Guest cookoff013 Posted August 19, 2017 Report Share Posted August 19, 2017 More than likely. There can be 2 subsonic. Speed of 1050 and loud Speed of 1059 and quiet in a moderated gun. It's to do with the powder. Quote Link to comment Share on other sites More sharing options...

getthegat Posted August 20, 2017 Report Share Posted August 20, 2017 920! Crikey that seems slow. I know they wouldn't be subs if not slow, but how is the hitting power and do you have to give bird's a lot more lead? Quote Link to comment Share on other sites More sharing options...
wymberley Posted August 20, 2017 Report Share Posted August 20, 2017 920! Crikey that seems slow. I know they wouldn't be subs if not slow, but how is the hitting power and do you have to give bird's a lot more lead? They're still doing OK. If you take 1ftlb as a base and compare them with a normal, say, No7, then the No 7 with the 1 ftlb (1450 at the muzzle) will penetrate between 0.84 and 1.52" at 43 yards and similarly the No5, 0.83 and 1.40" at 51 yards - at the 43 yards this would be 0.98 and 1.66". However, drop the 920 to 825 and it all goes to pot. This matches the 1 ftlb at 43 yards for the No 7 but the penetration is less - 0.84 to 1.42 which is reflected by their energy densiy levels of 87 for the 7s and 66 for the 5s. Oh, and yes, I'm bored. Quote Link to comment Share on other sites More sharing options...
getthegat Posted August 20, 2017 Report Share Posted August 20, 2017 Mmm... maybe you need to get out more 😀. I've not be able to get out much, do to work commitments, but with a new moderated and a load of cartridges that I've not tried before waiting to be tested, tomorrow may just be the day. I've got Various Lyalvale shells, no subs, with some HV 5s, Banger 6s! and some 7s with 24grm load. Target patterning at 30yards show an excellent pattern with both the 7s and 6s, much tighter and even than expected. Quote Link to comment Share on other sites More sharing options...
getthegat Posted August 20, 2017 Report Share Posted August 20, 2017 Oh and I'm now watching Country File, does that register somewhere on the boredom scale? Quote Link to comment Share on other sites More sharing options...
