Description
Please Note – All Propellant Powders are in Stock
We can arrange local delivery for customers with mobility / transport issues.
We can no longer courier / post / send shooter’s propellents due to TNT withdrawing that option so these are collect only.
We have to restrict online purchase and only sell face to face on production of a valid FAC, thank you for your understanding.
Designed especially for heavy-duty magnum cartridges, RS80 is our slowest burning powder. It was originally developed for .338 Lapua Mag., but works extremely well even with .50 cal. Browning rounds. Optimized for temperature behaviour, RS80 displays excellent pressure/velocity ratios in numerous calibres.
