BLC2 in AR15? and m193 duplicating loads?

[Ammo Junky]

Anyone used blc2 in there ar? I see Hodgdon rates it as giveing higher velocity than H335. Are there any port pressuar issues? I dont see it recomended as frequently as H335. Is the slower blc2 less accurate?
TIA

Does anyone know a load to duplicate m193 performance? I get 3150fps from Q3131A, but only 3000fps from a max charg (25.5) of h335 under 55btfmj? This is in an 20" AR15.

Thanks

My AR (Bushy) likes BLC-2 & H335. I've probably shot about 2-3 lbs of BLC-2 of it during the last 2 years & I've been very satisfied with the groups from it. I load 55 gr FMJBT bullets and 2% less than max charge.
I shoot the 100yd range but don't have a chrono so I can't say about the velocity difference between it & H335.
IMHO all AR's are different, but H335 would be my 1st choice, with BLC-2 a very close 2nd.

Come on, With all the 223 loaders on this board, nobody has duplicated or near duplicated m193 loads.

I use the same powder and bullet for my AR as Toolman -- but I shoot a Rock River. No issues

I use 25gr H335 with a 62gr pulled bullet for my AR

[Hotdog1911]

1) With a 55 FMJ, BL-C will produce more velocity with less pressure than H335 & W748.

2) W748 works better than the rest with the 68 bullet plus grain .223 loads.

3) H335 produces real consistent pressures with 50 grain or less bullets with .223 loads.

As God's personal self-appointed gift to .223 handloads, I swear by the power vested in me that all the above mentioned brews to be some of the truth, all the truth, so help me Phillp Morris.

PDSHOOTER: where did you find the 62 grain green tips?

According to TM 43-0001-27 M193 is loaded with 28.5gr of WC844 under a 56gr projectile, 2.260 OAL. This yields 3250 fps measured 15ft from muzzle and 52,000 psi chamber pressure.

H-335 is supposed to be the "civilian equivelent" of WC844. If so, then this would be a true "duplicate load".

According to the Hodgdon's web site and my Sierra manual 28.5 gr of 335 is a very hot load. they list 25.3 as max load. I'll pass on that.

Hogdon's says BLC-2 and 748 are the same thing.

Most of hodgdons ball powders are in fact winchester powders
HP38, HS6, HS7, H335, BLC2, H110 and I am sure more are win powders. Their stick powders are from down under. I dont think hodgdon makes any thing they just distubite. Thats not a knock, I use hodgdons excluslevily. There are way too many variables to loading. I symplify buy using Hodgdon powder win brass and primers and sierra bullets when I can. It is at least a place to start. I did have to go nosler for the 25-06. sierra did not make a boat tail 85 grain varmint bullet in .257. Yes I am that particular in what I want.

SWmike, Do you know if that is from a 20" bbl? I always get about 3150 from the different M193 ammo I have tried.

Just pulled a couple of Federal XM193 . Carefully contained the powder charge and they came out at 26.5 Grains.

26.5gr of h335 is about what I figured I would need to get the 3150 of my Q3131A. This is based on the mv I got from working up my 55gr / H355 loads in a 20' AR.
24.0GR 2730 @ 50F Q3131A 3130fps @ 50F
24.5GR 2800
25.0GR 2830
25.5GR 2930

I suspect that 26.5 load is the same as h335. The hodgdon guy as much as said that was the case, but said he could not "tell me to" go over book. This is not over book for the sierra bolt action .223 section, but is over what they recomed for an ar. That seems funny as the ar with a 556 chamber is normaly loaded higher than .223 ammo. I dont really care if my pratice ammo is under speed if the poi is near what the Q3131A is out to 400 or so. Sometimes I get lucky as slower loads offten hit a little higher at 100 and I can make a load that closely chases the trajectory of my main load. In my 308vs, my main load is 165sgk / 44.5 varget 2660fps. Its sighted in +2" at 100. I had some 150 core lock I wanted to use up so I came up wit a load of 43.0 H4895 at 2680 fps. A max load of varget or H4895 only gave me 2800 so it is not much power lost if I would ever get to use it on game. It hits 2.8" at 100 within an inch of the main load out to 350 where it is dead on with the game kings, Yes I checked on paper. Its 1/2moa lower at 400 and 1moa lower at 450. Beyond that I use the sierra. On a side note the 165gk and 168mk both shot about 2.5" and the 150 rem shot 3.5 for five shots and they all had the same poi. Also a side note I have found floaded bbls on bolt guns or ars are a lot more consistant in their zero from one load to the next.

Got the grenn tip AMMO, from Hy-tech ammo........

Well here it is.
20" A1 ar 15 40F

55gr bullet THESE LOADS ARE OVER MAX IN SOME BOOKS.
26.0 gr h335 3068fps
26.5gr h335 3189
Q3131A 3130
26.3gr h335 should match near perfectly Q3131A In my gun.

Blc2 was dissapointing.
27.5gr 55gr bullet 3025fps.
It may give better velocities in a long bbl but not an ar.
The report was much louder, Friends down the corn field a ways came to ask why the gun was so much louder.

I probably just reinvented the wheel, but it was interesting. I will probably stay with 25.5gr H335. Its a little easier on the gun and has a close poi with Q3131A. This gun had a thiner A1 bbl that was not floated and poi changed a lot with changing from a rest to prone. Shooting it offhand, I dont think I will be accurate enough with this gun and sights to make any difference. A good friend is just finnishing basic in the marines. He wrote they shot at 500yd. I am amazed they had a chance at that distance with standard non floated bbls?

God bless em
