The Barnes 225gr XPB was a accuracy favorite of my NULA's previous owner with 4759 and N110. That is what lead me to try the 225gr FTX as an economical option. I have most of his old load data and his target pics. 4759 might have been a better choice since my main reason was "economical" and its cheaper than the N110 im using.
Its my belief that the 225gr FTX is lightly constructed and probably has a fairly soft lead core. I dont have a cross section cut or any measurements to back up this theory but i THINK this might be part of the reason it can be so accurate.
Maybe it obturates easier than a SST or some other FTXs. I know from use with subs the 45-200gr FTX held up far better on media (wet phone books and a water jug combined). The 225gr though basically came apart under the same conditions. Both are made for greatly different FPS ranges, the 460S&W vs the 45 Colt in a lever gun. Thats a big different if you look at the advertised Hornady ammo data for both.
I also noticed with subs i couldnt get the 200gr FTX to shoot as well either but it was still easily good enough for deer hunting accuracy. Im not sure if dimension differences or ogive shape ect were the reasons but it appears to fit the theory. I will need to try some with smokeless next time out and see how they compare.
What i really liked about the trace is the very reasonable peak PSI and curve. I would prefer to keep both in that range with the NULA since its contour is thinner than the Savage barrel. Im guessing the N110/225gr FTX load i shot last time is making a bit more pressure and only yielding a bit more fps if any.
Thank you for your efforts and i will be very interested in the 200gr traces too. It sure helps in keeping it "fun" with a lower "pucker" factor when trying new things.
