I just bought my 11.5 inch barrel Bushmaster .How many yards will this gun be acurate up to ?
Link Posted: 12/1/2002 5:01:45 PM EST
my SBR 11.5 bushy shoots as well as the 14.5 and 20's out to 50 yards. at 100 i could hit a round steel plate that was 12" in diameter every time, surplus ammo. never really cared enough to put in on paper though.

Good question. On a related note, how about bullet velocity? What's the initial muzzle velocity? ...and how far out 'til you hit the magic 2700 fps?

20 out of 20 rounds in a 5.5" Shoot-N-C at 100 yards with South African 55 gr. and A1 iron sights. I would guess out to 150 yrds.

I know this seems hard to believe, but shorter barrels do not inherrantly mean compromised accuracy. A short barrel has the ability to be just as accurate as a long barrel. What makes things hard is the shorter sight radius of the iron sights. Shorter barrels do steal velocity from the rounds you are putting down range, so there will be more of a bullet drop. This will not effect the size of your groups. It will only effect where the groups are hitting your target. Of course, once the bullet drops to below sub-sonic velocities, it will start doing very strange and unpredictable things. and it is true that because the shorter barrels steal velocity, bullets will drop to below sub-sonic velocities sooner than on a longer barrel, but at this point, were talking about many many hundreds of yards out.

AR-Frank Depending on the ammo, but right around 50 yards if I remember right. Pretty much makes it a CQB weapon, which is fine if you understand its limitations.

Thanks guys I was looking for acurate rifle out to 75 yards so I`m in the ballpark.

They are fairly accurate out to 100 yards. However, if you ever need to use it for personal protection you wouldn't want to use it much past 40 yards as the velocty of most ammunition out of the 11.5" barrel will not allow the round to properly fragment.

With iron sights, I can hit out to 150-200 yd. With scope, 52gr HP Hornady handloads, 1" easy at 100. I was using a 7.5" w/suppressor and 3-9x40 scope to smack fox and grey squirrels at maybe 75-90yd with no problem. The 7.5" can do 1 1/4" with the 52gr HP handload at 100yd. Velocity should not be anybodys' real concern, shot placement is the major factor involved.

As far as self defense is concerned, agreed, shot placement is critical. However, with this particular round, velocity is also quite critical, and definately *IS* something you should be concerned with. If not, you are neglecting to take advantage of the round and its capabilities.

What is the twist on a 11.5"??
Link Posted: 12/4/2002 12:44:25 AM EST
lower velocity requires faster twist so they are only available in 1/7 and 1/9 twists.

Without velocity you are just shooting 50-62 grain 22's. They will pass right on through without fragmenting. Ask Col. Chuck Santose.
