Testing different HP slugs of my own design for both lower powered pcp's and hp

 This pic is to show that they co go sleep quickly and give good groups at short ranges as well.

Here's the skinny.


1. Using a very thin, sharp box cutter or even thinner window decal scraper blade, press down to the very bottom of the cavity. A large, deep HP helps here a "Lot".


This will give a very wide nose. Much wider than cal.


2. Using a finely finished cone, near the shape of the original slug, press it in and tap it lightly to close the vanes. This gives a good, original shaped nose for good BC and keep accuracy the same as before the mod. Especially the poi.


3. Now size as you normally would. Finished!


For a very large expansion in hp long guns, rather than the blade, or phillips head, I use a # T-15 Torque bit with the nose perfectly flattened on a fine diamond hone. This gives very fine serrations in the hp and causes it to open in a multi petal HP. Very reliable and repeatable. Once again, I place the bit in the mill, or drill press with the depth stop set for a given hp depth.


I am making a ram with blade to fit my mill so that each cut will be precision in both depth and location. WOO-HOO!


Sadly, the card in my Sony, just went down. I can't get the old pic's out and it is full. Double GRRR!!!
I'm almost to the point of using a strong magnet to erase the darned thing if that is even possible. Update, got the card fixed! Woo-Hoo!!!

Accuracy? Can't be done? Maybe in theory no. In practice, it works just fine thank you! LOL First one to settle the reg, (Lower one) and 10 on target, 80 yards in the cross wind. Seems to work for me!

I did try one on a trash bird inthe pistol version at 470-490 fps and darned near tore it in half. Woha! There was quite an explosion. 

Here are a few pics of the pistol round to help get great expansion at such low fps. 

This is a slug sized to .2164 for the PP-700 and expanded to .454 in a 1 Gallon water jug a t 20 yards. HP's can indeed expand very well and consistently at low fps if designed or the purpose.

I did get the opportunity to shoot a 1 gal water jug at 80 yards with the heavier slug,(34 grs) at mz @ 930's and the pettes, # left of the four measured just over .60 cal. It Left he barrel at .2184 dia. 



Shot a trash bird at 20+ yards with the pp-700 pistol and it literally blew it in half. In the 50 yard water jug. test it left the PP barrel at .2163 and expanded over .450's.



Of interesting note, both MotorHeads slug and my slug test shows that the slugs actually expanded further, but continued on to curl the edges, os in reality, when passing thru the media, they actually expanded more than when they came to rest. Food for thought. This would affect any critter so shot with such projectiles. ;<)
