I have a winchester model 94 made in 1898. I inherited from my grandfather. I shot a couple boxes of factory ammo through it with no problems, I got some hand loads from a very reputable loader. However they don't seem to want to fire. If I pull the hammer back and shoot again 2-3 times they eventually fire. After the first try I have checked the primer and there is a dimple from the firing pin. I been to broke to buy more factory ammo to try. Could it be the ammo or is it the gun? Any advice or info would be greatly appreciated.
