Well seeing how you asked...Mike Willard of SwampFox God rest his soul...
135gr @ 1700 fps (Nosler)
155gr @ 1525 fps (XTP)
180gr @ 1400 fps (XTP)
200gr @ 1240 fps (XTP & FMJ) 9.4 grains LongShot measured by Shadow
200gr @ 1325 fps (XTP & FMJ) 9.9-10.0 grains LongShot FULLY SUPPORTED AFTERMARKET BARREL ONLY
Mike used mostly Hodgdon's LongShot powder and that loading you have you have has see some issues as many were using it.
Use Caution: You will need a gun with great support, and good Recoil springs and even then I could have some issues....
I did a pull down on the 1240 as shown above and another forum member pulled the 1325 load and I had spoke with Mike prior to his passing about theses loads and they are what they are!
I doubt the DT will meet the advertised data...But the SwampFox will be up there.
