Yes, but only with 130 and 140-grain bullets, in a Mossberg Patriot rifle, which had a 22" barrel. It worked really well with the 130 Nosler E-Tip, with groups well under an inch at right around 3100 fps. With Nosler 140 AccuBonds it grouped around an inch, at a little over 3000.

Basically RL-16 is about like IMR4350 in burn-rate, but double-based and very temp-resistant, with a decoppering agent. Have had the best luck with it in moderate-capacity 6.5s like the .260 Remington and 6.5 Creedmoor.


After using the 4831s for a half century, I thought I'd try the RL16 as I had a lot of it. It's now my go-to powder for my 270s and the 130TTSX or 129 LRX.......very tight groups ad velocity in 3100s out of my Mountain Ascent.
It's worked very well on a moose, a caribou and a wolf. The LRX sheds it's petals easily at very close ranges but the slug went end to end on a bull caribou.
