Prewar air rifle powers?

[scooter48]

I suppose it makes sense, Chris, that while some rifles just refuse to get up to 'average' power for that model - I once spent weeks trying to get a Feinwerkbau Sport above about 8 ft/lbs - others are always going to be unaccountably powerful.

But before anyone gets their hopes up that prewar BSAs somehow routinely achieve these exceptional power levels, be aware that the overwhelming majority of 45in rifles stay stubbornly at around 9 or 10 ft/lbs. give or take, which is surely more than enough for such venerable old ladies/gentlemen.

I don't know what the old Lincoln Jeffries that Terry Robb tuned in the early 70s but it was the most owerful rifle ive ever owned. I sold it to a gun dealer in Southend and he snatched my hand of it. It also had a no 12 aperture sight. Ive had many rifles since but none came near this gun for power.Idont know what he done to it.I currently have about 30 rifles,mostly BSAs and vintage.Love this forum.
