Here is my vote
for the cheapest/best combo. Get a Caldwell lead sled, don't use the elevation bar. Put a Caldwell "Rock BR" rest in front. <ul type="square">[*]sled from side 1
[*]Holland QD 3
[*]my bench in the back 4
[*]good look at Rock BR 5
This crapy forum software won't allow my [image] tag so here are some links to my setup. This is my 375 Kirby/Lilja/RUM with 30" heavy Lilja pipe, trigger job, excellent Holland QD break (kicks slightly more than my .243 shooting 260 gr Accubonds ) - It's a tack driver but I'm not posting results until I chrono it and get at least 200 yards out. (75 yard results don't count - if they did and I had a micrometer I might be able to tell my group size - I could tell I was not missing the page and hitting exactly the same hole as it got a bit larger each shot [img]/ubbthreads/images/graemlins/smile.gif[/img])
Notice the press wings that give you a really tight fit on the stock.
IMAO and using my mathematical theory, I'd skip the lead - go for the heaviest barrel (which will shift the moment forward where you need it to prevent <font color="purple"> The Magnum effect
</font> - also adjust the sled so the you are as close as possible (back rest) to the barrel axis.
GoodGroupers experience is worth 1000 pages of my theory tho, but I thought I'd toss out my vote.
