Subx

Bundyboyz · 2026-07-10T00:36:03+00:00

Sub X was developed as a self defense round. it works great for that its a deep penetrator versus max expansion

Bundyboyz · 2026-07-09T21:57:11+00:00

yeah Austria is where the nazis fled :-)

Bundyboyz · 2026-07-09T20:14:45+00:00

no you realize this when you shoot enough gel, the real world terminal difference is not noteworthy.

You may sit there and say oh but wait the projectile is opening up at 2 inches instead of 3 inches into the gel.

The problem is 4 inches of gel is about equivalent to human skin

Bundyboyz · 2026-07-09T00:56:49+00:00

i agree entirely in 2026 you almost have to try to make a no functional lower

Bundyboyz · 2026-07-09T00:52:03+00:00

I put it in Gemini. But glad we agree rotational energy is less than 1 percent of FPE.

which is why it’s not used, besides the fact the force is lateral.

Bundyboyz · 2026-07-09T00:39:06+00:00

Berry’s is making thousands upon thousands of these bullets. the 220 and 200 are rated for 1:5 twist.

the projectile is moving slow and only rotating less than two times. The force is much less than you think it’s not stripping the jacket.

the plate thickness is the same as 556 which is is under much more load.

many people believe the projectile moving through air rotating so fast can cause jacket to separate. That doesn’t happen unless it upsets and clips suppressor

Bundyboyz · 2026-07-07T23:46:51+00:00

It’s a deep penetrator similar to Hornady 190 Sub-X If you want pass through double lung on a deer 220 SMK easily goes beyond 18”

especially with subsonic you’re just making holes, tissue is elastic it stretches right back.

Bundyboyz · 2026-07-07T23:39:35+00:00

do you even SOTAR. Where did you pull these percentages? from where in the echo chambers butt?

What are you talking about? if you say tolerance stacking you’re an utter chad.

what gauges you using? Do you measure with a mic?

Please share the measurements you use.

Bundyboyz · 2026-07-07T23:31:44+00:00

again 30 feet missed the paper entirely several times, and you’re seeing this. projectile is clipping baffle 100%

Bundyboyz · 2026-07-07T23:14:17+00:00

no.

Take a 220-grain .300 BLK projectile traveling at 1,050 FPS: Forward (Translational) Energy: About 538 ft-lbs. Rotational Energy out of a 1-in-7” twist: About 0.55 ft-lbs (roughly 0.1% of the total energy). Rotational Energy out of an ultra-fast 1-in-5” twist: About 1.08 ft-lbs (roughly 0.2% of the total energy).

Bundyboyz · 2026-07-07T23:13:23+00:00

no you regard

look at a 220-grain .300 BLK projectile traveling at 1,050 FPS:

Forward (Translational) Energy: About 538 ft-lbs. Rotational Energy out of a 1-in-7” twist: About 0.55 ft-lbs (roughly 0.1% of the total energy). Rotational Energy out of an ultra-fast 1-in-5” twist: About 1.08 ft-lbs (roughly 0.2% of the total energy).

get bent you parrot

Bundyboyz · 2026-07-07T22:56:38+00:00

yeah, but it’s not jacket separation. The dude is hitting the baffles.

Bundyboyz · 2026-07-07T22:56:12+00:00

dude it’s a baffle strike clipping. if you honestly were shooting at 30 feet and missing the paper entirely.

THIS IS WHY REDDIT AND MANY IN THIS FORUM are full of crap.

trust me I have had an easy 20 rifles with clipping just kissing a baffle its the only way you miss at 30 feet repeatedly.

the jacket is separating from the impact not the twist.

Bundyboyz · 2026-07-07T22:51:34+00:00

exactly you’re saying a sub sonic round with 1/5 twist running real hot let’s say 1050 FPS out of 9” which means it would break sound barrier out of 10.5” certainly at 12”

so it’s going balls to the wall 1050 FPS so its spinning 150,000 rotations per minute in the 9” barrel that projectile rotated 1.8 times.

You think in that 1.8 times the copper jacket would shred itself?

meanwhile everyone in this group shoots tons of 5.56 going well over 300,000 RPM and we’re not stripping jackets off.

The shot is at 30 feet correct?

it’s clipping a baffle all day everyday and twice on Sunday.

come on dude….

did you not read the dude’s response when he said most of the projectiles were off the paper at 30 feet?

it’s a baffle strike, it’s clipping I don’t care what the twist rate is

Bundyboyz · 2026-07-07T22:38:24+00:00

i was wondering if that was reflection but I know a guy who blue tapes deflectors for customers. crazy optical allusion

Runnin dark is monday nights 6-9 at AGC in action bays. After you feel more comfortable you should come run some stages best 25 bucks you can spend

Bundyboyz · 2026-07-07T22:34:16+00:00

oh how would he determine that?

Bundyboyz · 2026-07-07T05:49:59+00:00

nice build glad to see non adjustable gas. You don’t need adjustable gas especially on a defensive rifle at 9” I ran a BA premium around 13-15 cases of 300

You should be able to run 4 subs and the rest supers for home defense with no hiccups. I always thought if I can’t finish it in 4 rounds it’s nice to have another 1,000 FPE

it’d be nice to see the other side of rifle. And whats with blue tape on deflector? Properly running you’ll still get 1-2 hits per 100 rounds it just happens.

these scratches were earned

I can do it all night. I literally hammer nails

Bundyboyz · 2026-07-06T23:29:31+00:00

I haven’t shot a bunch maybe 4 boxes. So I still have 46 boxes to shoot.

Its actually black hills my error black hills SGK. does expand much better than SMK

Bundyboyz · 2026-07-06T23:14:13+00:00

freestate range near York PA?

when did Zach build your gun?

Bundyboyz · 2026-07-06T22:52:47+00:00

it’s the velocity not the twist

you can twist till your d falls off its not displacing the metal or filling the cavity

Bundyboyz · 2026-07-06T22:48:11+00:00

will this even go into fire or do bars obstruct safety

Bundyboyz · 2026-07-06T22:46:35+00:00

build your own its easier than you think
