Alaskapopo Posted September 8, 2015 Share Posted September 8, 2015 Hi a friend recently just gave me a bunch of bullets and some where 220 grain West Coast bullet 10mm plated bullets. Anyone have any data for these int he 40sw loaded long and in the 10 mm? Thanks in advance. Pat Link to comment Share on other sites More sharing options...
usa259 Posted October 2, 2015 Share Posted October 2, 2015 I just noticed when re-ordering xtreme 180s that they also have 200 and 220. Similar question, any experience using these? Link to comment Share on other sites More sharing options...
notfast Posted October 6, 2015 Share Posted October 6, 2015 I received some Extreme 220 GR plated after I had ordered some 200s. I decided to keep them and experiment. I searched the web and found some 220GR LTC-TJ (?) data for WSF on a website called Jeff Maass IPSC load data. I started conservative and developed a 40SW long load that averaged right at major PF with no visible pressure signs. The pistol is a G20 with a LWD 10-40 barrel and a 15lb recoil spring. All listed data uses: (USE AT YOUR OWN RISK) Extreme 220GR RNFP plated bullet. WSF powder at various charge weights. Wolf SPP. OAL of 1.175" 3.6GR of WSF (4 shots NOV 2013) HI 660 LO 605 AVE 631 This load failed to consistently cycle the G20 slide . 3.8GR of WSF (5 shots NOV 2013) HI 719 LO 666 AVE 693 4.0GR of WSF (5 shots NOV 2013) HI 730 LO 699 AVE 715 4.2GR of WSF (10 shots-NOV 2014) HI 744 LO 696 AVE 720 (158PF) 4.4GR WSF (10 shots NOV 2014) HI 775 LO 733 AVE 753 (165PF) I settled on 4.5GR and figured that should consistently be a major PF load. The 4.5GR load was accurate enough for me at 25 yards. I shot the 4.5GR load in some practice matches. Muzzle flip was subdued compared to my normal 165GR major load and the slide felt sluggish. I did not care for the slower slide speed. Some shooters behind me claimed to have seen light reflecting off of the base of the bullet during the night practice match. This was the first time I had noticed a significant difference in slide speed of any pistol I've shot with 'gamer' loads and I found I prefer a lighter bullet with higher slide speed. No load development was completed for a 220GR, 10MM load. Link to comment Share on other sites More sharing options...
mach1soldier Posted October 6, 2015 Share Posted October 6, 2015 (edited) I have experimented with titegroup and 220's quite a bit. These were all .40 loads loaded to 10mm typical lengths.

Tanfomagic Posted August 4, 2019 Share Posted August 4, 2019 I recently got a mould (from Accurate moulds) and casted myself a healthly supply of 40s weighing in at 225ish. Powder coated of course. Loaded at 1.14” coal over 3.75gr of Winchester 244. Mixed brass, Super soft, shot great out of my primary pistol made PF 175ish for IPSC standard but not so much in my spare gun.
