I have been reloading the same Model 94 Winchester 3030 since 1958. I doubt it has had 50 rounds of factory ammo thru it in its' 50 years of existence, and it was bought new.
I load nothing but BULK Remington 150 grain bullets in it, and usually plain ole 303l Dupont. I load them to 2400fps, and call it a day. Out to about 250 yards, I'm gonna get what I shoot.
Hogs are not hard to kill. They have been here in North Central Texas for probably over a hundred years, and in East Texas for probably over 200 years, and it's fun to watch the city boys show up with their "hog guns".
You can shoot'em with what ya want, it's all personal choice but, I have shot them with a 52 grain match hollow point out of a 223, and watched them fall ON their tracks. 357 magnum in a rifle is one of my favorites, in a Model 92 Winchester. With a 158 grain jacketed soft point it will do anything a 3030 will do inside 100 yards. AND YES, I load Remington bulk bullets in it also, to about 1900 fps.
Much ado is made about the ferocity of the feral hog, but for the most part it is much like the Javalina. It does not deserve it's reputation. It mostly wants to get away. Corner a sow with little ones now, and you might get more than a fight, but a boar will usually run, unless you have dogs, and they corner him.
A 150 grain 3030 is PLENTY. JMOE
