4.7 grains of trail boss under a 180 grain grandmaster lead SWC. Very light recoil, super accurate, virtually zero leading. Surprising little smoke despite lubed lead bullet. Nearly full case of powder, but not compressed as I pulled a couple to ensure I wasn't crush'n the donuts... I shot about 100 of these this weekend and will be making a bunch more!
I have bought about 3000 pcs of brass for my G37. Some from gunbroker, some from leobrass.com, some locally. I have found it as cheap as $50 per thousand. I lucked out earlier this summer where at my local gunstore he was selling brand new midway gap brass (very cheap). He asked me to be sure I wasn't wanting 45acp brass. Yup! Thank you very much...
Reloading is very enjoyable hobby - you can try it out for not a lot of money. I still use the $20 press I first bought, then loaned to my brother-in-law, and he gave me back a couple years ago.
I ran a test and posted the results awhile back here on GT where I shot the same pc of brass 15+ times. My concrete driveway did a lot of damage to the brass (more than firing it).
