I kinda want to try h110

[buck460XVR]

Most references claim H110/W296 needs three things for good ignition. A case that is close to being full of powder, a heavy crimp and a magnum primer. IME, while one may get by without one of the three, miss two and you will have incomplete ignition and probably a stuck bullet. In .357, because of the small volume of powder, a magnum primer is a must. As you get into the larger cases like .44 mag and .460, you will see references that do not show the use of magnum primers. I use magnum primers with H110/W296 because it is very temperature sensitive(one reason I prefer IMR4227 for hunting) and the same loads I shoot in 90 degree weather, I may shoot in -10. Magnum primers assure me that the powder will ignite even in the coldest weather I shoot.

Because of it's slow burn and the volume needed for correct pressures, IMHO, it's hard to get enough H110/W296 in a .357 case without heavy compression to be dangerous and destructive. It may result in sticky extraction and I wouldn't want to shoot 'em in my gun, but it ain't gonna blow up your gun. What blows up folk's gun when using H110/W296 is shooting another round after sticking a bullet. This is why one does not download H110/W296 below tested start loads, because of the high risk of sticking a bullet.

Yes Magnum primers.....wanna try something really good, I use Lil'gun with lower pressure and higher velocity..

As far as I'm concerned, half the fun of reloading is to see what happens when you use different powders.
That's why I have 13 different powders on hand.

This is also a case where a chronograph helps.
While certainly not necessary, a chronograph would be helpful in seeing the difference between IMR 4227 & H110/W296

I find 4227 is a lot harder to find around here than 110/296 powder.

I have found that H110 has low flash especially compared to factory loads. H110 gives good performance in 300 AAC as well so you will probably see the same in the .30 carbine.

my goto load for my model 29 is a 180 grain xtp over thirty something grains of h110. this load is very high flash; it is also very high velocity and very accurate.

this powder also works very well with "ruger only" loads in my 45 caliber blackhawk. cci 350 primers is all i have ever used.

luck,

I have a good load with IMR 4227 out of a 44mag handi rifle at 24gr with a LPP mag.

is trying H110 worth it? this will be a 100yard deer hunting gun.

Note that you will need magnum primers in addition to a pound of powder to find out. In my 44 Mag loading I am more interested in how the gun reacts. There is a clear difference among 300-MP, H110, and IMR4227.

p.s. I use mag primers with IMR4227 also. I was getting too much unburned powder.
