Anyone have any good experience with this powder?

I have the opportunity to get 3 lbs. of this powder unopened for a really good deal and have been considering using it in the .25-06 (with 110-120 grain bullets) and in my brother in law's 7mm STW (with 160 grain bullets).

I hear that it is very similar to 7828 only slightly slower.

Any advice is welcome. Thanks -

I'm interested in your results if you give it a try and would be willing to share the info.

I have found Retumbo to be THE powder for the 25-06 at up to 60.5gr.

However RL 25 comes close also.

With 110 up to 120 grain bullets with RL 25 load range should be RL-25 From 44.8 grains to 58.9 grains. Wide range here because can be used with either bullet. i.e. 110gr bullets starting load would be few grains more than 120gr bullets. 25-06 can make pressure quick! If me I would probably start about 50gr with either bullet check speeds to get up to known bullet weight velocities (factory ammo speeds can help). Fed 210 primed.

The 7 STW is nuther animal. With the 160gr bullets RL 25 fits it quite well. RL-25 From 71.0 grains to 79.0 grains. Basically with this combo should be looking for speeds in the low to mid 3,100's. Fed 215 primed.

Hope this helps.
 
I am using it for 110 gr accubonds and if you pass on that deal, I hope you'll share the info because I can use another 3 lbs.

I'm not pushing pressure limits or velocity in my load- but it did better than R22, 7828, imr 7828, imr 4350, r19.

56.9gr, lapua converted 30-06 brass (h2o cap 67.8gr) 3.210 oal, fed 210m
3120 fps, est 44k psi ( low node). AT 30*F - be cautious with this load at temps above 60*.

Bottom shot cold clean bore, 5 shot group. The paper folded into a larger hole in the target where the "5th" shot went through. It's a very soft, more of a push type of shot.

After shooting a few rounds of the 56.9gr this weekend to foul the bore, I can say that R25 is temp sensitive. (reloder 17 is too, in my experience) This spawned my thinking and luckily it was a slow day at work so I got to do some estimates based on cold weather chrono readings (20*F and 70*F) I was able to adjust the load and shoot a group at 80* today, and I believe it supports my theory. My rifle has a node at 1.228- tested with several different powders and bullet combinations. Using this, I adjust for a +/- 2%. I then adjusted QL's BR to match velocity at 80*, adjusted the temp to 70, and created a new powder profile at that temp. dropped it down to 20*, and the BR matched within .0009 of what I had previously. At 80*, it was very close as well. I wanted to see at what temp should I develop the load to give me a wide range over the +/- 2% of the node. I then adjusted the temp to 60* (it will only be shot in warm weather deer/antelope season) and worked out the btimes going down to 30 and up to 100. After a lot of cutting and pasting into excel, a load developed at 60* should cover between 40* and 90* before I see the groups open up outside of the node. Now I am just waiting for the right temp to test my theory. If I shoot below 40, I'll use the 56.9gr load.

I'm going to edit my previous post for safety reasons and will forever list the temperature of which the group/ load was shot in if i am referring to Reloder powders- 56.9 gr at 80* is not accurate.

At 80*, 55.7 gr: (there always has to be that one flier!!!)

200 yards, 3150 fps.

BTW, IMR 4831 was the same between 20* and 80*. Maybe 20 fps different...
 
I'm still trying to make sense of it. I worked on my creedmoor today, finding the same thing- and the R17 profile worked (matches velocity, group size in relation to obt) in both 6.5 and 22-250. Still need to test them at 80*, but 30* to 60* were on.

I'll post some of the temps later tonight.
