I've got the opportunity to get a 6mm ppc boreryder reamer .Would that be a good choice for short range target shooting. Thanks .

Ask yourself, has the bore rider design ever caught on?

What is bore rider?

I'm shooting the bore rider reamer and have been for the past two or three years. Is it any better than another reamer? I have no idea. Getting ready to chamber up a new barrel or two before the Rattlesnake and Nationals. It will probably be a bore rider as no sense switching horses midstream. It seems to work best with lots of seating pressure. If you think about it, with the gradual throat that it has, it takes away the ability to change pressures with seating depth changes. So, you have to get your pressure somewhere else. More powder, tighter bushings. Very forgiving on seating depth. But, also you lose the seating depth part of the equation when making load changes. My bore rider reamer is a .265" neck. I was going to change over to a new Henriksen reamer that I have, but looked at the neck and its a .262 neck. Have lots of brass turned for .265 and loaded to fireform so will stick with the .265" neck.

The bore rider reamer amounts to being about a 1/4 degree leade instead of a 1 degree 50 or 30' leade.

Mike, to me we have two major items we can use to tune a barrel/loading, seating jam and powder charge. From what I can see from the bore rider the shooter looses the ability to adjust jam. As to neck tension which is a minor tuning element, after brass is fired a few times it gets very inconsistent as to how cases bounces back within a lot.

I may miss a great opportunity by not trying the bore rider but, hey, I have already tried short necks, long necks, 40 degree shoulders, 268, 266, 264 and 262 chamber necks and I have found out that final tuning is what makes a given barrel shoot or not shoot and the main tuning tools are bullet jam and powder charge.

Now if I could just fix my eyes. Hellsbells. I am at the point now I have to use a magnifying glass to read most text on my iPad.


You and Bev coming to the IBS next week?

No, we won't be there. Only reason I went to the IBS at Holton was because it was closer than Fairchance when they had the NBRSA Nationals and that the NBRSA Nats was going to be there the next year. Glad we went both times though as it was very enjoyable.
