    bore riders

    http://www.accuratemolds.com/img/bul.../37-286C-D.png I am going to be getting this boolit when I get my rifle, my question is how much, if any do you want the bore riding section to engrave into the rifling? if the bore was .356 and the bore riding section was .357, would it be hard to chamber? thanks a lot guys!-Travis

    when I get my rifle, my question is how much,
    Purpose of a bore riding bullet is to center the bullet nose to the axis of the bore.
    With several bore rider bullets I cast, I chamber them so the leading bore cuts engrave the ogive slightly and a slight thumb pressure is needed to chamber the reload. In all honesty, I have never measured the distance - it is based on the feel chambering and capability to easily extract the loaded round. When you find the distance that your rifle likes - make a COAL dummy of the reload
    Regards

    It would depend on the dimensions of the chamber and how the riffling starts. A chamber cast would answer that. Worst it will affect is having to seat the bullets deep

    I plan on doing the chamber cast, it is what I do with that info that I was asking about, so you are saying if the bore ended up at .3555 the bore riding portion should be about .356?or should it be .3555 and just skim the bore? and then i'll go .001 over bore or a bit more for groove. I know that some rifles do well with boolits sized .002 over groove, like my 45/70

    I know that older military rifles that have lots of wear and tear (worn out throats) will require a larger nose.
    Lets say a new .308 likes a nose of .301"
    An old WWII '03 might need a nose of .304"
    A pound cast will tell you what your rifle needs.
    Hope this helped.

    It really all depends with how the end of your chamber ends and how the lede transitions into your riffling. It wouldnt be hars chamber, but you would notice with seating depth. The bullet picture you posted. If i am reading it right has a bore riding section that is .356 which is that same as your bore. A light engraving of the bore riding section i doubt would hurt much.

    The lightest scrape possible, to avoid set back.

    I was happy with the witness marks, that my Mod 70 put on this Lee CTL312-160-2R

    the scuff marks work okay.
    I have a couple that are probably close to .001 per land mark.
    but if you have say a 300 bore a 301 nose would be just about right.
    you can fiddle your alloy to make the nose fit tighter or slightly looser.
    it's worth the trouble and I prefer a little harder alloy to make a tighter fit.
    bore ride bullets rely on that long nose to do most of the work, the back half follows the nose and gets steered at the muzzle.

    that's why I added .06 to the forward groove riding band on that boolit, to give it a bit more grip. im sure with tom if I give him the correct info, and alloy it will work out ok, I just want to avoid having to nose size!

    On a lot of my boreriders, the front portion needs to be about .010 smaller than the base of the bullet. On a recent buy from NOE the bore riding portion is .301" and the back portion is .311".

    that makes sense, now that I think about it, I see a lot of bore riding boolits, what would a non bore riding boolit of the same weight look like? would it be like the lyman 35-200? if so, to get a 286gr boolit in a 9.3 it would have to be considerably longer, not sure if it would even work with the somewhat short neck of the 9.3X62

    you'll still have a bore riding section.
    but this would be a non bore ride bullet

    It depends too on your alloy hardness. My 200g .30 cal requires either softer alloy or nose sizing depending on which rifle I shoot it in. This was done on purpose (Believe it or not) since it would be used for several different calibers and rifles. With some alloys a .001 is just too hard to seat without set-back into the case. Not a problem, Just nose size and go. With the softer alloy it does just fine.

    just a bit less hard than #2 but a little tougher. I cast 2 boolits last night, and tonight I will re-measure, and again tomorrow night, to see if it shrinks, grows, or stays the same. mmost alloys shrink a little, but I have heard copper makes them grow a bit, not sure how much copper they were using. maybe popper will see this and reply

    No, the NOE size die fit into a holder (From NOE) that thread into your reloading press. You can get the adapter for the Star sizer, but it is just for sizing only unless you modify it for the lube. I did that to mine so I could lube my .17 cal cast bullets in my Star. But they do not make an adapter for the 450.
