Welcome aboard Joe;

Look Here

I've done more with the 225 FTX than any other bullet I've tried.

Also consider reading This

In my 20" barrel, the best accuracy comes from 38gr Lil Gun, Remington 7 1/2 or WSR primers, seated to just bury the front cannelure around 2.12-2.15 COL and taper crimp to .476 diameter measured as close to the mouth as possible. At half the price of the other FTX bullets, it's not too expensive for practice loads as well.

I tried 38.0 gr Lil"Gun but found 39.0 gave the best groups in my 16" bbl.

Joe-
A couple of questions about potentially important details:

1) What primer did you use?

2) What was your over-all cartridge length?

3) Did you crimp your cartridges? If so, what was the final case-mouth diameter?

4) Did you chronograph your loads? Any data to share?

Thanks, and welcome.

Thanks for the followup up about some details. Let us know what you find for the velocities.

That is consistent with the 7th OBT harmonic for a 16" barrel, assuming the velocity achieved is what QL predicts. I'm very interested in seeing what your chronograph reports. I guessed at 80 degrees F when I modeled your load in QL. Looks like 1 gr of Lil Gun at 80F makes up the difference between a 16" and a 20" barrel in terms of velocity, again depending upon your actual velocity readings.

That is a phenomenal velocity spread for this caliber. Don't change your reloading technique, whatever it is. In all my loading for this caliber, I don't recall ever having gotten an SD of 5. More like 25, though it does not necessarily equate to grouping. Some of my best groups came at SDs of 20-40 with this caliber. I just chalked it up to being what happens to powerful, straight-walled, rimless calibers. When i plugged your particulars into QL, compensated for this caliber, it predicted an average of 2156 fps. I was wrong on the OBT. That prediction was based upon an uncompensated iteration. I'm still learning...

Congrats on the results nonetheless. At 2144 fps, the 225s do this:

The bullet stopped in the 5th jug
