Well, I'm going to leave the buffer washer out so anything is possible! I'm tweaking the 'tricky' .177 calibre for this Meteor conversion. I'm aiming for 10.5 and pleasant shooting, if I can get 10.8 then I will be crazy with joy. Taking the rolled & wrapped early model Meteors to 12 ft/lbs in .177 is just wrong but Bowkett was pushing the envelope in those days.
BTW I will post the Rowan trigger in the morning, had a problem with the deep fried Mars Bars that got in the way of the post office (St Andrews Night) today.
