Lead bullets

[TScottW99]

O.K.

Just got back from the range and can't figure this one out. I have to buy a chrony SOON!!

What I thought was going to be my deer load in my .480Ruger was a Speer Gold Dot 275 grain HP sitting on top of 32.5 grains of H110. Has been shooting well for me though it does have a heck of a bite. Approximate velocity should be at least 1600 FPS if not faster.

Today at the range with a new Pachmyr grip it was shooting way low. To cool off I pulled out some "plinking" loads I had loaded up. My first lead and/or plated lead bullets I have ever loaded. A Rainer 325 grain plated lead hollow point on top of 9.5 grains of Unique. Approximate velocity should be at least 1100 FPS.

Good news - 3/4" group at 50 yards :grin:
Weird news - It was shooting about 2 foot higher then the Gold Dot.

How the heck can that happen? The jacketed hollow point should be going at the very least 500 FPS faster and feels like a 1,000 FPS faster.

The Encore with the Gold Dot load feels like a stout .44mag in a light weight wheel gun.

The Encore with the Rainer bullet feels like a Glock 17 :lol:

No signs of leading with the Rainer either. Don't worry guys, Santa better bring me a chrony :lol:

A. You need a Chrony!

B. I have only seen differences in points of impact like that only in Big Bores. 2 foot differences at 50 yards has not been wierd at all! Especially when there is a huge difference in velocity!

Not at all unusual for the heavier bullet to print a higher point of impact.

It's from the muzzle position when the bullet exits. The heavier bullets often create greater muzzle rise at the point that they exit the barrel, and thus print higher. It's not shooting flatter, the barrel is simply pointed higher up.

First ran into this about 25 years ago with a .357 mag revolver, when I noticed the blazing fast 110 grainers were shooting much lower than the standard 158 grain loads.

Hope that helps.

BTW - congrats on a great shooting load!

Bingo!!!!!!!!! :wink:

That makes sense, but... The 325 grain lead load is a real pussycat. Maybe a couple inch muzzle rise. The 275 grain jhp load is a real blast :lol: At least 6" of muzzle rise when I touch one of those babies off.
