Re: .30-30 with spitzer tips
If you do not have J.J. Donnelly's "Handloader's Manual of Cartridge Conversions", buy it; it's a wealth of research, cheap, at any price.
The 30-30 holds 44.5 gr of water, the .300 Savage, 46.6 gr.
The .30-30 is loaded to "safe " pressures in a '94 winchester, it's most common launch site, in most manuals; the .300 Savage, to pressures accptable to the model 99 Savage, it's platform.
Let's consider; the Sav 99 was also chambered in .308 Win, a 53,000 psi cartridge, so that must be safe(???) The 340 Savage was chambered, in late rifles, in .223 Win, also a (???) safe loading, as I have heard of no lawsuits, so now we have a pressure parameter for the rifle.
I'm not gonna lay my a** on the line, and tell you what is safe, but I will say, that in equivalent volume cases, with equivalent bores, pressure curves will be VERY similar.
Were it my rifle, anything I found under .300 Savage, would be fair game for ME to load, -10%, and work up from there, to an accurate load. If the load is accurate, bullet expansion is a non issue, since shot placement, not bullet dynamics, is what makes meat!
I've killed several tons of feral pork with a .22 rf rifle, maybe a couple of deer, the same way, with accurate rifles, and loads.
Never seen a .22 expand to .30 cal, so the advantage in caliber, and velocity, is already yours, but I feel that a 2600 fps load could be had, with a 125 gr bullet, in a bolt gun, with no strain at all. I'm shooting a Martini Cadet, in .308-20 ( .32-20, in a .308 barrel) that does over 2400 fps, and it has less than 22 gr capacity, in water. No loose primers, no smoke rings, and accurate. Play with the loads, do some looking at available powders, and shoot it; that's what it was made for!
Don't start no s**t and there won't be none, Terry
