Just learned something

[bronko220002]

Ive been looking for H4198 powder for a while now for my SML. I have a little left that I use for loading a few CF cartridges. I was doing some research and found out that Hodgdon makes borh H4198 and IMR4198 and uses the old H4198 formulation for both. So they are now the newer canisters are interchangeable!
CORRECTION: My information from another site was incorrect. These powders are NOT the same. I spoke directly with a Hodgdon representative this morning and got the information first hand. Continue to use the different data listed for both powders.

That's good to know. H110 and W296 are the same as well

H vrs IMR was pretty interesting for me, my 700 smokeless 1/20 twist and my Cva Scout 1/20 Twist shoot better with the H version. My Brux Omega 1/20 prefers IMR. Go figure.

That's quite possible Mike if you have an older can of the IMR. Older IMR4198 was a faster burning powder thus producing higher velocities. And too the IMR version was somewhat bulkier. The newer stuff is the same formulation as H4198 both made by Hodgdon but Hodgdon kept the name, at least for now.
Other information I've learned is that Hodgdon is going to completely eliminate the entire IMR line.
Now I used to use a lot of IMR4350 so I'm thinking is H4350 going to be comparable? I do use H4350 in my 6.5CM. Also looking at other info IMR4064 is almost identical to H335.

So this is something recent, I’ve always know the 2 to be grain for grain in smokeless application.

Where did you read this because everything I have seen has led me to them NOT being the same in my CF loadings. Close but not the same.

 

[bronko220002]

check this out direct from Hodgdon: IMR 4198 vs H4198? What's the difference? - Page 2

Again...this is misleading information. These powders are not the same.

 

[ElDiablo]

Yes, I’d be really curious to hear where that’s coming from as well.

Last I read, IMR 4198 is made in Canada at the General Dynamics Valleyfield plant. H4198 is made by ADI in Australia, (where it is known as AR2207). Certainly possible I suppose that the formula is currently the same, but unlikely.

 

[LBAhunter]

I must be the only one that doesn't use either 4198 in my sml or anything else....lol....

Yeah, when you gonna change your username to N110?!

 

[LBAhunter]

Y'all keep buying that 4198, just leave the N110 alone....lol....

 

[LBAhunter]

LBAhunterN110....lol....

 

[bronko220002]

Hmmmm......N110? Guess I'm going to have to start using that!!!!!!

 

[ElDiablo]

Hmmmm......N110? Guess I'm going to have to start using that!!!!!!

And you’re only using about half as much N110 per load so roughly half the cost of a load of 4198…..

I stopped on the way home after ordering my McGowan barrel today and ordered an 8lb jug of N110. Should be here next week. It shoots great paired with a BX 195g in a HLBS.

 

[10acres]

And I’ll wait for the news release from Hodgdon about the 4198’s being the same before I’ll jump on that wagon.

 

[LBAhunter]

Yep. Less recoil!!

 

[LBAhunter]

N110 with a lightly knurled Barnes 10mm 155gr in a HLBS with a Maine wad. You can look through the scope, line up reticle, pull trigger and a hole magically appears in the target.

 

[smokepolehall]

I have 2 cans of H4198, one i opened n started to test with. My groups were nothing to write about, best i remember 53 gr gave me a true 1 5/8" at a hundred. By the time i got to 55 gr recoil on my bad left shoulder . I said self lets go back to VV110/4759 n blue dot.

 

[LBAhunter]

Yeah, I forgot about trying Bluedot. It done ok. N110 is more versatile than Bluedot.
