In an email sent out early Wednesday, March 27, 2024, Muzzle-loaders.com announced they too had received a shipment of RWS 1075 and 1075+ percussion caps.

At the time of writing, it doesn’t look like Muzzle-Loaders.com has set an order limit, presumably, one could order 1000+ caps for the upcoming competition season if needed.

If you are planning on hunting with a percussion muzzleloader in 2024 and early 2025, I would purchase some caps now to secure your supply for the fall hunting season. Caps have been limited in years past and demand increases as hunters are staring at the calendar waiting for opening day.

Percussion caps are a “Hazardous Material” item and incur an additional “Haz-mat” fee.

What are RWS 1075 Percussion Caps?

Muzzle-Loaders.com have both RWS 1075 and 1075+ percussion caps in stock, which one works with your muzzleloader? Generally, RWS 1075 and 1075+ percussion caps are similar enough in size to fit No. 11 Percussion Caps. If you use CCI or Remington #11 Percussion caps, RWS 1075’s should work fine.

RWS 1075s are usually a little large for #10 Revolver nipples, some shooters have reported that they are able to “pinch” the 1075 cap and get it to stay on the nipple, but the fit is not snug.

How are RWS 1075+ Percussion Caps different from RWS 1075 Percussion Caps?

RWS offers two kinds of percussion caps in the 1075 size class, the standard 1075 and the 1075+ percussion cap. As far as my research shows, the difference between the 1075 and 1075+ is the same difference between a regular #11 cap and a Magnum #11 cap. Just like the magnum #11 caps, the RWS 1075+ is considered to be a “Magnum” primer, offering a slightly hotter burn.

Muzzleloading enthusiasts all have their preference for what cap to use and it’s always good to consult your local muzzleloading club for more insight, but usually, enthusiasts who prefer the 1075+ or magnum caps are using them for hunting and may need the extra power of the +/Magnum cap to ignite a black powder substitute.
