I am wanting to see what you think is the best powder to use.
My buddy wants to load some 180 grain cutting edge Maximus out of a 300 win mag
He’s using Norma brass
Thanks
 
Ive had good luck with H1000 if you have a longer barrel. You'll probably find yourself with a full compressed case with coppers though.
 
I have been really wanting to work up a load for my neighbor's 24" older Tikka T3 with a 1:11 twist. The only powder I had on hand was Ramshot Hunter, using 165gr and 180gr Barnes TTSX BTs. Shot it yesterday at 150 yrds, nice older Zeiss duplex scope on there. The best group I could get was about an inch and 1/2 with the 165gr Barnes using 72grns Hunter. He took an elk with that gun about five years ago out in Colorado at around 330yrds, using a 165gr Barnes, but I don't know the powder/charge. They were loads his guide was using and the guide didn't want to tell him the powder and charge weight. So, I am in the boat where I would like to improve that group, and at greater distances for an Axis deer hunt I will be taking in TX in June of 2026. A long way off, and I will have to do plenty of testing in the heat of the summer, but I would still like to know what is working best for any of you out there. I do have some rounds of RL33 that never really shot very well out of my old 700 Remington 300 Win Mag (nothing seems to shoot great out of that gun)- need to have the barrel bedded-beautiful rifle, but not very accurate as it currently is.

Bottom line- what are your best loads using Barnes TTSX BT's? I am a huge fan of Barnes bullets for everything I hunt. I have used Hammer bullets and Bear Creek Ballistics, and they have shot well, but not any better than the Barnes, and more expensive. Thanks in advance for any info.

Yeah, I have that data-just very little in stock. Found some at Mile High Shooters, but shipping and Hazmat are like $83!!! I'm going to give them and call and see if I can't get a first time discount-they sent me a coupon for 10% off, but it doesn't work for the powder.
 
Have you used retumbo?
Yes, in 300wm with 212s and 215s and in 300 Norma with 230s. It works. Never been notably better than h1000 for me and has been a little less predictable. Because it’s slower burning it wouldn’t be my first choice with 180s but that doesn’t mean it wouldn’t work.
 
It’s a bit off the beaten path, but I’ve had really good luck with Hybrid 100v in 300 win mag and 300wsm. 3030fps with 180sst my 24” tikka 300 win mag, 3030 wsm 180sst 300wsm 22” C6, 2760 212 eldx 300wsm 22” c6. H4831sc is also a great powder for those grain weights
