Looking for 270WSM powder recommendations

[westcoasthunter]

I love Retumbo for 140gr and heavier. And rl-23 does food for bullet in the 120-130gr

Im about to start loading for a new 270 WSM (24in tube) that I got up till now this is the first .277 caliber ive ever loaded for.

I have a handful of different bullets that a buddy has given me to try out which includes 129lrx, 140 sierra sbt , 140 interlocks and 150 LR AB.

POWDERS I HAVE AVAILABLE-
R-26
R-23
H/I 4350
H4831SC
7828SSC

So if any 270wsm guys see this and would like to chim in on your experience with these powder combos Id appreciate it.

R-26
7828SSC
H4831SC
R-23
H/I 4350

This is the velocity order I see for the LRX.

For the ABLR:
R-26
7828SSC
R-23
H4831SC

Surprised no one has mentioned MagPro, temp sensitive yes, but accurate with the 150 Berger (3106fps) . H1000 was also accurate at the upper end node (3200+). H4831SC with the 150AB, 140TSX with RL19. Had this rifle for 10 years and these all still shoot great and have taken many animals with it. One of my favorite rifles Nosler 48c in 270WSM 24" barrel.

How many grains of Retumbo are you using and what speeds? I'm testing RL23 and 140gr TGKs in one right now and I'm not having good luck. Single digit sd/es but groups are terrible. I'm going to change the bullet before I try another powder.

 

[Prieto9000]

Barnes LRX 129gr
RL-26 71 gr
CCI 250
Norma case
BTOL: 2.330"
COAL: 2.932"

RE-26 is awesome in mine. Berger 140's and Nosler AB 150's both shoot great

I never could get my 270 WSM to cooperate with 129 LRX's and RL26. Groups were horrible, but yes velocities and SD were good.

This was a ¾-1 moa load on my factory sako finnlight

Right at 2980, 59.9 GR 4350, it will go up over 3000 but this load is 1 ragged hole.

Same here but 58.6 4350 at 3025...very very accurate..I'm at 2400' altitude

IMR 7828 and a 140gr accubonds!!!

 

[EMC2015]

Anyone have some numbers for H1000, Retumbo? I have H4350 I can try as a last resort also but I have faith in RL23. I think the barrel hates that particular bullet.

 

[bigngreen]

Retumbo is my favorite powder for 140gr bullets and up, I ran the 140 Accubonds at 3350 fps, Berger were a little slower with the same load.

 

[Catskills]

RL 26 and 140 accubonds get 1/2" groups at 3,200 fps.

How many grains of Retumbo are you running? Thanks

Great information here, keep it coming. I have been working up 130gr and 150gr bullets myself. Not quite finished yet, once the weather breaks, I'll get back at it.
