I've never really used them beyond **** and giggles. I iron sight grouped about 4" with them at 100 yards and tested them in water jugs 7 yrs ago. I should test them in gel to see if the 1800 fps gain nets us any better soft tissue performance.What are the terminal ballistics like? 100 yards, 200 yards, 300 yards? Or was this just an exercise to see how fast it can chrony at?
Beyond achieving a high FPS what is the end purpose?
That’s a damn wild looking round man.Both are .224" and I was thinking about reloading this 5.7 34gr projectile (attached picture) on a 223 case to reach very high velocities, since that would be one of the lightest 223 (and the lightest one I've seen before was like 45gr or something).
remember these bullets are LONG for weight. They will do just fine with 1:9...It really depends on your twist rate, a 1/12“ barrel would be beneficial. If you have one of the very early 1/14” barrels, better yet!
You could probably get away with the 27 gr bullets in a 1/14” twist barrels. A 1/7” is WAY too fast of twist rate for lightweight bullets.
