I will look at the 68 grain +p 9mm load.

I think the 68 grain will give me the 2000fps, I am seeking. I watched a video where a guy was getting 1950fps out of a Glock 19 with a 4.5" barrel. I now have a 6" barrel that will go into my Glock 34 .

If I can get 2000fps out of a 9mm, and it does well on hogs then that is a winning round.

That's getting pretty close to 5.56 SBR numbers. Would be interesting to see what the perm cavity looks like on a hog.

Which supply issues? Your concept has me looking at 357 SIG conversion barrels.

I have thought that a subgun in .30 carbine might be effective. High capacity, serious cartridge and effective out to 100m. ?

I don't think it's possible from a 9mm package. Even if you came close to that with a 9mm +P or +P+ with the light 65-68gr bullets will you get the penetration you are looking for? The velocity will be juiced up no doubt, but the physics of the weight vs length ratio (I forget what it is called) would seem to me to indicate lower-than-optimal penetration. Not sure if a FMJ template would work better or not.

If .35 caliber is key, 350 Legend might be the best combination of AR fit, power and cost. Or try 300 BO, which is designed for shorter barrels. In any case, straight blowback can only handle so much chamber pressure, unless you use something to delay the blowback, like HK roller locking.

sectional density
logic would imply that short wide projectiles destabilize quickly and penetrate more poor than long skinny ones

Finally the ammo is back in stock. I am going to be ordering a bunch of it.

Underwood say 2100 fps out of Glock 31, I am going to be going with my Glock 35 with 5.85 inch threaded barrel.

I cant wait to get this ammo out to shoot hogs with friends. If it performs as I believe it will, then the Glock 35 will get a Leupold Delta Micro installed and become my carry gun. I then will get on the waiting list for a 357 sig upper with an 8 inch barrel. This will be matted to a CMMG Glock lower. I then will have the perfect duo for carry pistol and truck gun. All mags will be the same and this should work very well out to 150 meters. I don't think as a civilian I will ever need longer than that and I put needing distance past 75 meters as like almost never in civilian situations in the USA.
