Javelin Slugs Gen 1 vs Gen 2

[Swiggs]

Today I compared my Javelin Gen 1 30 gr slugs to the new Javelin Gen 2 30 gr slugs using my .22 Maverick Sniper which includes the upgrades of a heavy liner, heavy hammer, carbon fiber barrel cover. My settings are Dual Regs @180/150 barr and Hammer wheel at 7.

My goal was to see what improvements were made between the 2 generations of slugs and the impact on velocity and accuracy. Please note that I do not work for or have any relationship with FX or the manufacturer of the Javelin Pellets.

Here were my steps (sorry i could not correct the numbers in the list using the tools available):

1. I visually compared the 2 pellets... the Gen 2pellets have a smaller hollow point "hole" in front and look a bit taller and thinner. With a micrometer (mm) I measured Gen 1 @5.54w x 8.93h and Gen 2 @ 5.47w x 9.36h (see images)
2. 
   
3. Using a scale I compared weights of 5 pellets each generation. Both generations can be considered 30 gr but Gen 1 had an extreme weight spread of .14gr and Gen 2 had an extreme weight spread of .04gr. (see image)
4. 
5. Then using the same magazine and no change in settings of the rifle and shooting from a bench in sequence, I noted a large change in velocity with Gen 2 being 90 fps faster than Gen 1.(See images)
6. 
   
   
   
   
   
7. Shooting a target @ 25 Yards with only a 2mph wind and no sig gusts I noted that the Gen 1 grouped around 1.5 cm and Gen 2 around 1 cm if I excluded 1 flyer (improved accuracy). There was also improvement in my velocity consistency (both SD and ES) in Gen 2 (See image)
   

Summary:
My personal conclusion is that there was a significant redesign in the Javelin Pellets and Gen 2 is a significant improvement over Gen 1.
Anyone else have the same experience or do comparisons?

IMO you need to shoot more groups to rule out that flier from the Gen2.

Tested both GEN I & II on FX M3, 22 cal. Gen II not only showed improved velocities (Oehler 35P chronograph) but enhanced accuracy as well. Pleased with the product.

A question guys, have you tried the difference between javelin and zan ? wich one are the softest lead for expansion at low velocity ? Thank you !
