    Great video and gets into the nitty gritty detail of lock-time and so on. Highlights that stock and trigger and important inputs too.

    Just curious if a five shot group is sufficient for these purposes? Because; statistics.

    The debate over 'accuracy is purely the relationship between the bore and the projectile' is an interesting one. I think that this is just one component of the accuracy potential, that of the just exactly what has been stated, the bore and the projectile. Unless shooting is being done from a clamped barrel - where is the fun in that? - the actual accuracy potential is that of the complete package as a rifle or pistol is ONLY used in the hands of a human. So a systems-level assessment ought to be made. For example, if you wanted a near-recoilless springer to increase your own particular accuracy with a rifle, you could add weight to it .. but only to a reasonable limit. A 25kg springer would sit very steadily on firing and give superb accuracy, but there are very few people who could bring such a rifle to aim.

    This video illustrates that the rifle and shooter form a system that needs to be tweaked to get the best accuracy, it's not all about the bore and the pellet.

    That 5 shot group is pretty representative of my rifle so I’m fine with that, and it was the only group I shot.
    The other rifles were shot a couple of times and the groups were always similar.

    For the flow of the video I wasn’t going to have loads of footage of shooting the targets, that gets pretty boring in my opinion.

    I filmed the shooting parts back in the summer out of curiosity and it developed from there really.

    I should have mentioned weight difference but didn’t weigh them at the time, surprisingly, without the scopes & mounts, my custom stocked Vortek 97 is only 100grams heavier than the listed black line thumbhole weight. Probably because Walnut is relatively lightweight wood. The standard black line 97 does feel deceptively heavy.

    My scope is obviously heavier though.

    Cheers,

    Matt

    So in terms of Drop in kits, how would you rate the vortex kits
    ive got a few fitted and love them, not got much to compare it to other than original

    I’m a big fan of the Vortek kits but I haven’t compared them to any others either so I can’t say.

    I’ve shot some very nicely tuned 97’s & TX’s belonging to other people, Paul Short & Tony Leach tunes seemed really nice to shoot, although I never checked them for accuracy.

    Cheers,
    Matt

    My experience of Vortek kits is that they are high quality, particularly the seals. They are simple to fit, the grease seems a bit 'sticky' but that seems to be an American thing.

    The actual performance is very 'sudden' even snappy like a gas-ram, but the accuracy of the Vortek 97K I have is easily on a par with my 77K which is fitted with a TBT kit, which is softer shooting, like a vibration-free standard system.

    Depends what your preference in in terms of a shot-cycle.

    Those two of yours that I tried on Saturday were most certainly very, very nice, sir.

    Watched the video last night. Excellent. Thank you for all the work you put into this once again.

    Very predictably, I really enjoyed the slow-motion footage once again. It's fantastic that you can gain access to this wonderful facility and share it with us.

    Must watch again and keep pausing next time, to compare the movements with the graphs etc.

    Thank you.

    Great video Dunk

    Really enjoyed it, I’ve always had a very big soft spot for the 97 as I’ve owned way too many over the years and have tried other folks setups in various guises of tunes etc.

    One thing I found really interesting was when you were showing that your hold changed shot to shot on the Black synthetic stock which really emphasised the need for being totally consistent with a well fitting stock ��

    Thank you, 35e Vortek/Britseals and 77Mk1 has a delrin guide and top hat of unknown origin - the guy I bought it from did tell me, as far as I can remember it was a drop in kit and not sent off for a tune, as you said the 35e just edged it, might be the 77 is in need of seals, might change them and see how it performs.


    I’m looking at my 97k - not done anything to it and was looking to improve on the Vortek but I’m not sure that I’ll get that with another make of drop in kit, Having my 80 Glided & guided by Shauny, it’s up there with the Vortex kit on my other 80’s, better probably, had to tell, I probably need a bit of a shootout between them.

    The appeal of the Vortek kits are the lack of heating and compressing the spring, then having to match a set of guides - not that it bothers me but the Vortek kits usually require a coil or 2 removing with a neat file & sand on the cut and it’s back together again, all are running Britseals all round - that combination seems to work and has been consistent across several rifles.

    I recently fitted the new steel pg4 kit in my 97, the original pg2 kit ran flawlessly for 7 years, just a relube after 4 years as the grease eventually goes gummy. I left the original pg2 seal in as it’s fine and Tony Burton sized it perfectly.

    Cheers,
    Matt
