WOW?,... this is amazing how many ideal and theories there are on safe / unsafe usage of cruddy salty ammo there is?!?!?!
pro's and con's time
chrome lining while sounding cool and super-duper bad ass is all well and fine all it offers is a bit of resistance to the "corrosive" nature of the ignition-salts in older ammo, here's how it works,.
as the powders are set off and the action takes place the fast burn off of the chemical mixture leaves a powdery residue in the barrel of the gun,.. if left for any length of time, not hours but days, weeks, the moisture in the air is attracted to the salts and will create residue (like your cars roof over night in October) and it will sit on bare metal and eventually create mild rust and left for even longer pit the surfaces,..
when the gun has a chromed liner it reduces (not eliminates) this from taking hold,..
the down side is when a barrel is going to be chromed the machining of it is sloppy to account for the chromes thickness added in the finished equation and being chroming is an unexacting science the thickness varies, and therefore the accuracy suffers from a looser fit of the bullet,... and as pointed out a few posts back the chrome will wear out changing the fitment of the slug as it makes a pass down the twist,..
the non-chromed is a tight tolerance and will be precise when fired as intended,. the ignition cap salts are just like sand on raw steel left out side, it will hold mildew IF YOU LEAVE IT IN A DAMP AREA and let rust take hold but take five minutes to wash out with Windex (ammonia) drag a shoe-lace type $10 barrel rope (with brass barbed scraper section) through it 3-4 times dry thoroughly and dampen down with gun oil (light) WD-40 type non solvent based liquids and the gun will out last you and a non chromed one will last longer in an accuracy challenge if you are wanting it to be that,. if lazy ass-hat's with no brains want chrome liners due to leaving it in the wood shed and expect it to shine when needed?,. they prolly shouldn't own a friggen gun in the first place!!!
don't fear what you don't understand,.. understand what you're fearing and it's not so scary
I don't own a pile of old guns,. but I took time to figure out why million's of solders in early wars could drop an SKS in the mud, piss the sand out of it with last nights wine and blast thousands of s**tty rounds through it killing hundreds of enemy solders with it?,.. and why in Iraq did many US troops dump AR15's in the dirt, pick up AK's they found buried and used them when the mighty M16's jammed to keep in the fight?,.
must be something to it ya don't know eh?
My opinion?,... buy ether but don't fear the other one by misunderstanding what chroming means?
personally?,... I'm going to get a 858CZ,.. and I'm selling my Kel-Tec RFB in favor of one,. so yes I believe in that design that much!
Chop on!
UPDATE!
just got back from my local boom stick store,. put up RFB on consignment and while I was there they had in some VZ-58's and an ass load of CZ-858's,.. I bought an 858 while there, right off the un-boxed shipment BOOYEAH!!,. (where's my fab defense catalog now?!?!?!)
P.S. NON CHROMED!!!!
