Just got my new 300 PRC and I am curious if anyone has tried US 869 powder for it? I am still going to try it whether anybody has already or not. Any information will help.
Thanks.
Thanks.
I just got a 300 PRC rifle and I'm looking for a powder for heavy bullets (at a time when finding ANY powder is a challenge). I'm trying to resurrect this old thread, because Hodgdon now DOES publish US 869 data for the 230 gr. and 250 gr. A-Tip bullets and, even better, US 869 is the highest velocity powder Hodgdon lists for those bullets ...and by a good margin in the case of the 250 gr. A-Tip! Have a look at either the Hodgdon 2021 Annual Manual or https://www.hodgdonreloading.com/reloading-data-centerhodgdon lists no data for this powder in this cartridge and they do have data for 8133 and retumbo, but it seems their silence would further strengthen my suspicion: it's just too slow burning.
I too, am very interested in that powder/bullet combo. I have the components, but unfortunately time is never on my side. I will be testing it before summer is over....hopefully.

As is sometimes the case when Quickload gets it wrong, I would not even consider 869 based on the low velocity Quickload results, but it's hard to ignore the published Hodgdon data.
I'd like to try 869 with EOL 245 gr. Bergers. Any new reports or opinions? Any similar experiences with 869 Quickload runs (far lower velocity than published data)?
Did you ever get a chance to try this? I just got 5# of 869 today. I have a couple hundred 250 gn A-Tips & 100 245 Berger EOLs. Took my 300 PRC to a mile a couple of weeks ago, hoping to stretch it out a little further.I too, am very interested in that powder/bullet combo.

The Hodgdon data says 869 is the velocity king of their powders for 300 PRC heavy bullets so I got some 869 to try too (and also Ramshot LRT and even 8lbs of Shooters World 50 BMG, which won't be the velocity king, according to Quickload).Did you ever get a chance to try this?

I need to trim my 300 PRC brass & then I can start loading for the 250 A-Tips w/ US 869. I'll post when I get some results. Seems like the A-Tips like being seated well off the lands I am planning to start @ .050. Anyone else have seating recommendations?The Hodgdon data says 869 is the velocity king of their powders for 300 PRC heavy bullets so I got some 869 to try too (and also Ramshot LRT and even 8lbs of Shooters World 50 BMG, which won't be the velocity king, according to Quickload).
Unfortunately, I don't have any 300 PRC brass yet. After about 9 months of waiting, my Bergara B14 HMR remains unfired. I got fed up with waiting on Lapua and Creedmoor Sports so I let them cancel my order after the crazy price increase. I have three boxes of new 416 Ruger brass and all the dies I need to form 300 PRC from it but no time to do it. I also have two boxes of Hornady 218 gr. ELD-X ammo, but I'll save it for hunting someday. I recently ordered some RCC brass. After the Lapua price increase, I think the RCC brass might pencil out in the long run, if it holds up to reloading as well as some claim it does. It will be interesting to see how much case capacity is sacrificed though and how often it results in a max velocity reduction penalty.
With 230 grain A-Tips the listed max with US 869 is 88.1C (Hodgdon). I seat out the bullet as long as my magazine allows for cycling. I can get 94 GRAINS of that (US869) in my case (ADG) if I put a finger over the top of case and tap the powder column down to the neck/shoulder junction before seating the bullet. If I do not settle powder enough I get some bulging in the neck/shoulder area. IN MY GUN I get absolutely no pressure signs whatsoever----pockets stay tight, no cratering of primers, no blown primers, no hard bolt lift etc. This is what I do.... follow AT YOUR OWN RISK blah blahJust got my new 300 PRC and I am curious if anyone has tried US 869 powder for it?
