Ive been reading this forum for a short bit and have most of the basics covered, but <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o> </o> Im looking at buying a shotgun mainly for fun but potentially for HD also. I found a couple used police 870s at Buds but need some help. <o> </o> One is a 20, 7+1, standard synth stock for $299 and the other is an 18, 6+1, speed feed synth stock for $329. <o> </o> Is the speed feed stock worth the extra $30? How many rounds do they hold? Ive never seen one before. <o> </o> I was also kind of interested in an 18, 7+1, Mossy 930 SX they had for $583 but didnt necessarily want to spend that much (but I could swing it). <o> </o> Is it possible to effectively use a 20 or 18 for sporting clays? Can you add chokes to either the 870 or 930? Or would they even make a difference on a short barrel? <o> </o> Any info would be appreciated. Thanks.
