Ya know I really wanted the fx hybrids to work for me but I couldnt get any accuracy from them, but this is with a tj barrel. I bet those hybrids are awesome on little critters! However, for coyotes, Ive dropped more than a handful with the 65.5gr nsa at 1000fps, and not head shots. Not sure Id use the hybrids for larger game but man would they be great on pdogs! Thanks for sharing!
 
As always, great job, Chuck.

What I got out of this, is you just saved folks a lot of $$ in slug costs along with time/fuel/and Air(if they were w/o a compressor and relied on a fill shop)that we’re seeking the perfect expansion upon penetration in a slug. 

One of the reasons I haven’t dabbled into slugs was that main reason- I didn’t want to look at the end of an 8 hour shooting session at boxes and boxes of slugs that my gun doesn’t like, and each box has a $$ amount attached to it. Hence, Another reason why I’m not into trying out all kinds of different pellets. A true simpleton I am, ha!

thanks for your efforts


 
Vmaxpro, if you are getting 3/4" groups at 60 yards you are Golden! That is perfect hunting accuracy! After all your not looking for "target competition" accuracy with these hollow point bullets that were designed for hunting.

I'm glad you decided to lower your velocity...your going to have much better accuracy, especially at longer distances, if you keep them subsonic - below the speed of sound. When your pushing them at 1200 ft./s which is supersonic, there is a point where they bleed off enough energy that they begin to transition from supersonic to subsonic. That is referred to as the transonic zone, and as the bullet slows down and becomes transonic lots of weird things happen to it that just kill its accuracy at that point. One of the main reasons for this is that when supersonic the drag on the bullet is primarily on its nose...but when its subsonic most of the drag is on the base of the bullet. This transition can cause the bullet to wobble, tumble, or spiral out of control...all of which is very bad for accuracy. 

For me here by Ft. Lauderdale at Sea Level on an 85 degree day the speed of sound is 1143.8 ft./s. So how do you know what the speed of sound is where you are located? Here is a handy Speed of Sound calculator provided by the National Weather Service. You simply plug in the temperature where you are and it will do the rest for you. The chief factor affecting the speed of sound is the temperature. So here is a link to that calculator for you: https://www.weather.gov/epz/wxcalc_speedofsound

Hope you are happy with the performance of your Hybrids on small game Vmaxpro...I bet this will just anchor them on the spot! Let us know how you do on a real hunt with them please. 

All the best to ya, Chuck

Great link. Thanks a lot for some great info! Keep up the good work; some of us really appreciate it.

Nice write-up Chuck. Thank you for sharing. I must emphatically agree with the statement that shot placement is key when hunting with airguns.

The NSA ammo is good. I'm not sure that shooting them into plastic containers filled with water is a good enough test to simulate what would happen when they penetrate flesh, organs and or encounter connective tissue and bone. 

The FX slug definitely dumps all its energy quick. Maybe too quick! Would it make it through a rib cage and to the heart? That's my question. 

Chuck, I'd suggest some actually hunting tests.
 
Appreciate all the information Chuck. It seems these "Hybrid" .30 slugs (BC of 0.07) also fill a "hybrid" category between pellets and slugs. Better ballistics than .30 pellets (BC of 0.042), but significantly less than the .30 NSA (and other) slugs (BC of 0.10 and up). Would seem to be great little hunters out to 100 yards, maybe somewhat longer...
