Graybeard Post LBT Vrs Keith
There is a long post, some of it heated, on the Greybeard site under 'Ask Veral'.
The bottom line is that Veral even admits after a long discussion that there isn't much difference in performance between the LFN and the Keith style as they both have about the same metplate (65% I believe). He believes his design is more accurate, might be, but I know you have to drive them hard, where as the Keith works well over a large velocity spread.
Normally it is realitively easy to get a 'Good' load out of the Keith and most guns will shoot them well, where as the LBT style is a different story.

More reading assignments for the class...
Everyone who has posted in this particular thread needs to get the current issue of Handloader and read Dave Scovill's column titled "Proper Bullet and Chamber Fit".
It mentions the problems associated with using too hard of an alloy, why not to have round bottom lube grooves, throats, chambers, obturation....
An excellent read.
