I have burned a freight car load of Win 296, which is supposed to be the same thing.

I have found that Federal 150's beat any primer used with 296......and I've lit ton of it with anything that will fit in a Large Pistol primer pocket.

Winchester WLP was my go to until they changed from the white box. Regular Fed LP all the way.

With that said, I do live in Texas and when it gets cold here, it's like some folks have for summer days. Never an ignition issue yet

I use plenty of H110/W296. I always use a Mag Primer, and I always give the bullets a stout crimp when using that powder.
I just loaded some 357 Mag with W296, I really wanted to use those Arg SPP that many of us recently bought on the NormaUSA deal, but I dug deep into my stash and found some CCI Mag primers and used those instead, I am getting low on them.

Yes! I cut my 200 meter revolver groups in half switching from a standard primer to the CCI 550 mag primer. Did the standard primer work? Yes but not nearly the burn consistency or accuracy with H-110 as the mag primer.

I'm using H110 in the 300BO and I use rifle primers to light it off.

What cartridge do you want to load the H110 with?

 

[johnnyjr]

223

 

[RBHarter]

It was a necessity in the 45 Colts .
450s or 41s will do the job I would imagine also the WSR as well

i'm going to assume 10-12grs are being used and say yeah SR mag primers will help.
you might be able to get away with SP mag primers though.

I’ve used 296/H110 in the .218 Bee,.30 Carbine, .300 BO, magnum revolvers and .410 shotgun- but never in .223 - but I don’t load cast bullets in my .223 rifles.

 

[fiver]

there really isn't any 110 data published for the 223, but it isn't all that hard to figure out.

I use H110/296 in heavy cast reloads in 357 Mag and 44 Mag.
I have always used magnum primers as advised.
Heavy crimp is also used.

I gotta say... PROBABLY GOOD REASON!

PLENTY of FAR BETTER powder choices.

The issue isn't just mag primers, its a poor powder choice for caliber. I see a problem here just looking for a place ta happen.

I can't tell the difference in BO loads with H110/296, 2400 or Lilgun - mag vs normal CCI primers. Hodgdon does testing with srmp for a lot of loads, maybe it gives reliability to their data. 110 in 223 sounds risky to me.

Shoot a lot of h110/296 in .44 magnum. Never have used magnum primers.
