angle of lands out of throat

[buzzard]

I was wondering if any one had any experience or done any R&D work with the angles testing oscillation's with different angles

I talked to Mr kiff super nice Guy. He says 1min. 30sc. is best

If one were using a hot cartridge, would a shallower angle lead,pardon the pun) to less throat erosion and concequently better barrel life,at the throat anyway)?

He says 1min. 30sc. is best

What does that mean exactly?

it means 1-1/2 degree. he said minunte but meant degree.there 360 deg. in a circle. there are 60 min in one deg and 60 seconds in one minute. 1,296,000 seonds in a complete circle.______ treeman

Dan Lilja has an article about leade angles and the relationship with bullets. Take a look at his website.
