![]() Start at low end (3.8-3.9) and work up, with a chrono, and watch your cases for pressure signs. So, if you are new to reloading I'd start with the HP-38. I love Titegroup, but HP-38 can't be beat either, in terms of quality. If you overcharge TG it may not be obvious in the case, since each charge drop is a smaller volume, and pressures in 9mm ramp up quick. HP-38/231 is more forgiving than TG, Titegroup being a faster powder. the 125 gr data B-RAD mentions shows 4.4gr W231 as the max for 124gr lead bullet and 4.8gr as max for a FMJ, and I wouldn't exceed that. (Lots of those are 5" barrels, mind you, which will give slightly faster velocities, so you mind need more in a 4" barrel). For the round nose version of that 124 gr XT bullet, for HP-38 (= Winchester 231.it's the same powder) it's my opinion that you can start at the Berry's data loading and work up.Lots of competitor friends use 4.0-4.2 gr of HP38/231 under a 124 grain plated bullet at various OALs that will vary with the bullet, obviously. IDPA load in a CZ is 3.8 gr TG at 1.050" OAL under the 124 XT HP bullet. I also use the Xtreme RN and HP 124 gr bullets with Titegroup and N320. I keep all plated bullets except the Berry TP at 100k rounds plus of Berrys over the years. The Berry's thick plate (they say) will let it fly at 1500 fps plus, whereas I'd say your average XT bullet will start coming apart well before then. The Berry's hollow base round nose thick plated is a higher end plated bullet that will be more alike than different to the XT RN plated bullet, for loading purposes. What's your shooting goal? Plinking rounds at range or competition or?. ![]()
