I don't make any claims that I am always right but I have a done a lot of chambering over the last forty years. I have used flushing systems and liked it fine but I am perfectly happy blowing out the chips, inspecting the reamer, re-oiling, and going again. On a typical hunting barrel, I rough...

Not mis-remembering but perhaps misunderstanding. The Remington is a sealer. In the event of a castastrophic case failure, the bolt nose is supposed to expand to seal in the counterbore and this is just what it does. Reducing the clearance makes the system more effective, not less. I have fitted...

I dislike bipods on general principal so prefer to not use one. I can shoot with a sling and sandbag support or I can use a pedestal rest with two feet (BI-pod) which is loosely attached to the rifle (lanyard). The whole bipod thing is antithetical to the original intent of "F" class. The...

Yes, .002 is the normal allowance for crush. The use of the dial gauge to verify clearance is certainly just fine. For myself, I figure clearance is clearance. On match rifles I'm happy with .005, for hunting rifles, I want .010. In reality, I likely end up with .003 and .008, respectively...

I think I would have to tape a five dollar bill to it to get someone to steal it. I guess I wasn't clear enough when I ordered it. Regards, Bill

I suppose it could but it is easy to measure the Remington and simply cut to the measured depth plus .005". On a coned breech, I cut the cone a bit shallow then I put the bolt in the action in the closed position then screw it onto the barrel. I check the gap between the reeiver and the barrel...

A year or so back, I ordered a 257 throater from PTG and got a uni-throater in the mail. I took one look and thought, "what the heck is this?" I sent it back and wrote that I wanted a simple 25 caliber throating reamer. I ended up with a throater for the 25 ACP! Now I was just pissed off so I...

I cast glass pillars rather than using aluminum. I have built a couple of "F" class stocks for which I made aluminum bedding blocks (model 70's) and it worked out OK but the other half dozen which are bedded in glass with glass pillars work at least as well. My theory has always been that the...

That is, for the most part, correct. If the chamber was cut with no throat at all, the amount to be cut can be measured quite precisely. If the chambering reamer has an integral throater but this is found to be too short, it is a little more difficult to measure and cut as precisely. This is...

I like the looks of that rifle. I like Model 70's and have two F/tr and one prone match rifle (a 30/06) built on Model 70 actions. I think the FN actions are very good; probably better than any earlier Winchester actions. Regards, Bill

The late Bob forslund once told me, " If a BR rifle, with good bullets and any reasonable load, doesn't shoot reasonably well, there is something wrong with the effing rifle". Changing components isn't likely to turn a 1.5 moa rifle into the .4 moa rifle it should be. There is something wrong...

Looks pretty nice to me. You'd better get out and shoot it. Regards, Bill.

A little longer but not a lot. I bought a 40X-BR at an auction once. I didn't really care about the barrel since I planned to replace it anyway and I figured a 40X should be too badly abused so I was happy enough when I got it for 375 dollars. When I took a closer look, I found the barrel was...

If you are unable to identify a shot out throat, have someone who can do so give it a look. In general, look closely at the rifling just ahead of the chamber. Now, reverse the barrel and look closely at the rifling near the muzzle. You will probably notice the rifling near the muzzle appears...

Ron, No shoulder fired rifle cartridge will produce fifty thousand pounds of back thrust. A cartridge which produces 50,000 psi and is of .308 size will produce around 6,000 pounds of back thrust. Even at that, the figure seems a bit excessive to me but this is what Stuart Otteson claimed in his...

Those I have seen which were prone rifles were marked 7.62 Nato; probably to ensure suitability for Palma competition. A 40XB-BR was stamped 308 Win. I honestly cannot tell you if there were difference in chamber dimensions but I would think there were however, the differences would be minor and...

Just looking at the wear on the forearm from a shooting glove, I'd say it has seen some shooting. Interesting to see what's left in the barrel. Those are excellent barrels, by the way. My Dad had the same rifle but in single shot form. Still has it, I think, but with it's third or fourth barrel...

Bullet length.

Twist will work great for bullets like the 155 Lapua or the 155 Bergers as well as any of the VLD-styled 168's. I have shot 200 MK's in a twelve wist with no issues but I think it's a bit slow. With a scope mounted, that 40X is the epitome of an F(TR) rifle. What's more, it is a solid platform...

On the 788, it is mostly compression of the bolt but there is also some stretch of the receiver. In total, it amounts to about .001" per thousand pounds of back thrust. In comparison, the deflection of the Model 700 is less than .0002". There is no reason to think the lugs would deflect any more...
