Re: Ogive to base measurement.

Base to ogive can be very useful when comparing lots. Some lots are significantly longer .2-.3 and thats enough to require a new work up as it would indicate significant dimensional differences that could alter pressure significantly Base to ogive has no relationship to seating depth - in fact IME t...

Re: Ogive to base measurement.

depends on what you are wanting to achieve if these are boat tail bullets.
2 Thou is fine for a general measurement - on boat tails it won't tell you where the variation is but it will catch outliers.

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...

yeah I don't mix chemicals - who knows how they react or what compunds they form.

Re: Sweet's Oil

Kroil does the same thing. Its not rust. I find it takes a bit more than one dry patch to clean it out.

Re: BARREL LENGTH AND TUNERS

Avoid the stress of a tuner - of course - they are not essential items - you can tune a rifle without one. Are they stressful - IMO nope - we make it hard - heck you can put one on and never touch it if you wanted to. Yip length is about FPS to get to the next node without over pressure....nothing t...

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 dampeni...

Re: Tuned barrel

I think its more a question of how rigid is rigid and what absorbs those vibrations - the racing example puts a huge amount on the suspension - making everything rigid would be very bad and unusable. A Barnard P is probably more rigid than a Panda F-class but there is an interesting concept around t...

Re: Tuned barrel

Limitations placed on equipment by overzealous weight restrictions have resulted in a search for extremely light stocks. To retain what was once 'normal' stock rigidity in these very light stocks now necessitates carbon fibre shells and strips. Some call it progress but I am not so sure. Maybe on a...

Re: Tuned barrel

I do think rigidity is a thing that is needed in a stock - we cant shoot off wet bits of cardboard or a pool noodle but... Is rigidity the larger factor in a stock design or a necessary derivative due to heavy bullets driving the thinking in terms of long stocks and low CoG? IMO length is counter in...

Re: Tuned barrel

Some thing I have seen of recent more flex from barrels and action than stock flexing. Long stock versus a short stock what is best ? That's something else to think about. Bipod positioning on the forend. Rear bag and front stands were does it all stop or were does it all begin . with holes in pape...

Re: Tuned barrel

OK here is one for the experts. You have a tuner on a barrelled and scoped action in a vee blocked stock, the rifle is as accurate as possible. Now you change to a heavier scope or for this example the vee blocked stock your using is swapped for another vee blocked stock which is lighter. Now will ...

Re: Tuned barrel

Its a weird world - I have a flexible stock (or do I - so how do you quantify and measure flexible - the thing we all reckon is bad) - my scores and x counts at regionals and nats suggest its not a problem and that just maybe its the whole package.

Re: Scales

I use a beam scale and an A&D. the beam scale I use is a tuned one in that it is very sensitive and will register 1 kernel. The A&D still drifts for me. I have certified check weights for the A&D which I also use on the beam scale. I like that I can compare the two on any given day and o...
