Re: Resizing Video

In your line of work as a gunsmith Matt how often do u set the customer up with a FLS die made from a “resize reamer” that matches the chamber reamer used to cut the chamber ? For a competition shooter/customer who wants to ensure everything is right this would seem a smart move ?

Re: F standard knowledge help pleaae

You might want to consider a second focal plane scope instead of the Strike Eagle which is a first. You’ll find at higher magnifications your reticle will cover too much of the target, making things more difficult than they need to be. I consider that a very practical reticle with good line thickne...

Re: Sweet's Oil

Sounds like a mine field Keith. So when barrel "x" won't shoot and everything else is all top notch ( lets say it's a serious F Open rifle ) does the gunsmith straight away measure the bore ? And if they do how often is a problem found ? Samples of the bullet to be used should be measured...

Re: Sweet's Oil

...Alan, it is my firm belief that a barrel that takes an inordinate number of shots to "settle" after cleaning is not clean at all... Keith, this is just a theory, but if you have a bullet that is a tad too small for the bore (or a bore that's a tad too big for the bullet), then maybe it...

Re: Sweet's Oil

Just out of curiosity - is there a reason to shoot the first bullet in a match with oil in the barrel...if so does that apply when doing load dev? I'm curious - I don't shoot with oil in the bore so maybe there is something to learn here (not sure I'm gonna change what has been working but interest...

Re: BARREL LENGTH AND TUNERS

Nah waste of time , I wouldn’t have one ! Good being naked ( barrel of course, what were u thinking hey?) , especially for me being of Scandinavian background :mrgreen: . Especially stay away from orings or anything harmonic dampening! [-X When Mark F came to NZ he just had one of those Sims "...

Re: BARREL LENGTH AND TUNERS

Re: Tuned barrel

Brett B put up a pic of his new F Open stock recently. I want to put a pic up of mine but buggered if I can start a new thread to do that, plus I just know the pics will be upside down. What to do ?

Edit : am getting some help to get some pics of my stock up on a new thread. Regards Rob Kerridge

Re: Tuned barrel

Interesting on the rubber flex system. I always had some doubt but must admit I never used one. When I went from wood > wood + pillar > (both with a compound > to Al V block I think it was a progression in the right direction. I think all can work well but the system has to be practical and robust....

Re: Tuned barrel

Yeah - IMO adding a layer such as what H&H did with the millenium isn't the way to go - but it is thinking the right way in that you want to dampen but you want to do that consistently. Materials inherent in the object i.e the stock or the action that provide the appropriate rigidity and dampen...

Re: Tuned barrel

“Benchrest Actions and Triggers” was 1st printed in 1983 and Otteson discusses/dissects seven BR actions and four BR triggers. In the 1st chapter he writes … “The importance of rigidity or stiffness in an action, particularly one used for benchrest competition, is widely recognised in the abstract. ...

Re: Tuned barrel

I shall scribble more after work but Stuart Otteson wrote a few really cool and beautifully written books about rifle actions, analysing them from a mechanical engineers viewpoint. In one small volume he analyses a few target actions and triggers. Bloody interesting. Perhaps dated now because there ...

Re: Tuned barrel

Here's some more really basic physics that relates to the above banter : with all things equal ( yes I know that's relative ) why might a gun that's heavier have an advantage ? Here's a clue : heavier means a greater inertia value which means the object has a greater resistance to movement. I wonder...
