I need to find a new powder for my .416 Remington (400 gr Nosler Partition or Trophy Bonded) since AA4064 was recalled due to deterioration problems.

I've got a good stock of RL17 and RL19, but find no data for them, presumably due to being on the slow side. In a faster powder I've got a good supply of IMR4895, but it seems not to give the most optimal velocities. I also have the milsurp version of BL-C2, but have always regarded is as a temperamental powder that might act strangely in a big case.

Would appreciate your experiences, but please don't say "RL15" as I have none of it and don't expect to have any in the foreseeable future.

Varget at the loads in the hornady manual got me to full factory spec, even though I used TSX bullets. As I recall, the Barnes manual was even higher gr than hornady.

I have always used RL15 for my .416 Rem with a 400 grain Hornady bullet and also a 370 Grain Northfork bullet. Good Shooting.

yep .. imho rl15 or slower are way too slow for the 416 rem

varget, benchmark, 748, (or 760/h414), and h335/tac are all great choices

FWIW I could send you quickload. top 10;

I don't have as exhaustive of a list of powders that I've tried compared to Rich, but I've loaded for the .416 Rem. for over 20 years and nothing came even close in accuracy to RL-15 in my rifle.
Most of my experimentation has been with various weights of Barnes bullets and a couple Hornadys.
My only regret is not trying it earlier.

I have found IMR4064 to be a bit better then RL15 in my 416

From the Quickload chart RL17 looks like a possibility. But what does the *T denote?

some of Alliant powders come in 2 flavors Copper reducing and Temperature stable (*T).

for instance old RL15 and new temp stable RL15 sometimes called Rl15.5

PM your email and I'll send the whole chart/list.

I always ran either Win 760 or H4350 in mine, same powders in my 375 Weatherby.
RL15 was far down my list, Varget was another good one in both, and the 458 Lott.

Cheers.

My 416 Ruger loves R17 82 GN behind a 400 GN WOODLEIGH gives a vel of 2400 WITH and ES OF 7
5 SHOTS INTO AN INCH !!

Be a bit careful with the RL15.5 I tested for another forum the same powder charge of Reloader 15 I use in my 450Nitro and it was about 80fps faster. It grouped well buy was crossing a bit.

I've seen many say that slower than RL15 and quickload says it is as well. I have seen 3-4 grains differnce in lots of RL15 over the years to match speed so possibly this lot I am currently using is very slow as well.

Just to clarify, is your rifle chambered in .416 Remington or .416 Ruger?

RL 17 seems fine. From my experience with RL17 in 8x57 Mauser, .375 H&H and .585 Hubel Express, QL shows more velocity (and more pressure) for RL17 than in the real life (chronographed). Maybe, you will find this QL prediction useful.

416 RUGER

Jiri:

Thanks for the Quickload data. It is very close to what I would have guessed for a lightly compressed load of RL17. I might just give that data a try starting just below "near maximum".
