Suggest you try a more efficient powder .. like Ramshot Hunter or H-100 V |
Use the 110 with R17.

But, the OP can experiment to his hearts content. But I know where I would start. |
One of the 4350's is what I'd load with a 130 gr bullet.

Unburned powder?

I load for my buddy's 270 with the 130 TSX bullets with a similar load to Chuck's other than it's with the IMR variety of 4831. I can't remember the charge weight off the top of my head, but it chrony's at about 3050 fps out of a 22" Browning A-Bolt.

I’m curious if someone has a newer or newest version of Nosler’s reloading manual that can take a picture of that cartridge and billet page and post it. I don’t have access to one but I’m willing to bet I know what they recommend.

Newest Nosler Data is available on line for almost all cartridges.
270 Win Data. Click the tabs for the different bullet weights. https://load-data.nosler.com/load-data/270-winchester/ |
Here is the actual Barnes load data inc case you are interested.
https://www.barnesbullets.com/wp-con...sterForWeb.pdf I always liked 4831 SSC in the 270 with 130s and that is what we loaded for many years. If we could find 4350 in SSC would have tried that but the 4831 was much easier to come by. Lately we have also been using H 100-V in them and it works great too. Same velocity, lower pressure, low SD and great accuracy. |

I wouldn't use a Barnes bullet to begin with. With a 26" barrel I use IMR4831. With a 22" barrel IMR4350.

“One of the most frequently
encountered misconceptions in handloading is that a charge of smokeless powder is still burning when the bullet (or shot charge) exits the muzzle. As “evidence,” many shooters cite the muzzle flash, especially visible in dim light. Nope, that ain’t burning powder. Instead it’s the hot gas produced by burned powder, re-igniting once it strikes the oxygen in the atmosphere. Instead, almost all smokeless powder burns within a short distance in front of the cartridge. The exact point varies with the powder’s burning rate, the cartridge, the projectile etc. But even in huge “magnum” rifle cartridge, over 99% of the powder is burned burned within 4-5 inches of bullet travel.“ John Barsness |

Upon exiting the muzzle, the unburned hot powder receives a new oxygen source from the atmosphere and completes the burn. As is the case with the 270 /h4831 example, 95 %. of the powder has been consumed just short of 14" in the bore. John Barnsness notwithstanding. |
All the cool kids are using RL 26 now anyway. Efficiency notwithstanding.

Salavee, one question. Have you ever opened a real bottle of RL26 in your life?

And we are talking 270 WIN here. Are you sure those numbers are right? S12 |
57-60 gr of H4831. The end.

It really is that simple. I’ve never met a 270 that didn’t like that combo. But of course I’ve nowh near met them all.
