We all walk different roads threw life, and that is OK. On some roads in life they feel that bullet expansion is absolutely necessary. And that is OK. These trekkers can never, and will never understand how a Hard Boolit with a good meplat can possibly create a predictable wound channel, that is effective at letting blood out and air in. And this is OK. We walk different roads. I know, it is OK.
Others walk a different road with hard boolitz and properly sized Meplats. They know that it doesn't have to be driven very fast or much above the speed of sound to be very effective, not overly destructive but capable of producing a good wound channel with out destroying the entire area. And that is OK. These trekkers understand that to much speed is actual detrimental to results. ( to much tissue damage and slowed flow of blood, because of the great clotting ability of the cells nucleus, if it is membrane is broken in the destruction) They realize that there is a formula for accurately predicting the wound channel size, based on Meplat size an Speed of projectile. It can be referred to as tissue spray area, DV. And that is OK. We simply travel different roads. And that is OK.
I copied and Pasted this short old Test from another forum to share what a slow boolit can and does do.
" Impact test photo This photo goes back about ten years but I only dug up yesterday.
Around the time of the test I worked for a company that did warehousing for a bakery product firm and one day I scored some 30-40lb slabs of bakery shortening that was being binned. I used it for impact tests.
The test pictured was at 50m and I compared a subsonic 311008 ex my .32-20 against a .22RF HVHP. I poured a thin plaster mix into the bullet holes to form a cavity cast.
The 32-20, even at subsonic, passed right through 15 inches of shortening and embedded itself in a fence post 100m behind the test.
Here is the .22RF test:
So in answer to the question of will a FN cast bullet at modest FPS have a decent terminal effect? YES."
