20ga Weatherby SA459 cycling issues
« on: May 22, 2020, 05:57:42 PM »
I got a smoking deal on federal tss #7s and bought a bunch (1100fps) ive never been about to cycle the rounds....come to findout the SA459 requires 1300+fps ....

Is that normal? That seems like a hot load.

Is the mossberg SA20 the same way??

Just a thought.  Make sure you have the light load piston in and it is placed correctly and not upside down.   I had a few not cycle at first.  Bought a box of pheasant flight controls and shot a box of 25 and the problem was solved.

I've got a Weatherby SA-08, it often doesn't cycle the shell. Had it do this with both Federal Mag Shok and Winchester Long Beards, with the "heavy" piston.  Seems to not happen as much if I clean the magazine tube, where the barrel / piston sits on the tube, really well

I have two of the Sa459's, never had a problem with Federal Heviweights or my hand loads. As mentioned make sure you have the hevi load piston or sleeve in the gun.  I have chronoed my hand loads both are way under 1300fps, one is 1140 and the other is 1260.
