Loading with H110 or 296

[Hanshi]

Both 296 and H110 are my powders of choice in .44 mag hunting loads. Accuracy and power are splendid with bullets from 200 grain HP to 240 grain HP.

In my experience, however, they really shine in the .22 Hornet giving sub moa accuracy and factory or better velocities.

Yes, they do flash mightily in revolvers.

I'm not absolutely sure that those who have not been sucessful in nearly completely eliminating the flames are using magnum pirmers. I know the Winchester primers are stated to be effective for both standard and magnum applications. However, though they are in most cases sufficient to properely ignite 2400 and other powders that are on the slow side for burn rate, they still don't have the necessary ignition properties necessary to light H110 or 296 up efficiently. This is often a cause of the flames and even higher pressures with those two ball powders.
I've finally found the sweet spot which is up at the maximum end of the data listd and just wanted to pass on to those who enjoy the best of the wheel gun magnum powders currently available.

Even tho this is not my thread,thanks,gamestalker. I always use CCI 550 primers and I,too,am loading right up at the max with 180gr XTPs (357) with no signs of overloading. 13.5gr. My 6" GP100 handles them well. I like the powder and it has an added built-in safety net...impossible to accidentally double-charge

Who says pressures continue to rise after the bullet has left the barrel? That to me, seems an impossibility.

And what's wrong with the flames coming out of barrels shot with a charge of H110/296? That is burning gasses resulting from ignited powder under pressure. Seems perfectly normal to me. And why try to subdue it? It's the nature of the beast.

Who says pressures continue to rise after the bullet has left the barrel?

I can imagine that. If the gas is being generated faster than it can get out the pressure will be rising. Think of the pressure generated by a blank with no bullet at all.

I would like to know if muzzle flash is only present when unburned powder remains in the case/barrel after the bullet is gone.

The hot gasses that leave the barrel behind the bullet can be glowing with our without unburnt powder. They glow simply because they're hot. Just like the filament in an incandescent light bulb.

 

[bluetopper]

When the bullet leaves the barrel, tremendous pressure is released very suddenly........that's what makes the "boom". Pressure does not continue to elevate under any circumstances.

gamestalker,

i'm not sure why you want to eliminate the flame from h110, but i'm glad you finally worked up your load. i have used cci magnum primers in my h110/296 loads for quite a while and have had no issues.

a very healthy crimp on all h110/296 loads helps powder combustion and keeps bullets from walking out of the case under heavy recoil. i don't use any other powder in my heavy 44mag and 45lc loads.

Having loaded WW296 for many years the rule from Winchester was that the powder MUST occupy a minimum of 80% of case capacity with the bullet loaded in the case. It has always been a powder that likes to be lightly to heavily compressed for most loadings.
Much of the powder is burned outside the gun and not in the barrel which is why you get the big flame. I run the 24 grs. behind my 240 gr hardcast swc bullets with very good results.

I have went to using the Ramshot Enforcer powder in my 44magnum & my NEF Handi Rifle in 500 S&W Mag The Enforcer does great and gives excellent velocites & pressures I switched from the H110 to the Enforcer & its doing great

Through the years, has there ever been more threads about a particular powder on THR than H110/296?

If there has, I don't know about it.

WW-231 and HP-38, same powder, lots of discussion about it. Same goes for WW-540 and HS-6, same powder lots of discussion. Again, WW-571 and HS-7 same controversy.

This one I'm not sure of, but I've "HEARD" WW-748 and H-335. Also WW-760 and BLC-2 are the same. Notice they're ALL Hodgdon and winchester powders. Hodgdon has NEVER made powder. It simply bought huge lots of bulk powder from winchester-Olin, then re packaged it with their own labels and load data.

Hey there Murf.
I'm not trying to eliminate the flames from 296/H110 but was only stating something I read from a reputable reloading source, and for the life of me I can't remember which one. I thought it was in my Speer manual, but I read cover to cover, again, and couldn't find that specific claim. I had hoped someone else might have read this and could identify the source.

Snuffy I "heard" the same about WW-748 and H-335 but 748 has a flash suppresant added.
