hlpressley Posted June 19, 2016 Share Posted June 19, 2016 Looking for load recommendations for an STI Trojan. I know the gun is capable of better than what I've been able to do so far with my existing load (Xtreme 147 over 3.2 TG 1.15 OAL). Hoping to stay with TG powder and either Xtreme or Blue Bullets. Thanks in advance. Link to comment Share on other sites More sharing options...
L3324temp Posted June 19, 2016 Share Posted June 19, 2016 My favorite load is 3.6g TG under a 135g Berry @ 1.150. Gives me a PF of 132-133 out of a 5" Trojan. Link to comment Share on other sites More sharing options...
Postal Bob Posted June 20, 2016 Share Posted June 20, 2016 I use 3.7 gr titegroup, and a 125 gr Ibejiheads coated bullet at 1.135" oal. Chrono at an average 1085 fps(135 pf). With a 9lb recoil spring, gun remains flat while shooting. Link to comment Share on other sites More sharing options...
motosapiens Posted June 20, 2016 Share Posted June 20, 2016 what's wrong with your existing load? accuracy problem? my STI hates extreme 124gr bullets, i think because of the diameter. It likes coated bullets of .356 diameter, but I think the xtremem 147's are also .356. Link to comment Share on other sites More sharing options...

I've loaded over 100K of the same load on the same machine over the last 5 years and have never had any rounds tumble. But, they seem to do so in the Trojan. They run fine out of my CZ's, Glocks, M&P's etc but for whatever reason the STI doesn't like them. It feeds and shoots them fine but the groups aren't very good and about 1 in 3 will have a slight tumble. I hate to think I can shoot better groups with my carry Glock 19 than I can with this gun. So far, that is the case. Link to comment Share on other sites More sharing options...

So far, that is the case. I didn't get noticeable tumbling, but 1 or 2 out of every 10 round group from my STI would be entirely off the target at 25 yards. Same ammo in my cz carry gun formed a 3-4 inch group shooting offhand. I would try a coated bullet. Switching to leatherhead coated (125 and 147 both) solved my problem, but I bet any brand of coated bullets would work if there is one local to you. I also noted that the 125 grain bullets are measurably more accurate than 147's, but the 147's will still all group in the upper A at 15 yards, which is about as well as i can see to shoot anyway.

hlpressley Posted June 20, 2016 Author Share Posted June 20, 2016 Thanks for the advice. I will try some 147gr Blue Bullets. Link to comment Share on other sites More sharing options...
gregshin Posted June 21, 2016 Share Posted June 21, 2016 Slug your barrel and see what inside diameter of your barrel is. I had 9mm sti that couldn't group nicely...tried all kinds of loads and factory rounds. Took it to the Smith and he measured .357 so no wonder my groups were never good.

So far, that is the case. My CZ's required a 1.10 oal to feed well. My 9mm Trojan likes 1.15. No tumbling. (1911's seem to have a longer chamber....so I'm told) Link to comment Share on other sites More sharing options...
