SML POWDER

[brownisdown]

As you'all probably know by now that I have just completed building my Omega sml muzzleloader with the barrel from Mark Woodman.In my Knight mountaineer 45 sml brux barrel I use 60 grains of h4198 powder,a 200 grain sst hornaday bullet with a harvester lbs sabot and fed 209a primers.All that being said I am wondering about several other powders to try in my Omega.Stay with what I have got or try IMR 4198,RE7.or N120that is as close to what I use now.My Knight sml is a tack driver and taken deer from 15 yds out to 246 yds.Or should I use what I have in both the guns.I really want my Omega to really perform as well as the Knight or better as I understand it could.

If you have a Scheels near, you might try the VV N120. I've been using it a lot. H4198 is becoming Really Hard to Find.

 

[GM54-120]

N120, a few less grains than 4198
Re7, about 3 more grains than your 60gr 4198 load.

58gr of N120 will give you about 200fps more than 60gr of 4198 and its super clean burning.

Maybe............... depending on ............ You could look at it financially.

Just a suggestion You'll end up buying bottle after bottle, bullet after bullet. If what you have is accurate and fulfills your wants/needs, stay with it.

What kind of pressures are we talking with N120 vs 4198

Here’s a couple pressure traces to give you an idea.

62 gr H4198 195 BX/HLBS - 2614 (27.7k psi)

60 gr N120 195 BX/HLBS 2828 fps (34k psi)

I have to ask why would you use N120 over N110? I get that you lose fps but you use almost half the powder with N110 over N120.

 

[ElDiablo]

One reason I would is that you get a lot more velocity for the same pressure in this example.

35 gr N110 with 195 Bx/HLBS - 2457 fps (34k psi)



These two are vastly different powders - a guy may not be able to work up an accurate load and/or one that stays under a safe pressure limit (especially with a heavier bullet) with N110.

 

[10acres]

I was thinking why N120 for the lighter bullet. I have some N120 for heavier bullets. I guess powder availability is one reason.

Where are you getting all this data from. I keep saving them every time you post a new one.

I miss TGinPA. He tested a few loads for me to know that I was safe.

Thank you @ElDiablo

You have to be careful with N110 because of your powder chamber, if you have one. You gotta make sure it fills it up. For my gun set-up, N110 is perfect for reduced loads.

Try what you got and go from there.

Thanks again Eldiablo for posting these - going to get my Mcgowen 45 ready this weekend with Barnes 195 & N120
