I never had any luck with the Lee bullet but have seen posts from people that have. The 2 lyman bullets you have been shooting are proven bullets,I have shot them and know they will work.

Klaus,

Just my personal opinion - I don't like deep grooves, as the lube at the bottom of the grooves doesn't do anything.   Well, except sling off lube when the bullet leaves the barrel, which cannot be the intention.  I prefer wide, shallow grooves - wide, in order to have as much lube contact with the bore as possible.  And also to make sure the minimum amount of lube  required has a maximum effect.
With very deep grease grooves, there's a lot of lube that has no useful purpose other than splattering on chrono skyscreens...

john boy had good results with that bullet in his 1000 yard testing with various bullets, powders and loads a few years back.  i have that mould and so far have only used it at 200 and 300 yards with good results - the load and rifle are both better than my aiming, but the bullet holes in the target face were round.

if yer targets are 200 yards or less, i would suggest the lyman 457193 mould and 1:20 or 1:30 alloy.  extremely accurate, and a fave of some top silhouette shooters as a chicken round.  i use it for 200 yard matches loaded with 62.0 of swiss 1-1/2f, and that mould will drop @ 415 grains with 1:20, so yer saving a bunch on lead, too.
