Reloader 33 Powder

[Guest]

I see that RL-33 is due out in a few months. Is this powder projected to be viable for the 300 RUM?
If so since RL25 shoots so well with my gun using 200 AB I may give it try.

It should be very close to retumbo. Between RL25 and RL50.

Should work great!

 

[DrMike]

I would be inclined to try it. There is no apparent reason it wouldn't work well in that cartridge.

 

[FOTIS]

I just wish the Reoder series were more temp insensitive.

Looks pretty danged good for the bigger mags. Supposed to be temp insensitive like RL17 isn't it?

 

[JD338]

Scotty,
Yes, it is temp sensitive.

I can't wait to give it a try in the 338 RUM.

I'd be curious if it would give me more velocity than the book max charge I'm using now with RL25 and the 200 AB @3100 fps and similar accuracy. Guess I'll find out later.

JD,
I would assume your 338 RUM would fair well with it.

It should be really good in a 264WM as well I would think. It would be very hard for me to mess with my current load, but I am not sure I could resist. I have had really good luck with the Alliant powders.

My impression of what I heard from the presentation from the Shot Show was that RL33 is suppose to give an extra 100-150 fps over similar powders as well as be temp insensitive

Man, that would put 140's in the 3300 range out of the 264. I imagine it would be a screamer in the RUM's as well..

 

[runtohunt]

Plan to try some 160's and up in the STW when it comes out!

SAME HERE!

Scotty,
I've had equal success with Alliant powders as well. I remember years past I shot my 7 Rem Mag with RL 22 and had excellent results. Time will tell with RL 33. If the track record stays true with Alliant Powders RL 33 should be a great success.
