...I had one my friend,that was hards to beat,i shot a ported 665 Hasting,s Choke
win hv #6 shot,it would shread a turkey target at 40 yards best shooting gun i ever
had,money got tight had to sell it,but i did smooth the rear forcing cone myself
and yes there is a rear forcing cone,rough part located just at the end where shell
is put into the barrel,you look and measure that part you see it should be around three
1/2 inches long,and it will be left a rough cut...smoothing this with #000 steel wool
and polish cream,and you wont need a new choke,and yes you here alot of rip-rap
but this is a lenthened rear forcing cone..cut and lenthened from factory,but failed
to smooth it,trust me i have been shooting match for years and have cut and honed
alot of barrels in my time,so make sure you take advice from someone who knows
the ropes on shot-gunning.....thanks..hope i gave you some info on your new
remington that factory dont give,and yes i (MIC) and gauge all barral...
