duke5339 Posted July 13, 2012 Report Share Posted July 13, 2012 Just a quick one, has anyone found that Beretta Al391 Tekny are fussy about cartridges? i picked up a 1995 model and it seems not to like kent velocity, but my other auto a hatsan marine will cycle any thing i put through it!!

duke5339 Posted July 14, 2012 Author Report Share Posted July 14, 2012 i wonder if they need to bed in, the one i have seems like it has sat in his cabinet all its life. Quote Link to comment Share on other sites More sharing options...
littlerob Posted July 14, 2012 Report Share Posted July 14, 2012 a brand new one the book recomends that you use 32g about 250 to 500 cartridges to bed them in Quote Link to comment Share on other sites More sharing options...

duke5339 Posted July 14, 2012 Author Report Share Posted July 14, 2012 I will try some 32g see if it will loosen up Quote Link to comment Share on other sites More sharing options...
BlaserF3 Posted July 14, 2012 Report Share Posted July 14, 2012 Have you tried cleaning the gas ports in the barrel? I have a 391 which cycles 21gm with no problems. Quote Link to comment Share on other sites More sharing options...
humperdingle Posted July 14, 2012 Report Share Posted July 14, 2012 My (approx) 2000 Urika 391 seems to cycle anything 28g and over. If I put 24g through it, i'll get a jam every 50 rounds or so. Just make sure it's kept clean. Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted July 14, 2012 Report Share Posted July 14, 2012 My Urika /Teknys cycles 21gram carts reliably Quote Link to comment Share on other sites More sharing options...
Rimfireboy Posted July 14, 2012 Report Share Posted July 14, 2012 My al391 teknys has never jammed, it's 20 bore though, so maybe it's not a good comparison. I usually use express super twenty's but it's not fussy. Quote Link to comment Share on other sites More sharing options...
duke5339 Posted July 14, 2012 Author Report Share Posted July 14, 2012 Thanks for the replies, i strip it down to the trigger after every shoot. i have changed the recoil spring and the loading gate, but it fails to feed i would say 10 out of 25 kents with the brass not lifting. The spent cartridges are been thrown a good 2M away. Quote Link to comment Share on other sites More sharing options...
duke5339 Posted July 14, 2012 Author Report Share Posted July 14, 2012 One other thing i have noticed is that i seems to like shorter cartridges better, i tried 21g gamebore and they cycle fine. Quote Link to comment Share on other sites More sharing options...
duke5339 Posted July 22, 2012 Author Report Share Posted July 22, 2012 Just a quick update, i have noticed that the second catridge is failing to be fed all the way into the loading area. looking at it, the cartridge is normally fed rearwards until the breech bolt release guide locks onto the catridge, but when i have the ftf it has aprox 3/5 mm to go before it reaches the locking catch. everything is clean and lubed. Any ideas? Thanks Marcus Quote Link to comment Share on other sites More sharing options...
