harder than .22lr hp's, on animals. ditto much harder than .22 mag hp from a 6" revolver, too. 400-600 fps more velocity can mean a LOT, given the same diameter bullet and same bulllet wt, IF that bullet USES its energy effectively.
maybe you want to claim that we can't GET 2200 fps in ccw autopistols? it's rather easy, actually, with rds like the 357 Sig, 10mm, 9x23 Winchester. It's just a matter of a light enough bullet, with a BIG hollowbase, of the right material and size to build ENOUGH pressure in the barrel, and thus, get that much velocity. The mass producers want to make MILLIONS of $, so they refuse to use the methods that really work to achieve such velocities. With an automatic screw machine, however, hollowbasing and hollowpointing of hard-cast, solidtin bullets can be speeded up to make it feasible to sell them for $1 each,if you aint greedy.
The slow part is beating open the sprue plate on the mold. Tin is HARD, and once it cools enough to open the mold, man,it takes LOTS of serious whacks of the big rawhide mallet to shear off the sprues.
GK, you do realize that you are trying to achieve with 1970's technology what can be now be accomplished with standard, off the shelf fighting loads with modern, computer designed hollowpoints that uniformly hyper-expand, like the Rem Golden Sabre for instance.
With your loads, no matter which way you cut it, you're still beating the sh^t out of your weapon.
I'm not a reloader, I buy bulk ammunition to keep down the cost. However, I really see the advantages of reloading and have seen some remarkable shots made with tailored ammunition. That being said, 124 grain Hydra-Shoks for my 9MM's and 230 Grain Golden Sabre for my .45's is what I keep available. More than one U.S. Attorney has told me the quickest way to lose a lawsuit is a "custom" gun and "homemade" ammunition. "use what the cop's use" is good advice.
