Swaged lead SWC are softer lead (to allow forming) than cast bullets. FMJ bullets will not expand to any extent, offer good accuracy and reliability, but are expensive (and while are mandated for military applications, may not really be the most cost effective bullet for your purposes). Ranier plated bullets feed like FMJ, dont lead the barrel, and cost 2/3 to 1/2 of FMJ. 230 gr RN feed perfectly in my XD-45 (3000 rnds - no FTFs). Cast bullets cost only what you pay for scrap lead (free to $1.50/lb) 100s of millions have been shot and are ideal for the .45 acp. I cast now, only because the Ranier TMJ have gone up in price so much.
