IMR Classic
IMR SR 7625
A small-kernel extruded shotshell and handgun powder used for target and light field shotshell loads and standard-pressure handgun loads.
Discontinued sibling to SR 4756, a step faster. It covered light and target shotshell loads and standard-pressure handgun work, and like the rest of the SR family it was well liked and quietly dropped. Nothing current supports it, so use archived manufacturer data or leave it alone.
- 12 gauge target loads
- 20 gauge target loads
- .45 ACP target
- .38 Special

Grain shape
Small-kernel extruded, thinner web than SR 4756: same family, less wall, faster burn. The small grain size means it meters far better than any of IMR's rifle sticks.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Discontinued. Hodgdon no longer lists this powder among current IMR products and it does not appear on Hodgdon's current relative burn rate chart. No manufacturer product page remains.
This powder is obscure enough in the US that its practical character is thinly documented. The note above is deliberately short rather than padded.

Sources
The specifications above come from IMR's own published documentation, linked below. The two “RCM's read” sections are ours, not theirs — our assessment of what this powder is like to load, drawn from its published characteristics and from what handloaders consistently report. No manufacturer endorses them and no source below backs them. If you think we have one wrong, tell us — we would rather fix it.
