I've got a standard Accu-Trigger on my 12FLV originally in 308win.... I thought the trigger on the Varmint models was supposed to go down to about a pound.... I'm not certain, It's been a while... The trigger on mine only adjusts down to about 2 1/4lbs, Is this normal? It's a little heavy for my taste..... Any way to shorten the spring without ruining the trigger.
