  1. I have been incredibly impressed with the Freyr and Devik mods from Edinburgh Rifles.

    https://www.freyr-devik.no/products

    They are incredibly lightweight and very quiet indeed next to other mods (the larger ones more so than the smaller ones as you would expect). They also have titanium innards so they shouldnt rot away. We have two in our household (196 on a 308 stalking rifle and a 280 on a 6.5x47 PRS rifle) and I would consider another like a shot!

  2. Here you go, it is based on the default data off QL so bear that in mind. As always start low and work up, may not be safe in your rifle etc.....

    I assumed a 25 inch barrel as on a CZ 550. Dont know what the case capacity of Winchester cases are in comparison to the QL default case capacity.

    Hope this helps

    Cartridge O.A.L. L6: 3.600 inch = 91.44 mm
    Barrel Length      : 25.0 inch = 635.0 mm

  3. Could I pick the UKV collective brain please. 
    Like many others I strive to obtain the best results from my handloads and aim for concentric ammunition. There seem to be two methods of measurement of concentricity, those that reference off the case wall such as the Sinclair comparator and those that reference off the cartridge long axis by centring meplat and case head such as the Hornady. Is one better than the other? It strikes me that a non concentric case (eg small dent) could result in an indication of excessive runout whilst the bullet could be perfectly aligned with the long axis. Would the Sinclair type be better for assessing case concentricity and the Hornady better for assessing concentricity of loaded ammunition?

  4. Have you used a Redding shellholder with the Redding die?  From the photo I suspect not. Could be the shellholder being poorly matched to the die? Possibly try a Redding shellholder? Have heard of folk having the bottom of the die shortened for this problem before.

  5. Ok so using my applied Ballistics taking the Facebook method aka riflemans rule the app gives me a correction of 7.2 mils at 0 deg of elevation and 5.6 mils at a range of 692 m at 0 degrees of elevation. 

    Taking the original elevation of 7.2 mils and multiplying by cos (30) =0.866 gives 6.2 mils of correction 

    putting the angle of elevation of 30 degrees into applied Ballistics with 800m range gives a scope correction of 6.1 mils. This is clearly far closer to the improved riflemans rule providing of course Brian Litz has done his sums properly (which I bet he has)

    After you with that 5-gallon tin of glue 😁

    OK - if you fit a rifled barrel to either a Pump Action or Self Loading shotgun = it then legally becomes a RIFLE
    What's the legal status in the UK for Pump Action rifles or Semi Auto rifles (other than .22-rimfire?) = SECTION 5 = banned for mere mortals and not allowed for TSG/PSG type events

    The consensus around even rifled choke tubes is that they better be avoided for the same reason - namely they might make the gun Section 5; this may not be set in stone yet, but anyone want to be the guinea pig in a legal test case to establish legal precedent??

    Single or double barrel shotguns - or maybe even one of the lever actions?
    Don't see any issue with them having a rifled barrel - and these barrels also can be sub-24" length as they'd no longer be on SGC - which means the min. 40" length for all semi/pump shotgun rules similarly don't apply

    Just not sure how competitive some of the latter may be. Don't think many of the lever action models are around as yet.
     

    Ahhh yes I forgot about that !! 😕

    so a bolt action rifled shotgun would therefore be legal? 
     

    At least you would get free accommodation for a while !!

    That’s just joke haha £300 entry fee (?not sure if I’ve read that right ) haha 

    I can shoot any of the British or English Open championships clay shoots for £50-£60  entry 

    and there’s a lots involved than  just setting up some steel targets. 
    john no matter. the cost of PRL can’t be justified. Well not with a straight face. 
     

    anyway the question was

    “ what would I change “ and there is my answer. 

    I wonder how many automatic traps are involved with one of those big clay events.... and the cost of those would be.... hundreds of thousands. Not to mention the staff costs ground hire and cost of clays and infrastructure to keep the traps fed. Surely way more than 50 steel targets you would assume

    It's already been sort of hinted at in an earlier post - but there are THREE horses in this race. 
    I am not connected in any way with any of them, though I have met them all at an EskdaleMuir Shoot.

    The FCSA have stated their position, as has Marc.
    It may be that they are both 100% correct and both a true reflection of what has happened to the range facility.

    The silent party, and the one who legally holds all* the aces, is the landowner = his land, his say-so as to what happens with it & on it - short of compulsory purchase orders for new runways or housing estates..!

    While the landowner is unlikely to be on such a forum as this one, I feel that the lack of input from that side means that we are all the missing a big piece of the jigsaw.
    NOT saying that it is the case here, but it would not be the first time a club has cleared the ground and set up a nice facility, for the landowner to then turn around and offer it to another group who are paying a small dividend more than the club that did all the graft. Seen it directly & indirectly quite a few times...


    * other than the extended danger area leases.
     

    This is completely true and it may be that the land owner has been significantly involved. Potentially this may well transpire to be to everyone’s loss, including his own, if the range cannot be used due to inadequate danger area.
