    A lot narrower/shallower rifling in the P70FT

    Touch wood iv'e managed to avoid the bug , hope you are soon up and about m8 , plenty of time for thinking !!!!

    About 5 years ago I got hold of a left hand P70FT that was absolutely fantastic could shoot 25o all day long, THEN in a moment of madness decided to clean the barrel.
    Only used a pull through carefully, it never regained its previous accuracy, it was ok, but it never shot 250 again :eek:.

    The trouble is that P70FT was the benchmark so ive been judging every other rifle against that first P70FT it's like searching for the Holy Grail !!
    The search continues ;)

    Yea, apart from positioning, the lighting is fiddling to say the least, Iv'e ordered a few opaque/milky 3mm leds to see if they remove the glare.

    Thought of using wired end filament bulbs instead of leds, will be easier to dim than leds

    Just upload a file, then select thumbnails or full size.
    I'm trying to find a clamp that will hold the scope securely and make it easier to juggle subject positioning and lighting.

    Its a 16mm one John, bought from Sure Shot.

    That was with grease, it was only a light coating of it, 3 or 4 pull thoughs cleared it out.

    My friends barrel is looking good so far. We put it on my steyr first and then onto his. Using known to be decent JSBs at 35 yards in mine the first dozen or so shots were in a dead straight horizontal line as it was a bit breezy. At 55 yards in both guns the main group of 20 shots was about 3/4" with a few random close fliers. With a bit of wearing in and pellet testing I reckon it'll close the group up nicely.

    You've seen all the endoscope pics we've been posting on another thread, right?

    Yes Rich , I have seen the pictures,but if you could use an Otoscope just to examine the crown and lead-in it would be easier than spending a considerable anount of time manipulating the microscope to obtain a clear picture and are considerably cheaper . Obviously the Endoscope are ideal for examining further into the barrels .

    I see what you're saying! Yes you're right. Using a long endoscope is kind of awkward for looking at the crown! Maybe time to go looking in the medical section of e-bay again!

    I found the biggest issue with taking pictures is the specular nature of the machined metal. You need lots of light but the reflections cause exposure problems all the time...

    Iv,e got one on my watch list, about the same price as some I've seen on various medical suppliers sites. Obviusly you can pay mega money for one , think most of the cheaper ones don't have a focus facility so that may be an issue .

    Might give it a punt ! if it doesn't work I can always use it to inspect lugholes for wax and spiders nests :eek: :D

    Did you rework either end or just machine to fit the steyr and try as is
