R-17 or R-25 for .25-06?

Since powder is hard to find in most stores, I picked up a pound of Reloader 17 and Reloader 25. I will be using IMR-4350 as my primary powder but out of the two Reloader brands, does anyone have any experience loading either one, R-17 or R-25 for the .25-06?

Any help would be much appreciated.

re25 is a bit slow for the 2506. re17 is a better match but what ive found with it is it can be a finiky powder. Some guns love it and some hate it and there isnt much inbetween with it.

If the R-25 is too slow, is that dangerous or it just won't be as efficient?

The burning rate of RL-25 (RE-25) is slightly slower than Retumbo. Moving up the chart from there is approximately IMR-7828, RL-22, H-4831, then RL-19 being the fastest of these.. RL-25 should not be dangerous but it is at the slower extreme for the 25-06. You may find filling the cases enough for acceptable velocities to be a challenge depending on bullet seating depth. I’v used Retumbo with 120-gr Sierra HPBT’s and will get close to fully compressed loads with a 2.705 oal to ogive. Depends on if the cases are full-length sized or just neck-sized too. RL-17 may just be tooo fast .. always check your handloading manuals and adhere to the guidelines…have fun and be safe!

Hi LLoyd,
rl17 would probably be a good choice in the 25-06 with up to 100 grain pills. My pops is using I 4831 in his 25-06 with 100's and it's been great.

Remington 3.224 CCI 200 Reloder 25 58 3,071

the above is a load from the alliant web site for the 25-06.

I don't have a 25-06 but I've played with both rl22 and rl25 in my 25 wssm. It burns just fine and pushes well, but I couldn't get accuracy with either powder. I was getting speeds I won't publish with rl22 in my wssm; all I'll say is easy extraction and Roy would have been pissed. rl25 was compressed and made 3K fps easily with 120's; this barrel likes light loads though so she was pitching about 2moa with rl25.
I finally settled on 4895(or v550) with 100's and h4350 with 120's. I've recently begun using Superformance, and while a bit finickey, it'll haul well with 3300 fps on tap out of the little wssm with 100's.

I always heard that Retumbo was slower than RL25. I do know that Hodgdon shows Retumbo to be slower, their chart shows RL25 at # 133 & Retumbo at 138.

RL 25 does great in the 3 25-06's I load for, one of the best with heavy bullets (now 2 of those are AI'ed). In the std 25-06 Sendero I get 3,225 with 115gr BT and the Ackley's easily get 3250 plus with the 120 Part. & with great accuracy. I am going to try Retumbo in the Ackley's this spring, I figure on 3275-3300, but we shall see.
