Ramshot
Ramshot LRT
An extreme-range powder designed around the 338 Lapua Magnum with heavy, high-BC bullets, and applicable to overbore magnum hunting cartridges.
About as slow as canister powder gets - a long-range ball for the .338 Lapua with heavy high-BC bullets, the .257 Weatherby and the overbore magnums generally. Ramshot's claim is that it meters more easily than the extruded powders that otherwise own this speed band, which is credible and is the actual reason to consider it. Little user record; this is a specialist's powder and it is priced and stocked like one.

Grain shape
Spherical with a very thick web - that wall is the entire reason it is this slow - and high load density, so it fills an overbore case that would swallow anything faster. It meters where a stick powder of the same speed simply will not.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Manufacturer describes it as one of the slowest spherical powders ever developed and claims easier metering than rival propellants of comparable speed, along with high load density. Made in Belgium.
Burn rate
Near the slow end of the entire chart, between Vihtavuori N568 and N570 — the slowest powder in either the Accurate or Ramshot line.
Chart agreement: consistent across the three charts that list it Ranked by: Hodgdon, Vihtavuori, Wolfe/LoadData.

This powder is obscure enough in the US that its practical character is thinly documented. The note above is deliberately short rather than padded.

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.
