700 Modified Bolt for 6.5x284 Norma

[Riesel]

Shoot It! !

I would personally take them up on a new bolt. And then find a new Smith that has a clue. I would never charge someone for anything that remotely resembled that kind of machining. Looks to me like something went wrong during the process. I would hate to think that kind of work is normal.

I have never seen this before but I do have a .284 on a Defiance action with PTG bolt and it did have a Remington extractor. Sometimes it would eject and sometimes it wouldn't. I replaced it with a Sako style and no more problems. Thinking back some relief on the boltface may have helped. It is, however, kind of an ugly thing to do to a bolt, but I'd give it a try and see if I had an issue before calling BS on the gunsmith.

If your smith did this to insure 100% ejecting, then good for him. It may have been a suprise to you, but so would having an ejection problem.

Finally got a chance to go out and shoot this rifle. I followed the Shilen break-in per the smith's request.

After shooting 5 on an 8x11 paper, I did the shoot 3 clean, shoot 3 clean. Letting the barrel completely cool after each. HSM box of ammo, 100 yards, 37*.

I shot 3 and had 3 left. Decided to leave the barrel fowled and really take my time on the last 3 shots. Instead of just "aim and shoot."

Really looking forward to some load development now.

No issues with extraction or ejection. I know a single 3 shot group with less than 20 rounds does not make a rifle.. But it sure is promising to see where it might go for a little steel and hunting rifle.

Looks like it was shot from the backside of the target.

Huh. Not sure how to take this comment, but I can assure you it wasn't.

Not meant in a bad way, just how it looked.

Fair enough. Top left S target has a funny looking round also now that you've got me over-analyzing it.

Same here, it just looks like the edges are folded forward..
Was a backer was in place?
Looked at the targets again and see the targets were tight to the plywood behind them.
Thats why they look backwards..

There actually isn't any plywood on these backers. It's a very heavy rubber material - like a conveyor belt. I snapped pictures with my phone and didn't think I would be able to see the three holes so I also tried to get a picture with no target in place. Here is what that looks like:

I've never experienced an ejection problem with 284 based cases that this would fix, or heard of this fix. But, I'll keep this in mind on my next one. I can't help but think that there has to be a less ugly way to accomplish the same thing. if it's due to to larger od of the case hitting the bolt nose, the contact area must be tiny compared to the Dremeled area. I think a very small machined area would do the same thing. I also wonder if when truing the front of the bolt nose by just a few thou, that the problem would be alleviatedifficult anyway. Bottom line, I've never had a problem and that's an ugly fix for a problem that may or may not even exist.

I agree with the assessment. I think a better solution is a different extractor.

If it extracts fine "Don't touch it"

Completely agree with this also!

I mean that if I had to do it over, I think the best solution is to go with either a m16 or Sako extractor and NOT do something like this to the bolt face.

It's working... So I'm not about to change it... But, if for any reason it STOPS working, my solution is a new bolt with a different extractor... which is how I personally would have done it from the start.

For your and others safety, don't do the Sako.

GA Precision built my first custom rifle back in '02. A 6.5x284 on a M700 LA. If I remember that rifle correctly, they opened the front of the feed lips a touch to aid in feeding the fat case and cut a bevel on the bolt nose to clear the case body due to the rebate rim. Looked factory. Ran stock clip in extractor. Ran like a top too. Never should have sold that rifle...

Not completely off topic but, a few years back we bought rubber barn mats at the local tractor supply and cut them up for backers. After 2 matches and numerous complaints from the scoring crew, we got rid of the rubber mats. They made the bullet holes look just like the ones in your pictures. Very difficult to score accurately. We went back to Celotex.
