Salop Matt Posted December 10, 2016 Report Share Posted December 10, 2016 Folks, with Brownings is it only the Invector plus that are back bored or are the standard invectors also back bored ? Cheers Matt Quote Link to comment Share on other sites More sharing options...
BrowningB525 Posted December 10, 2016 Report Share Posted December 10, 2016 Only the invector plus out of those two. Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted December 11, 2016 Author Report Share Posted December 11, 2016 Cheers because I bought a 2016 B525 last month and it's an invector not an invector plus. It's for my game shooting and I only use fibre sad which I know some folk say back bored barrels lose a bit of performance with fibre wad so this suits me perfectly.

Westward Posted December 11, 2016 Report Share Posted December 11, 2016 Fibres work fine in overbored barrels - with the possible exception of the DT-11 on which the jury is still out. Quote Link to comment Share on other sites More sharing options...

ATB Matt I thought all recent models of Browning shotguns were Invector plus? My 2015 525 sporter was Inv + Quote Link to comment Share on other sites More sharing options...
B25Modelman Posted December 12, 2016 Report Share Posted December 12, 2016 (edited) The 2016 catalogue states only B525 Hunter 20 and 28 bore guns in the game range are Invector. In the clay range the B525 Sporter One 12 bore is Invector. But their catalogues have been known to be wrong.

figgy Posted December 12, 2016 Report Share Posted December 12, 2016 (edited) Check the sides of your barrel flats for the bore. it will state what they are. Edited December 12, 2016 by figgy Quote Link to comment Share on other sites More sharing options...
B25Modelman Posted December 12, 2016 Report Share Posted December 12, 2016 Also, if you look at the section of the choke that is actually inside the barrel and its about 30mm long, it's Invector. If it's about 60mm long it's Invector +. Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted December 12, 2016 Author Report Share Posted December 12, 2016 Its invector and stamped as such, my pondering was weather it is back bored or not ! Quote Link to comment Share on other sites More sharing options...
B25Modelman Posted December 12, 2016 Report Share Posted December 12, 2016 Its invector and stamped as such, my pondering was weather it is back bored or not ! so are you talking about your 20 bore or 12 bore Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted December 12, 2016 Author Report Share Posted December 12, 2016 20 bore...... I only ask as I was just pondering over the fibre wad game cartridges I use and thought that there probably isn't any real effect on performance from back boring that I would notice...... but it would be nice if it wasn't back bored so in theory better suited for the fibre game cartridges I have. I know my 12 is back bored as its invector plus! Which is perfect as its now my clay only gun and will only see plastic wads Quote Link to comment Share on other sites More sharing options...
Westward Posted December 12, 2016 Report Share Posted December 12, 2016 (edited) These guns, like modern sporting Berettas and most other modern guns are not back bored. They are bored normally but with a fractionally larger bore diameter. We're talking about a few thousanths of an inch only which causes no sealing problems with fibre wads. I've used many thousands of fibre wads through such guns and never once experienced anything that could be considered a poor wad seal. Back boring was often done to lighten barrels but has pretty much died out now that virtually every maker offers overbored lightweight barrels.

wymberley Posted December 12, 2016 Report Share Posted December 12, 2016 Fibres work fine in overbored barrels - with the possible exception of the DT-11 on which the jury is still out. The jury, indeed, is still out. In my bitter experience, it also depends on which fibre wadded cartridges you buy. Quote Link to comment Share on other sites More sharing options...
MrPhantom Posted December 12, 2016 Report Share Posted December 12, 2016 Must admit I never shoot plastics in my Ultra XS and quite happy with the kills I get with the fibres I use on clays. Trouble is you guys have now planted the seed of doubt in my head... Quote Link to comment Share on other sites More sharing options...
