Richard - haven't managed to locate 147 GS's so far - will probably just try and go ahead with the five types I now have on hand and leave GS's for another time .. there are bound to still be some varieties so far not done.
Here is a pic of the five we'll do . Sorry, the white balance setting got somewhat off! I'll probably use this again when I write up test data, just for reference.
I noticed some difference in heights and so measured OAL's .. which are on the pic. Gold Dot 124's come out about same as Blazer ...... 1.124 ...... but strange that the Silvertips and both WWB offerings are shorter.
Book OAL is usually shown as 1.168" - 1.169" ... but this would be for a hardball. I guess with HP type bullets, and depending on ogive radius etc ... we have to imagine the bullet as if the ''missing'' part was actually there.
Anyways - we'll see how they perform soon now I hope.
Oops - forgot the pic .. Duh!
