Bushmaster .223 With 6.5-20x50mm Burris

I’m really upset about how my Bushmaster is shooting right now. I took it to the gun club on Wednesday to sight in my rifle now that it’s back from Bushmaster with the new trigger and scope combination. Short story is that it shot like crap.

Now, I don’t know if it’s the scope, the ammunition, the new trigger job or that maybe they screwed up when they polished my loading ramp when the company was fixing my jamming problem, but I used to be able to put 5-10 rounds in a 1/2 to 3/4 inch group at a 100 yards, but when I shot it on Wednesday, the groups were coming in at like 2-4 inches. (I almost threw up and cried… I’m a big baby when my pet guns get old and shaky and can’t shoot the eye out of a squirrel at a 100 yards anymore.)

I talked to the Verminator about it, and since he is way more into guns than I am, he said he would take it down and see if it was me or if it was the gun. After running the ammo I was using, which was Federal’s Power-Shok shooting a 50 Grain Jacketed Hollow Point, through the Chronograph, he concluded that it might just be the ammunition. Here are the 10 shots recorded out of my Bushmaster’s 20′ V-Match H-BAR.

  1. 3201
  2. 3215
  3. 3224
  4. 3229
  5. 3276
  6. 3256
  7. 3235
  8. 3231
  9. 3263
  10. 3228

According to the Verminator, if you take the high number and subtract the lowest number, it gives you some kind of spread or deviation that tells you something about the consistency and quality of the ammunition. So, if you take the high of 3276 and subtract the low number, which is 3201, you get a deviation of 75.

 3276
-3201
_____
= 75

The Veriminator says that the lower the number, the better the consistency and potential accuracy of the ammunition. He also said that the number needed to be under 20 to be any good and that what you really want is for your ammo to come in with a spread that is less than 10.

Now that we know that the ammunition might be the problem, I’m going to have to go to Bi-Mart and pick up 4 or 5 different types of ammunition and see which shoots the best in my rifle. I’m nor really looking forward to that, because the Federal Power-Shok is really cheap and worked really well in my rifle this year. If I have to change ammunition, I’m probably going to either spend a fortune for a higher grade ammo, or have to take the time out of my busy life and start reloading my own .223′s again. I’ll keep you posted.
