I just seen Richards post with dupliex N110 and H322 and it got me thinking that I bought a pound a year ago to shoot but never have. The 4198 just works for me really well. I am hoping to get some trigger time with the H322 as a single and see how it goes. Just curious if anyone is using it in their 45 pacnor saboted.
Thanks

My gun will shoot 68-70 grains of the H322 using a barnes and blue ribbed sabots at around 2650. I get excellent results and have killed deer past 250 yards with it. I tried duplexing it with 10g N110 58G h322 The accuracy was about what the H322 load was but ,I was only able to shoot 1 single 3 shot group and my chrongraph was not reading so, In all fairness I have not tested the duplex load. (45 caliber).

used it a few times in my 45 SMI who panhandle now has, but I've only ever used it sabotless and it worked good as a single... i liked it. not sure your interest is in sabotless but if it were i could PM you with my notes on speeds?

I thought that 68g H322 with the 195g Barnes was going to be my go to load when I first got my 45 pacnor last year. It was shooting in the 2680 fps range with sub MOA accuracy in 60 to 70F temps. Then one morning I shot that same load in 30F temps a few weeks before the season started. I lost about 100 fps and the accuracy was not where it needed to be. I then tried H4198 @ 62-63g which gives 2700-2750 fps in temps from 60F down to the "teens"and have never looked back.

well i have been shooting 73 grains of h322 with 200 sst, w/w, gets right at 2900 fps.
with this load i have never had a problem with temperature. shoots to same point of impact at 19 degrees or 69 degrees.

If it is 3" longer, then the performance of H-322 will be considerably different. I think that load of VV-110 under H-322 (if in a 24-25" barrel) would have much better performance characteristics than H-322 as a single powder. Group size at a single sitting is not the main criteria; rather ideally, the group size of a group shot at 10 degree increments from max expected down to the coldest expected would really tell the story. The classic example of this is that with straight 2015 I can get outstanding groups in 40, 45, and 50 cal rifles, yet they will be extremely temp sensitivity. Enough 2015 if a 45 or a 40 can produce a relatively temp stable load. A few grains of a faster powder under the 2015 greatly reduces the temp sensitivity of the lower pressure 2015 loads. |

That is exactly what I was suspecting. Kind of what I experienced with mid levels of 10x in the 50. You had to be at the upper end to limit temp sensitivity. I kinda suspected the same thing with H322 in the 25" 45 without really pushing it or slapping it in the butt with N110 first. |

I tried upping the load to 70g and then 72g and in my 25" barrel the jump in speed was nil once I got above 70g. I supposed I was burning all the power that barrel was capable of burning. I have shot a duplex of N110/H322 and it shot pretty well and pretty fast. A 15/55 duplex shot right at 2900 fps. While group size at a single sitting is not a true measure of a load, the results were enough for me to determine that this load was not reliable in my barrel. SB...I get the same results with 63g H4198. Little if any drop in speed from 60g down to the teens and same POI. |
