Just curious to see what grain you guys are putting through your .40, and which grains you've discovered have hiccups! (If that .40 is also an SW40VE, so much the better!)
I've always used 165 grain Golden Sabers without a problem. I am now going to give the 180 grain Ultramax lead a go. Over the years I've moved towards heavier bullets..... and lead.
stick with 180gr bullets which are plentifully availible for reloading and lots of reloading data for them. tried 135-180gr bullets 135 @ 1150fps shoots like 9mm recoil wise otherwise its flat shooting. 150-155gr is little snappy forget what they are commonly loaded to some 1200fps. 165gr-180gr 950-1050fps however it is possible to get 180gr bullets flying 1150fps out of 4" bbl but dont want to shoot those without hearing protection unless you dont mind going deaf in future which would happen sooner rather than later.
