I was fortunate enough to find a virtually mint Birmingham Longbow, two months ago and, given what I had read here, bought it. It is pellet fussy. It likes the old H&N Pointed (as does my Omega, also bought this year, thanks to helpful comments here) - very tight groups but with reduced velocity. S.domes are not bad. I have just discovered from H&N themselves that the old Pointed are now H&N Spike but marketed under their 'Excite' label, ie Excite Spike, weighing in at 15.74g for .22.
I have discovered that the velocity is quite variable, depending upon the pellet. I have bought some more varieties of pellet to try out. Air Arms are not bad on the ft/lbs measure but this is a heavy pellet.
I should be interested to discover what you (and others) find works in terms of accuracy and velocity.
