Thanks for your help. I will talk to Sinclair and get more information on what you are saying concerning the different dies.

Adam,

sorry , i missed the question the first time , yes it is for winnie but no I haven't used it . Just wanted to develop aplan for a test of accuracy using fl bumped vs neck sized only .

So far it looks like winnie wont need anything but the Lee collet die till the cases need replacing /ubbthreads/images/graemlins/cool.gif

May your days ahead be blessed by the Lord of Light , Jim

No problem Jim, just thought id offer my redding body die for camparison sake. With the interchangable mandrels on the collet die, and the body die, im doing about the same thing... just in 2 steps. Runout stays the same with the body die, and with .001"-.0015" bump, groups are shrinking. the 1575yd group pic you saw from my rifle was shot with ammo loaded with this method, and .002" of bump. Haven't shot any with .001" further than 1160yds, but the results look promising. if we make another trip out to freds this year, I have high hopes for more 1k dogs.
The 7 is coming together, hope to have bullets out of it by the end of feb... time will tell.

Not to stir the pot again, but if you're going to shoot belted mags there's another dimension you should look at. After a number of firings, if your primer pocket doesn't enlarge enough to warrant disposal of the case, the base area just above the belt can enlarge enough to torque the case upon chambering. A quality or custom FL die will usually size the case a couple of thousands in this area and end a potental problem. But if you want to reduce this area to near new case dimensions, a speciality die will be necessary. I have one made by Innovative Technologies. Pricey, but very high quality and really works. It was discussed on this site a year or two ago. Might do a search if you're curious or go to www.larrywillis.com for more info.
