 and 24 but case seams very empty. Quote Link to comment Share on other sites More sharing options...
al4x Posted February 15, 2013 Report Share Posted February 15, 2013 With that powder according to hogdon you are top end of load so I wouldn't worry too much about case fill more on how they shoot. I've not used 322 yet in .223 but I can say they only take 26 grains of varget before you start compressing loads which is what mine runs Quote Link to comment Share on other sites More sharing options...
deershooter Posted February 15, 2013 Report Share Posted February 15, 2013 I did not like H322 for .223 i found Winchester 748 filled the case much better and shot 1/4inch groups at 100 yards I was experiencing over pressure signs with the top end loads with H322 Deershooter Quote Link to comment Share on other sites More sharing options...
coyotemaster Posted February 16, 2013 Report Share Posted February 16, 2013 748 is a great powder for .223 but it is temp sensitive, as most ball powders are if you shoot in cold temps Quote Link to comment Share on other sites More sharing options...
ian_in_the_midlands Posted February 16, 2013 Report Share Posted February 16, 2013 I was about to ask exactly that same question until I found this thread. Searching another forum, I have found that hornady gives the maximum load of 25.2 gr of H322 for the 50gr V-Max in 223. Can anyone have the hornady reload data confirm this is true? If this is correct, there is a large discrpency between the information the two companies. Quote Link to comment Share on other sites More sharing options...
First fox Posted February 16, 2013 Author Report Share Posted February 16, 2013 Made five rounds up with 24 grains and went out to try them today clover leaf at 100 yards so think I will be makeing a full batch now Quote Link to comment Share on other sites More sharing options...
ian_in_the_midlands Posted February 20, 2013 Report Share Posted February 20, 2013 (edited) Had a day at Minsterley Range yesterday working up a load. Using .223, h322, 50 grain vmax, I started at 23gr and worked up to 24gr in 0.2gr steps. Resting on a sand bag, all grouped within 3/4". As the amount of powder increased, the groups got better. Like you First Fox, I found the best was with 24gr. OAL - 2.25". I managed to put 5 shots all within a 10mm grid. Strangely, shooting the same load over a chrony showed a huge variation: 2953, 2980, 3121, 3105, 3013. Whilst measuring the speed, this group was about 1/2". Surely these measurements can not be right if I am achieving groups like that? Each load was measured, and confirmed by weighing so I do not think there is any variation in the amount of powder. Should I suspect a chrony problem? I also notice the primers are starting to flatten with 24gr. I am off to gunshop this weekend for a second opinion if I should reduce the load, but I would not want to go any hotter. How flat are your primers First fox? Are you able to measure the speed, and if so, how consistent is it? Edited February 20, 2013 by ian_in_the_midlands Quote Link to comment Share on other sites More sharing options...
First fox Posted February 20, 2013 Author Report Share Posted February 20, 2013 Hi Ian just checked primers I'n fired cases they look fine . Actualy making a full batch as we speak Quote Link to comment Share on other sites More sharing options...
ian_in_the_midlands Posted February 20, 2013 Report Share Posted February 20, 2013 There is no cratering, but they are definatly flatter at 24gr. Perhaps I am being overcautious, but if a second opinion tells me I am getting close to danger levels I will let you know. Quote Link to comment Share on other sites More sharing options...
First fox Posted February 20, 2013 Author Report Share Posted February 20, 2013 I was told buy another rooster ok to 25g but as 24 goes I am happy as like you I am weighing every round as my thrower does not seam to like the powder . But if you hear any different mates by all means please give me a shout . Quote Link to comment Share on other sites More sharing options...

Each load was measured, and confirmed by weighing so I do not think there is any variation in the amount of powder. Should I suspect a chrony problem? If you go out to 300 plus yards then its more likely you will start to see the variation show in the velocity spread you mention. But 100yds it will show very little as you have noticed. But 60fps is nothing to worry about for a sporting shooter. Quote Link to comment Share on other sites More sharing options...
ian_in_the_midlands Posted February 22, 2013 Report Share Posted February 22, 2013 It is 160 though! I would have been happier if it was only 60. When the wind stops again I will try a target at 300 yards and see what the grouping it like. Quote Link to comment Share on other sites More sharing options...

Vince Green Posted February 23, 2013 Report Share Posted February 23, 2013 (edited) Ian, I would not describe your variations as being unusually high. I have found the same many times over the years with many different loads and calibres Edited February 23, 2013 by Vince Green Quote Link to comment Share on other sites More sharing options...
ian_in_the_midlands Posted February 23, 2013 Report Share Posted February 23, 2013 (edited) There is no cratering, but they are definatly flatter at 24gr. Perhaps I am being overcautious, but if a second opinion tells me I am getting close to danger levels I will let you know. Second opinion looked at fired cased and confirmed there are no signs of overpressure. He also agreed with Vince that a variation of 160 fps is not excessive. Right then.... off to load some more now. Edited February 23, 2013 by ian_in_the_midlands Quote Link to comment Share on other sites More sharing options...
