N 570 or RL33 in 338AI, 28 Nosler, 300 RUM

[CUTTER1]

Any experience with N570 & RL33 in 338AI, 300 RUM or 28 Noslers
Looking for loads in long throated rifles with heavy bullets like 195, 230 and 300 Bergers in the respective calibers

I run rl 33 in my 28 nosler with 195s. I run them at 3100fps with 87.2 grains

Thanks

Try rl33 in your 300 rum. I use it in mine with 230 Berger's @ 3050 FPS. I can push them harder with just as good accuracy to 3150, but don't see the point in being so hard on the equipment. This is all in a 26" barrel and using 215m primers. Not sure what rum you have, so I'd hate to put a charge weight out there. But in my sendero 300 rum I started in the low 90s and worked up until I found pressure. There were two nodes, and I settled on the slower one. The gun shoots less than half moa.

I'm running RL33 in both my 300 RUM and 338AI. Loads are as follows:

300 RUM:
Berger 230 gr OTM
94 gr. RL33
3,085 ave. fps - (milder load, trying to extend barrel life)

338AI:
Berger 300 gr Elite Hunter
104 gr. RL33
2,970 ave. fps

I have a Rem 700 300 rum w/26 in. Barrel . I had 100.0 hrs.

I have a Rem 700 300 rum w/26 in. Barrel. I got 100.0 grs. RL33 with a 200 gr. ELDX at 3150 and no pressure yet. Will try 212 ELDX and 215 Berger next. Still loyal to Retumbo. Finally got some N570. Arrives tomorrow. Haven't got any RL26 to try yet. IMR 8133 not impressive . Worked good with 181 Hammers and H1000 even better.

Agree 8133 doesn't seem to be very consistent in any of the three! Just got N570 yesterday. Have ladder test loads ready for all 3, just waiting on better weather. Thanks for your help!

I have loaded RL33 in 13 different 28 Noslers pushing 195s between 3090-3165fps, and 3 .300RUMs pushing 230s @ 3100ish so far. Exceptional results. Amazing accuracy & great speed. A bit dirty burning, but nothing extreme.

To me RL33 is a cleaner burning in 28 Nosler. It is pretty dirty in 300RUM.

Let us know your results . Thanks !

Let us know your results . Thanks !

I'm almost thinking it might work in 300WM, but this stuff is very bulky.

That's kind of its downfall, faster burning than its supposed to be and very bulky.

Keep using RL33 b/c N570 is so hard to find for those (like me) that love it......in all seriousness, been getting slightly better accuracy at similar speeds with N570, and its ALOT cleaner.

Very good to know. Thanks
