finally set up the Dillon RL550b yesterday and reloaded my first batch of ammo, quite pleased with myself to be honest.
i had the help of a fellow club member who has shot nothing but .45 and his input was invaluable.
Tested the ammo today in my Sig and shot a three shot group standing at 15 yards and was within 1.5 inch group then went out to the 20 yard mark and finally drilled one right through the centre of the 2 inch square piece of paper. The others were in the A zone but I was working on groups so was only happy with the last shot.
loaded 100 rounds using 4.5 grn winchester 231, federal primers and cases with Best 230 LRN. loading books indicate MV of around 765 but I have yet to chronograph this load. At least I can now afford to keep shooting. Thanks all for your help in my other thread.
The rounds fed without any issues whatsoever.
