Hornady .30 cal 100 gr half jackets?


October 21, 2006, 08:01 PM
I was just given some of these 100 gr half jackets and was wondering if anyone had any experience with them? Are they accurate at all, or just a real short range varmint killer?
How about load data for an '06? Any suggestions?

They'd work great in my M1... Carbine that is.

The 100 gr half jackets were designed for the .30 caliber carbine I believe. Higher velocities and longer throats may have mixed results. Let us know what you find out.

I've had good luck with the Speer version in my W94 30-30 seem to shoot about that same as the 110 grain soft-round-nose.

That's my thing! :) Shooting 110 or 100 grain bullets from my '50 W94 30-30. :)

They can be loaded up to 2700fps but I don't do that, my thing is 2200fps just a couple hundred feet per second faster than an M1 carbine shoots 'em. :)

Well you have to wear ear plugs but other than that, it's like a 22 magnum only cheaper and more fun. ;)

Used lots of Speer 100 grain plinkers and 10 grains of Unique in a 30-30 for plinking around. Much prefer the Speer 100 gr half jackets to the Hornady 100 half jackets. The Hornaday have a sharp edge on the flat bottom and the Speers had a slightly rounded bottom - makes for easier seating.

What is a good seating depth? Top of the jacket?
That Unique load is sort of what i'm looking for. Does anyone have any data for that?
I've looked through all of my load books and can't find anything for low cost plinking rounds / rabbit killers with low powder charges.

Don't think the seating depth is critical. I seated so about a 1/16" of the jacket showed. This prevented any sharp edges, particuarly the case mouth, that might cause a hang up when chambering.

J.S.TX... my '50 W94 30-30 handles empty shells perfectly. ;)

10 grains of Unique or I guess about 10.5 grains of 800-X sounds like a job for a Little Dandy to me. ;) Might have another rotor in my future. Anyone else buy them too small on purpose and grind them out and polish the cavities?

What sort of velocity are we talking about here? :)

And yeah what HuntingNT asked. :) Where can we learn more about this, I want to give it a try for kicks. :)

My old Lyman book has data for a 110 grain jacketed bullet. Fourteen different powders. The accuracy load is 54.5 grains of IMR4895 at 3333fps, 50,800 cup. 49.0 to 54.5. Depending on the rifle, I'd be seating to the end of the jacket, but watch the minimum OAL.

to shoot in my 03A3 at all.

Some rifles will shoot them tolerably well, others won't, no matter what you try. Just a bit of jacket showing would be an ok seating depth. Be aware that if you load super light that the jackets can separate, in the bore. This is an unpleasant and unsafe situation. Use care.
