I use the grinder that is on the picture beside the stock. Grit 50 sandpaper, dust collector, and I finish with an orbital sander

Thanks for the information. That looks like good work for "free handing" the dimensions.

Do you think the same tools would work for balsa laminate? I want to make a carbon fiber stock along the lines of a Scoville, but need to make up the core to be wrapped. I am not too sure how best to shape the balsa core. I guess I will just need to make one up and give it a try.

Fergus, Have you considered trying a Surfoam rasp style tool to do the rough shaping of the balsa?

Yikes, what happening to the margins???

Ray,
Welcome!
If your experience in discovering benchrest shooting is anything like mine you will get enormous fun and satisfaction from it. Good luck and once we know what area you live in you will probably get offers of help.

Have fun, Mike   

My suggestion is to read the rules first so that you don't head in the wrong direction with your bench equipment set-up. It is not clear to me how working outside the rules is to any advantage anyway.

Without presuming to know would be best for your needs, I have found that the finer sand used for sandblasting will usually make the bag heavier than when filled with 'playground' sand. Sand sold for sandblasting is readily available in different grain sizes and is very affordable. Auto supply stores often have some or can tell you where to get some.

Re powder chuckers (chuckle yes throwing charges is perfectly OK although a scale would still be needed to get a weight for a given setting. The one I see most often at the races is the Harrell's measure but there are other good ones. The ones with a micrometer insert make it easy to return to a given volume.
The Lyman 55 is very difficult to repeat a setting without the help of a scale. The humble Lee Perfect powder measure rates very well for consistency although durability might be lacking.

As far as where to buy, there are several Canadian sources that mail order and you probably already have a Sinclair catalog no? Canadian Access is a good monthly to subscribe to for gun stuff in Canada.

I bought my Barnard action from Robertson Composites in Ottawa.  

On the jam question, it is difficult to give you a measurement on where to start but this is what I do. With a case fired at least once so it has some carbon inside the neck, sized as you intend to do it but with no primer or powder, seat your bullet of choice long enough so that the bolt doesn't close. Set the bullet back .005'' at a time until the bolt closes with little effort. The idea is that you do not want to have to wrestle the bolt closed and upset the rifle in the bags on every shot. Take a second unprimed case and fresh bullet seated with the same setting that previously gave easy bolt closing and chamber again. Remove the round and check for marks from the lands. If all the lands are marking evenly around the bullet then I would say that that is your maximum jammin'. You can refine the process or setting but it is important that the round chambers easily and that the bullets don't stick in the lands if you unchamber a live round.  

Gringo,
Been using Dan Opel's 64.5 gr. in my 6BR with either H322 or N135. Lapua brass and chambered with JGS no turn reamer (No. 1262).

Bonne chance les boys et aussi à toi Vera.
