Is H110 and H322 a workable duplex?

[spaniel]

I have H110 and H322, which the Hodgdon website shows to be relatively close to V110 and V130, respectively. V110/V130 I've seen as a pretty quick duplex on here. Could these be used in a duplex, and where would be a good place to start and stop (min/max)? I've looked through the load data and couldn't seem to find this exact combo.

Also, any update to this historical trace data as to the max for H322 as a single load?

All of this in a .45 with 200gr bullets...goal to achieve 2700-2900 fps.

MTA: I also have AA5744 I could use in place of H110 but I did not see it on the Hodgdon burn rate chart for comparison purposes.

Thanks...

Spaniel.........Pull up the posts I did this past year (about every week since February) on the .45. I have a ton of duplex loads with those powders.

Thanks Richard, I'll look again...I saw the V110/V130 loads but not the others. I'll blame it on the lack of sleep from the new infant.

10gr N110/49.5gr H322
Just under 2700fps in a 26" barrel with the 195BX.

A 10/55 ratio timed in the mid 2700's, 12/53 was 2800+. The 65gr duplex did not shoot as well for me.

Richard is right he does have a ton of duplex loads.I am thinking the N110-15grs/N130-57 grs was the fast one but check it out to make sure.I got 3000 plus with my 25 in barrel.
I think I got this duplex from him,shot it the first day I shot the 45 cal. N110-15/H322-55grs.I plan on trying this load some more myself this year.
Have shot up to 69 grs of the H322 as single load and 200 gr bullet.

[spaniel]

So you're using 69gr H322 as a single load....the duplexes in Richard's post add up to 72-73 gr. Would 72gr H322 be too stiff (the sabot may tell me!).

I'm thinking maybe start with 12/58 AA5574/H322 and working up to 15/55. Then run the same series with h110 instead of AA5574, and H322 as a single up to 70gr and see what shoots best. I'm not sure I'll feel the need to push above 70gr total charge if I get accuracy over 2800 fps.

Herman or Richard...do either of you recall the speed of that 15/55 N110/H322 duplex?

[shoot2reload]

I always thought H110 was a powder to avoid because it's small and spherical? In other applications (ie. metallic loading) it tends to be hard to ignite, so it's difficult to imagine it being a good duplex starter.

[smokeeter]

might be some confusion between H110 and N110

He is right, H110 is a small spherical powder that might seep through the vent to the primer if vent size is not monitored.

Glad someone was paying attention-I wasn't. Good catch.

Dave this is what I got in my notes:
15/55 N110/H322

2868
2883
2880 = avg 2877
I am sure richard will reply and you can compare our speeds I have a heck of a time with chronys.

This is why I don't feel bad asking simplistic questions on here. I really appreciate this catch! I knew not to use Lil Gun but did not know H110 was also on that list. I'll stick to the AA5744 until I luck upon some V110. it seems really tough to find the V powders in stock around here and I have no need to buy enough to justify a hazmat.

I agree spaniel, vv is hard to get around my area too. I heard they don't like to sell to distributers. Most gunshops have to purchase a min. order of so many jugs to become a dealer. This is what I was told but don't know if it is true.

[sw]

All the H-110 particles are small, but just the dregs of the Ltl Gun can get thru, ie bottom of container can get you in trouble. Also, ltl Gn 's pressures can get right up there.
With 5744 or 4759 I'd go appx 10-20% higher than the VV-110 load to get equivalent velocities. 5744 will wear your ventliner faster. I think VV-110 is better than the other 2 powders for a primer powder.

[spaniel]

I'll keep looking for VV-110, but given that I have a pound of 5744 I think I'll start with it as my booster and see how it goes.

[Richard]

Spaniel...........Here are a few loads I dug up:
5744/H-322
15/55........2679 fps
14/56........2650
15/56........2673
17/55.........2657
17/56.........2740

N-110/N-130
17/55........2974
16/56........2918
Note how the above two loads are both 72 gr. total weight but the one with more booster and less main charge gave the higher velocity. Not all of these loads were shot on the same day so some variance can be attributed to temperatures and humidity etc.

Thanks! This is great information to start with. I'm assuming the "N" powders you list are the Vihvourti (sp?) powders?

[Richard]

Correct on the "N" relating to Vihta Vuori!

When I first joined this board, I was informed in no uncertain terms, to NEVER use Hodgdon H-110 in the smokeless ML. I was also cautioned to be careful about confusing the 2 110s. The VV N-110 is the one to use. As far as I know, that has not been revised.
