.270win what powder next?

I have had fantastic luck with H4831SC and 130gr bullets in general. My best performing load is a 130TTSX over 60gr of H4831SC with a CCI 200 primer in Starline brass. I am getting just under 3000fps from a 22” barrel on a Sako A7 and it has consistently shot .75” groups so far.

This load is near max and is a compressed charge. Start low and work your way up.

Well that's what happens when your old and rely on your memory, I looked back in my loading book notes and it was Sept 2004 when I developed that load, I know that was the load I used on my 2005 antelope, my most humble apologies :)
 
Your antelopes a stud. I’ve had great luck with your load and 140 ballistic tips of the newer breed. The original ballistic tips acted like grenades on whitetails if shot 200yards or closer. Huge wound channels and meat waste if shots weren’t perfectly broadside. Jackets are thicker and perform much better now.

Yea he was a knarly old bugger that I chased for 2 1/2 days and finally got him, 272 yards one and done, could have shot others but I liked how unique he was, smith and wesson model 1500, a very long sad story how I ended up with that gun twice and it's still in my safeAntelope-2005-3.JPG
 
I used imr 4064 for many years in my 270, but recently did some testing with Ramshot Hunter and 140gr sst's. Very promising results. I started at 52gr and worked up.

OK, 5 years later, the boy is now a man and I'm building a ladder test with H4831SC and using 130 grain Sierra Gameking bullets. CCi 200 primer. Browning Xbolt 2....Lets gooooooo! I'll report back. Really appreciate all the replies, very happy to have all the information you guys provided. Straight shooting fellas!

Thanks dude, this is helpful!

Good Morning,
I've reloaded for my .270win for 22 years and have always only used IMR4350. I worked up the most accurate recipe for my rifle and have been happily shooting that since. I've dabbled here and there but raising 3 kids didn't leave me with much spare time. This year two of my kids are ready to step up to the big leagues and shoot large rifle. I'm currently working up a load for 110 gr hornady hollow points and it occured to me I should start trying a different powder. I'll be passing this rifle to them soon and for a couple seasons they will probably shoot a smaller weight bullet then the 150gr I've always used.
So, what I'm getting at is, what powder would you .270 win reloaders recommend I try for the lighter weight bullets in the .270win? I've not had great success with 130 gr and IMR4350 so I thought i would try something new to me. Any intel out there would be appreciated. Happy Holidays Folks!
Click to expand...
I've done extensive testing over many years with lots of different powders, and come up with the best (in my view) overall powder for the .270 and that is R-22, for the lighter bullets 1MR 4831 has proven the best in the 110 gr. weight range.
 
Interesting development. Yesterday, I learned that re-using brass from my A-bolt will not chamber in a new X-bolt 2. After some troubleshooting I discovered that new brass fits fine. I am intending to keep the brass separate from here on but I did not see that coming at all...I now have 50 rounds of ladder test for my old rifle, hahahaha.
I'm curious if anyone that sees this has had a similar experience.

The brass shot in different rifles will likely need to be properly fl sized not neck sized unless once fired in the same gun. Partial fl sizing won't work either.

That is the weird part, I did resize them and they don't fit. I rechecked everything with my Dies to make sure they were set up properly. I'm still unclear how it happens, even with the measurements (micrometer) they are within they accepted sizes for 270win.

Oh for sure, chamber dimensions can vary and cause issues using brass in different rifles

For now, I'm going to keep the brass separate for the two rifles. I have some spent casings from the new one now so this week I'll try doing a FL resize and see if they are a problem. Is cleaning out your dies a thing? Maybe that will make a difference? I don't know, the resized brass is the correct size according to my micrometer. Head scratching stuff. Thanks for posting!

Does the press you have a dead stop or does it toggle over? That is important because you might not be setting the shoulder back far enough, to allow for proper chambering if it is a fl die, try setting your die to touch the shell holder then ad a little more and see if that corrects the problem. It could also mean the die your using might have a internal dimensional problem. If the rifles are bolt guns you could purchase a neck size only die, as long as the brass has been fired in the corresponding rifle that would fix the issue, and would probably be a better way to go anyway.

great comment and thank you. I have an RCBS die and one of the first troubleshooting things I did was double check the instructions. (the die has been sitting in my press forever and I can't remember the last time I moved it). The manufacturers recommendation is to bring the shell holder to the top of its throw, screw the die into the press until it touches and then with the shell holder back down, thread it in 1/8 of a turn. I did this, resized the fire brass and it would not fit. I resized, in the same die, an unfired piece of brass and it fits in the chamber.
Older rifle is an A-Bolt 2 and the new rifle is an X-Bolt 2. I'll do my homework on the neck resizing. I'm slightly annoyed because now I'll need to keep the brass separated and use a system to ID the x bolt rounds for when we go hunting.
