I've used 60 gr. of RL22 with 150 gr. bullets in my .270 -- a Remington 700 Mountain Rifle -- with very good accuracy at 3000+ f.p.s. muzzle velocity. I used Winchester brass and WLR primers. But this is an exceedingly hot load, and you shouldn't try it unless you work up from below, starting maybe at 54 gr.

I think RL22 is the best powder I've tried in my .270 for 130 to 150 gr. bullets, and that includes IMR and H 4350, and IMR and H 4831.

Thanks for the replies guys! I'll go out and try it.

56-58 grains is max listed in most manuals for 150s. If you have RL-22 lot 25083, it is a "hot" lot and you should reduce loads 2-3 grains from max. There's a warning on Alliant's website about it and it proved true in the 2lbs I have of it.

I have a pair of Pre-64 Mod. 70s in .270, I load 150 Noslers exclusively and use mag primers. I am using 59 grs. in one and 60 grs. in the other, which as a worn throat; these loads have been tested in 90*+ temps. and are fine, but, they are max., IMO. I get 2900+ fps and very good to superb accuracy. Start about 54-55 grs. and work up, this is my favourite load with the .270, after nearly 40 yrs. of shooting it.

I started at 52.0 and finnally settled on 57.0 gr of RL-22

Good luck

I am presently using IMR 4350 behind some 150 grain hornady spitzer bullets in my 270 WCF. I bought a new lot that was not as aerodynamic as the old lot I had that shot very well with the 4350, and this new, blunter lot does not shoot near as well as the other lot, again at least with the 4350. I have a couple pounds of RL22 and was wondering your favorite charge of RL22 with the 150 grain bullets.

Yah Rick,

I am upset they changed it, and you are exactly right about the length. Yes, they are more blunt so I can't seat them out as long, yet they are longer so I have to seat them DEAPER in the case. I was getting .7" 5 shot groups with the old "pointier" or more aerodynamic lot and am just over an inch and can't shrink it with the new stuff. I have an 8 lb keg of H4831SC for my tuned 300 win mag load. I'll have to use some on the .270 as well. So many guys have stated RL22 though I think I will try it first. I need to go home and check the lot number because my powder actually seams to be hotter than older RL22 I bought a few years ago.

I am interested in the "less" aerodynamic profile remark. I also noticed this with the 130 grain bullet. It appears that the new style is somewhat less pointed yet overall length is longer than the older style. I will continue to use H4831 no matter what, 59 grains with the 130 Hornady and 57 with the 150.

I wonder if this change is to make the interlok a deeper penetrating bullet with a thicker jacket, the larger exposed lead point needed to open the thicker jacket. I guess I'll find out this hunting season.
