Testing RL 26 in the 280 Remington

I'm in development using Re26 to push 150-grain Partitions in my .280. I haven't finalized yet, but the accuracy potential is definitely there, and the velocity potential is almost unbelievable. Whether or not both can be had simultaneously is still in question for me, but I don't see a definite "no" as the answer.

 

[SJB358]

Seems to work really well in a bunch of cartridges. I really like the stuff so far. Seems to be a denser RL25 with some more temp stability. Never had a problem with 25 but 26 is easier to stuff in the cases.

 

[preacher]

Thanks Fotis...I like to see data posted for 22" barrels. Those were good velocities.

 

[FOTIS]

My results from testing RL 26 in the 280 Rem.

I wanted to get an idea of each bullet weight for RL 26

Ruger No 1-A 22" barrel
Norma brass
Rem primer
Temp 60 degrees
Pro Chrono set up at 10' from muzzle

All bullets were .005 off the lands

I fired two shots for each bullet weight.
Two minutes between shots and 5 minutes between each string.

I worked up to these loads, and I consider them a max hunting load for my rifle.
Absolutely no classic pressure signs for any load listed here.

The 175 load/speed is steep and I will reduce it by 0.5 to 1.0 grain.

Everything but the 120's made a nice little same poi cluster.

 

[preacher]

How close do think that 175 data would work with the Sierra 175 SBT? I have a bunch I used in my 7mm Rem Mag and R33. I want to try it in my 280 ( yes I bought another one! A Mod 700 Classic...again) It has a 22" bbl like my old 7mm Express and I can seat the bullet out quite a bit in this Remington throat..

 

[SJB358]

Jim I use the exact same old for the Partitions and Sierra 175. It is always worth backing off but the Sierra has a little less bearing surface than the Partition. Never had a problem out of any of my 7's.

 

[preacher]

Thanks pard...sierra tech told me that even at 2700 I was good on elk to 500. Which is about 150 yds further than I would try w a 280!

 

[hunter24605]

Thanks for this..I'm currently chasing a "favorite" load in my .280..RL 26 is one I haven't thought of trying yet..I have some RL 23 on the bench now, but over on another forum they said it was way to slow for a 280 size case and 140 grain bullets...What say you?

I think a 140 might be on the edge but I would try it. RL26 has amazed me how well it fits in a case that would not even come close to getting RL25 in. I'm using it in quite a few cartridges this year.

If you get that 175 to 2700 in a 280 you'd really have something Jim. A lot of BC on that bullet.

 

[preacher]

What pressure was the 280/R26 175 @ 58.5 to 59.5 showing on QL? I am assuming they were close to 270 Winchester pressure? Thanks.

 

[C.Smith]

I wonder if it is possible to use RL 26 in a 30-06. I know they do not list an data about it.

It might not be optimum, but it can work.

I am seriously considering trying RL 26 in my 280 Rem. What is QL max for that powder behind a 150gr Partition bullet?

[DrMike]

Allowing for a maximum chamber pressure of 64K, velocity could be quite good.

Thanks for this..I'm currently chasing a "favorite" load in my .280..RL 26 is one I haven't thought of trying yet..I have some RL 23 on the bench now, but over on another forum they said it was way to slow for a 280 size case and 140 grain bullets...What say you?

I think a 140 might be on the edge but I would try it. RL26 has amazed me how well it fits in a case that would not even come close to getting RL25 in. I'm using it in quite a few cartridges this year.

So, would this pound of RL-23 I have be better suited in the 150+ grain class of bullets? with Hrndy brass, WLR, 22" barrel?

Thanks for info guys. I just picked up a Remington KS custom shop in 280 and am looking forward to running some 150 BT's through it!

That is a fine rifle and one of the finest cartridges going. The 150 BTs will serve you well.

Went today with my 280 and 154 gr Interbonds...I stopped at 61.5 gr..Didn't see signs of over pressure, except for the primers had a very slight raised ridge around the firing pin dimple..Needless to say, I'm impressed with RL-26.

4 shots at 100 yards.
