Ramshot
Ramshot Grand
A modern magnum rifle powder covering a wide span from the 243 Winchester up to the 338 Lapua Magnum, with the PRC family among its headline cartridges.
The newest Ramshot and the only powder across the Accurate and Ramshot lines that Hodgdon marks temperature stable - which is the reason to look at it. A slow magnum ball for the PRC family, .300 Winchester Magnum and .338 Lapua that is not supposed to drift with the seasons, in a speed band where ball options are scarce. Too new for a real user record, so treat the temperature claim as a claim until your own chronograph agrees.

Grain shape
Spherical with grain density deliberately tuned to magnum case volume, so a full charge fills the case and still meters - the thing extruded powders in the H1000 band cannot do. Thick web sets the burn rate; degressive gas curve as with any ball.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
The only powder in the Accurate or Ramshot lines that Hodgdon's product specifications mark as temperature stable, and it is also flagged as extra clean burning. Manufacturer states the grain density is tuned for magnum case capacity to give good load density. A recent addition to the Ramshot family. Made in the USA.
Burn rate
A slow magnum rifle powder, charted just past Hodgdon H1000 and immediately faster than Ramshot Magnum.
Chart agreement: consistent, but single-publisher - ranked only by Hodgdon (and echoed by the Wolfe/LoadData compilation). No second manufacturer's chart carries it, so the position is uncorroborated. Ranked by: Hodgdon, Wolfe/LoadData.
Powders charted near it — neighbours on the chart are not substitutes, and adjacency tells you nothing about what charge either one takes:
- IMR Enduron 7977 (position 180)
- Alliant Reloder 26 (position 181)
- Hodgdon H1000 (position 182)
- Ramshot Magnum (position 184)
- Norma 217 (position 185)
- Hodgdon Retumbo (position 186)
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 Ramshot'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.
