First reloads=SUCCESS. Still some issues...
Well I got out to shoot my first 20 reloads.
Remington .223 brass 24.3 grs of H335 55gr Midway Dogtown HP Remington brass CCI 400 primer I had success! Just as accurate as factory loads shoot in my rifle, but ever 3-5 rounds I'd have one go off, make an 'off' sound and end up keyholing at the 100 yard target. They always hit close to the bullets that went straight, but why was this? I know what the sound at the shot was, it was the bullet tumbling in flight, so that question doesn't need to be answered. Just curious as to why this was happening. I was no where near the 4000fps max of the bullet, and I've shot 55gr bullets (factory loads) in my rifle before and never have had that happen. My rifle is a Stevens 200 which I believe has the 1:9 twist in it. That should still stabilize this bullet. Where am I off? Thanks in advance! Last edited by Jbotto; October 9, 2011 at 10:30 PM. |

Wow. My apologies, I'm reloading for the .223 Rem. I will edit original post.

One Question: What was the temperature?
One Suggestion: Use CCI450s (mag primers) with H335 to get dead sure/consistant ignition |

My first guess would be the el cheapo bullets.
That's where I would start anyways. Get some 53gr Hornady or Sierra match bullets and see if it goes away. If it doesn't, about the only other thing I can think of is some sort of flaw in the bore. And a question - Did you shoot any factory rounds through this rifle, and if so, did they do the same thing? |

I don't blame the CHEAP bullets, because they are Nosler made, and have heard great things about them from a bunch of different people. The temperature was about 65 F today. Also, as stated in the original post, I have shot factory ammunition through this rifle before and I've never had any bullet weight do this, from 45 grs to 68 grs.

I have loaded maybe 400 rounds now using between 24.5 and 25.0 grains of either H335/WC844 and my CCI small rifle primers have worked well in warmer temperatures. I know of no key holing in my loads. I used quite a few of the RP brass so I wouldn't need to remove primer crimps.
I use 55 grain fmj military pull bullets, which I can't imagine are any better that your Dogtown bullets. I think my DPMS has a 1:9 twist barrel also. Don't know.... Last edited by Miata Mike; October 11, 2011 at 09:58 PM. Reason: Uber typo! Sorry! |

Well you could get some better bullets and if that doesn't fix the problem, then you'll still have them when you do find your solution.

Thanks everyone for your responses. I'm just kinda pulling my hair out wondering what I did wrong. Maybe it is the bullet. I don't know. I'll just keep trying things and I'll have it figured out in no time! (hopefully)

Could shaving copper off the bullet during seating cause something like that?

Some things to check:
- concentricity after seating. If concentricity is way off, it could be off enough that it starts keyholing after. It obviously also affects accuracy - OAL after seating I use your recipe with a few different 55gr bullet profiles and don't have any issues with any of them. Good luck. |

How are you reloading? Progressive or turret press? Single stage? Have you checked your powder measure and scale for consistency? I have had a very BAD experience with a low end powder measure and got low and light loads. P.S. Usually I'd look at the bullets, like everyone else is suggesting, but given your description I'm inclined to start looking at all of the components and the process that you are using. Are all of the components new? Just thinking out loud here...

I'm using a Bonanza Co-Ax press, Lee Collet dies, and all new components. I forget what scale I have, but I believe it's a Lyman beam scale. I'll check tonight. I've just been weighing each charge and using a RCBS trickler to finish it off to the measure. The loads felt normal to me. They were no quieter or louder and I know that for a fact as I shot my normal factor loads just before I tested the reloads.

I was shooting at a scrap piece of sheet metal yesterday with my M&P Sport and noticed some keyholing as well. 24gr RX15 and 55gr FMJ. Weird. I guess those things couldn't wait to start tumbling!

jglsprings: I see where you are coming from. The report of the rifle was the same as always, but the odd sound I heard was the bullet tumbling in flight. My apologies for not being clear. It sure makes a strange sound though!
