TXMXRACER Posted December 8, 2009 Share Posted December 8, 2009 Can you run full power slugs thru a FN with the light piston without hurting anything? So far I have just been using low recoil but I have a bunch of full power stuff I could use for practice. Thanks for the help. shane Link to comment Share on other sites More sharing options...
Hartmann Posted December 8, 2009 Share Posted December 8, 2009 (edited) Yes. Mine shot them (Remingtons) just fine with the light piston. As I said in another post however, I found my SLP shot the Fiocchi low recoil slugs better than it shot full house slugs. YMMV.

usp45ss Posted December 8, 2009 Share Posted December 8, 2009 The light piston is rated for 1 1/2 oz loads and under. Typical slugs are 1oz. Not sure if the 1 1/2 oz applies to shot only loads and not slugs, but I haven't had any problems out of mine. Link to comment Share on other sites More sharing options...
JWS61 Posted December 9, 2009 Share Posted December 9, 2009 I started out with the light > 1 1/2oz piston and it seemed pretty harsh (on me and the shotgun) shooting full power slugs so I tried the heavier piston that came with it and it was allot nicer to shoot the full power slugs (fiocchi 1560fps etc). With the heavy piston in I tried the Walmart Winchester value pack birdshot that I use for practice and it continues to cycle without any issues. From other stories I have heard maybe I just got a really good SLP Mark 1 or keeping it really clean and lubed pays off...

Hartmann Posted December 9, 2009 Share Posted December 9, 2009 I started out with the light > 1 1/2oz piston and it seemed pretty harsh (on me and the shotgun) shooting full power slugs I found this as well, esp. compared to my Vang Comp'd Mossberg 590A1. That was one reason I went looking for a reduced recoil slug. Link to comment Share on other sites More sharing options...
TXMXRACER Posted December 9, 2009 Author Share Posted December 9, 2009 Thanks guys. I guess I need to see if mine will shoot my birdshot with the heavy piston. I'm more concerned with damaging the gun at this point. Link to comment Share on other sites More sharing options...
JWS61 Posted December 9, 2009 Share Posted December 9, 2009 I have good luck running the remington reduced recoil slugs on targets out to about 50-60yds and then for the ~ 60 to 100yd targets I go to the fiocchi 1300fps slugs or in some cases the fiocchi 1560fps slugs to really reach out there and not have to drop them in like mortar rounds.

From other stories I have heard maybe I just got a really good SLP Mark 1 or keeping it really clean and lubed pays off... Just my experience, Jeff This is kindof worrysome as it seems "over-gassed" with the low-power piston. If the "heavy" piston will fire bird-shot, then firing anything but low-recoil loads (beanbags, etc.?) with the light piston would be asking to cause damage similar to the broken pistons suffered by the early Benelli M4's that used the 4-port system, no? I don't own an SLP, but this is just a thought. Feel free to point out my error. Link to comment Share on other sites More sharing options...
Lance Jensen Posted December 10, 2009 Share Posted December 10, 2009 A friend just suffered a broken light piston on his SLP. He was shooting Federal flight control 00 buck... Something to think about Link to comment Share on other sites More sharing options...
WS6 Posted December 10, 2009 Share Posted December 10, 2009 A friend just suffered a broken light piston on his SLP. He was shooting Federal flight control 00 buck... Something to think about The SX1 suffered broken pistons often, and it just worried me that the system doesn't have a better self-regulation/relies on only one piston. I will not be getting an FN, this answered my question from another thread. Link to comment Share on other sites More sharing options...
JWS61 Posted December 11, 2009 Share Posted December 11, 2009 Good points, I have heard about but have not investigated the piston reliability mod that some have mentioned here on the forum. I believe that they remove the spring from the piston and substitute an aluminum sleeve. Maybe someone else can chime in with the details since I have not looked into this yet.
