I can't seem to find this info through the search feature ( imagine that?) I am having this 26" 7 Rem Mag made up and was hoping I can reach 3100/160 and 3000/175. If you can link me or publish the QL data I will sing at your funeral for you someday...free! :) Slowest powders I have are R22/7828/H4831/IMR 4831. Although, I did see some R33 online the other day. No joy for H1000 or R25 or N560 for me. Thanks.
 
This will be my first 7mm Rem Mag with a 26" barrel. I've pulled my OCD hair out with 24" models trying to get these velocities in the past, ha. Best I ever got with the 160PT was 2950 and about 2850 with the 175PT, both fully awesome but not what I want! ha I think I will also try that 175 Sierra SBT. Not sure if the 9" twist will do well with the Nosler 175 ABLR just yet.
 
I'll inform my widow to touch base with you. Fortunately, I won't have to be around to hear the presentation.

That 26" barrel does some great things for the 7mm Rem Mag Jim.

Any idea what twist your barrel is?
 
This is a new Remington factory SS take off barrel. We borescoped it and the rifling was very well done. I am assuming it is a 1 in 9", it may be 9 1/4, not sure. What twist does the 175 ABLR require?
 
What does QL say for the 175 Sierra SBT? ( If you answer Dr M I'll do an "encore")

...probably 1:9 1/2; 1/9 1/2...
 
I'm pretty sure it came off of a Mod 700 stainless SPS. I am still thinking 9 1/4"
 
Back in the 80's I got hold of some of the old Barnes 195 sp. ( pure copper/lead core) to try in my 24" BDL 7 Rem Mag. It keyholed them. I was bummed. That was one long bullet too. In fact, from that, I never tried any 160/175 Barnes X/XLC/XBT either in any 7 mag I had. I'm pretty sure a 175 partitionis short enough to get good accuracy in a 9 1/4, just not sure about that super long 175 ABLR ( but it is soooo pretty! ha)

Looks like R33 is the one to give a whirl! I located some, just need my coins to get right now! You're in luck Doc! I know both songs by heart! For myself, I'm partial to "Open my eyes that I may see"! ha
 
I'm partial to the Vhita Vuori powders. They have worked quite well for me. Would love to see some of the new Alliant powders (even the "old" Alliant powders) around here.
 
Be warned that many 7mm Rem Mags will not make the numbers in the reloading manuals. My 7mm Mag is 100+ fps short of predicted muzzle speeds with the 160 Partitions but it still kills game well despite low MV.
 
I hear you OT- I never had a 24" 7 Rem Mag make them either. The 7 STW would, and of course, the 7 RUM did. I'm hoping with a 26" bbl and slow powder I can reach 160/3100 and 175/3000 within acceptable pressure. I just like to see if I can get all the case design calls for. I see no reason to load any magnum below 62000 psi/cup, whatever. I also don't like to run them at 65000 either. I want at least 3-4 loadings per magnum case. More is just icing on the cake, ha. I don't "need to", I just want to see if I can get there with good accuracy. You're right though, I've killed a lot of game with "less than advertised" velocity, but it wasn't because I wasn't trying for more! ha. From what I have read about the new R33 it seems to run at less pressure than even R22. I have to try it!
