No, well slight typo.

Max load for 2206H in the ADI book is listed as 38gr with 174gr Sie HPBT this is the 6th addition.
for 2206 which is obsolete 37.5 for 174gr.

On ADi's website, ditto.

Yet 38.5 of 2206 is a soft load?

Doesnt look that way to me, now if its 2208, yes OK.

I mean 2208 shows 2506fps v 2446 for 2206H, so really you could look at 40~41gr of 2208 and get the velocity you want at a lower pressure.

Chrony, no, I mean is it calibrated to start with? The point is to look for pressure signs, ie greatly flattened primers, on top of that the 303 case seems to stretch far more on hot loads so staying low points at better case life and receiver life for what is now a 70year old gun.
