I realize seeing this image gets old but in the interest of reducing worry about not getting small, bottle neck cartridge SD numbers;
This 100yd 5-shot group's SD was 89!
PS: The bullet was the 225 FTX loaded to 2.12 COL and taper crimped down into the cannelure. Shot from a factory Bushmaster 20" upper, wearing a Ross brake, off of a bench.
You can get these bullets from numerous sources for around 26¢ each. Even less if you watch for sales and factory seconds on Midway. A little over a year ago, Midway had Factory seconds for something like $16/100 IIRC. Dawg, you bought some right? Needless to say, they sold out very quicky, so check the Facory Second page at Midway every few days. Ditto for other 45 cal bullets.
They may be a little overspeed at 38gr of Lil Gun but this test round held together in a water shot:
