270 with RL-22

Since all the talk about RL-22 being so accurate. I figured what the hell, I'll try it in my 270 with 150g gamekings. I had already found a load that shot 1.5" at 200 yards for 5 shots with 57.5g h-4831sc with a muzzle velocity of 2920fps in a 22" bbl. I was very happy and thats about the best group I have got with h4831sc out of this rifle with about 30 loads tested. I have never not liked RL-22, I just shyed away from it a couple years ago from the talk of it being temp sensitive, so I switched to hodgon extreme line of powders. I used RL-22 in my first 25-06 and my 300 WM and got excellent groups. So anyways, a lot of people have said to put 58g RL-22 behind a 150g bullet and it should be icing on the cake. Well I loaded up 3 loads last night with 57g, 57.5g, and 58g with Fed 215 mag primer, w-w cases, and OAL of 3.410". Results are as follows at 200 yards.

57g 2" 3 shots
2996fps
2990fps
2991fps

57.5g .563" 3 shots
3020fps
3004fps
2993fps

58g 2" 3 shots
2920fps??
3010fps
3039fps

I would say theres definately a sweet spot at 57.5g. Thats where H-4831sc did the best as well. Anyways, I'll take a .56" 3 shot group at 200 yards with a factory rifle any day of the week! Velocity was also 3010fps for the average, which is 90fps faster then my h-4831sc load. I think I will use RL-22 from now on out of this rifle with these bullets. A 150g gameking at 3010fps is no slouch out of a 270 with a 22" bbl.

Rem Man,

I have nothing but good to say about all the Alliant powders.
RL22 is fantastic in my 280AI with 160 gr AB's and Fed GM215M
primers, shooting in the .2"s if I do my part.
RL19 is great in the 280 Rem w/ 140 gr bullets.

Reloader 22 has given me excellent results with the 270 Weatherby as well. No fouling shot is needed.

Same here :

416 wby
300 RUM with lighter bullets
270 WSM and many others.

Rem Man; Glad to see you are having success with RL22! I have also used it with a lot of success in the 257 BOB, and the 270 Winchester. Good velocities, and great accuracy. My best 270 Powder is still Norma MRP though. 58 grains/140 AB very small groups and excellent velocity. Regards, Eagleye.

Norma MRP is basically the same as RL 22. BTW

RL 25 is the same as MRP-2

Eagleye · Apr 3, 2006

Very similar, but not quite the same. I doubt that you would find a lot of difference in burning rate between the two, but in all lots I have worked with, MRP is denser than RL22, allowing more powder in smallish cases like the 7x57, etc. Regards, Eagleye.
