And he is having an issue with it not going off on the first pull of the trigger. Hes cleaned the rifle many times and it does the same thing over and over.

To me,it sounds like a nipple issue. My deercreek .45 i had used to do the same thing with the stock nipple.

I have nothing against White muzzleloaders at all, i'd like to try one out in fact. I was just hoping that someone who owns a white would possibly help him out with whats possibly causing this.

Ok this is what the guy said in that forum.
"I shoot a White Super 91 and one time in texas after hogs I forgot to do my regular preshot and my charge didn't go off just the primer."
Get it, the primer went off, the primer went off. No weak spring, no flattened nipple, likely a blocked flash hole.

Welp i guess he needs to use a fouling charge to make sure the rifle will fire then.

No matter what rifle you use if the spark can't get to the powder it just won't go off. You know that.

I use 120g loose 777 ,250g shockwave and 777 primers I swab the barrel after each shot with 50/50 mixture of windex and alcohol, this results in groups less than 1" and often a cloverleaf.The superglide shockwave has same accuracy but shoots one inch higher
