Rljan,
Hodgdon's is just mouthing the "high pressure .40" warning to you. Have gotten the lecture over the phone from them also.
Been using Titegroup & either WC or Berry's in .40, 9mm, .45 & 10mm since the stuff hit the market.
Don't know about their being "target" loads, if you mean accurate or light loads? The following are very accurate out of an STI Trojan & a Glock 20 with .40 KKM bbl.
Chrono'd at ca. 40 degrees so vel. would be higer at 70, etc.
Loads are to make IDPA Power Factor. Have gone as high as 4.2-4.3 with no problems or loss of accuracy.
4.0 TG, 180 Berry's RNFP @ 1.15" OAL, Avg. 915 fps in 5" STI.
4.0 TG, 180 Berry's RNFP @ 1.15" OAL, Avg. 877 fps in G20.
If you mean a "light" load you can go very light with TG due to it's exc. "position insensitivity". Many of the local IPSC/IDPA guys use TG in 9 & .40. It is accuraate and has very low velocity variation even with mild loads.
Haave run in excess of 10K of TG & Berry's 124 RN thru a Glock at ca. 1,100 fps with exc. accuracy.
