Totsy Posted October 28, 2012 Report Share Posted October 28, 2012 Are there any? Im just checking becasue at first glance I am getting very good patterns at 30m with 3/4 choke. I assumed that heavi-shot would pattern better with more open chokes similar to steel. Ta, Lee. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted October 28, 2012 Report Share Posted October 28, 2012 well, hevishot being twice the hardness of steel, it isnt advisable to use excessive choke. it is advised to use chokings for steel shot. this stuf is extremely hard Quote Link to comment Share on other sites More sharing options...
Totsy Posted October 29, 2012 Author Report Share Posted October 29, 2012 It would seem that the lyalvale cartridges which I have use a malleable composite which conforms to CIP? I am assuming this allows similar choking to lead and bismuth? http://www.lyalvaleexpress.com/high-performance-max-game-hevishot-34-grams All the US manufactures seem to be using a hard composite?

Guest cookoff013 Posted October 29, 2012 Report Share Posted October 29, 2012 http://wildfowling.co.uk/magazine/hevi.htm there are so many nontoxics coming out, hevishot is a specific alloyed product. not to be confused with tungsten, itx, sinter, niceshot, eco tungsten, tundra heavy, tundra, powershot etc.... please research your shot types.

stalker58 Posted October 29, 2012 Report Share Posted October 29, 2012 (edited) well, I patterned lyavale hevi 70mm no4s at 40yds with cyl and imp cyl,from a browning maxus with a backbored .742 barrel diameter,and the patterns were bloody awful,could have driven a bus through them,never mind a duck! I then changed to Mod choke.what a difference that made,141 shot inside a 30ins circle,cut open a cartridge which made me cry,but I thought I would be scientific about this.160 shot in cartridge,which I make this about 88% inside 30ins circle.So you might be on the right track with your Imp Mod choke,or maybe its brownings backbore barrels and Invector plus choke tubes!
