Hi Fabs,
It's the front triple spocket which is the problem not the rear

I will probably have the boys at Cycle Hut take a look at it, might even get them to fit a new front tube and give the whole thing the once over, need new batteries in teh front light as well. Sort of winter service.
Anyway for now I can just pump up the front yre and use ti as it take several days to go down.
This morning it's quite bright virtually no wind so in a little while I will heading to the range. Got some 6mm rem loads to test and I think I will take the Browning A-5 and see if we cannot get the trap out

Will also try a decide what choke it has in the barrel (Fixed).
Will report back later as one shot is not really enough to base anything on.
