RL26 and 300wsm no data?

[DartonJager]

Just today I was gifted a new unopened pound of Alliant RL26 and wish to try it out in my Tikka T3 in 300wsm with 180 grain bullets, but I just left Alliant's reloading page and it has no reloading data what so ever for 300 WSM. Did I miss something at Alliants website? I have read a large number of good reviews of RL26 for use with 300 WSM reloads so there has to be some info out there.

Does anyone know what are the minimum and maximum loadings for RL26 for use with 180 grain copper jacketed lead core bullets? Does anyone know if I simply over looked reloading info at Alliant's WS? I'm a little baffled as to why Alliant would publish a reloading book and include 300wsm in it and not list loads for all powders it makes that are suitable for use reloading it.
Thanks,
DJager/Art

I load the berger 185 with 70.0gr of RL26, getting an average of 3090fps with a 26" barrel. I see a lot of guys around the 68-70gr range with similar grain bullets.

 

[jtmpilot]

This is not exactly what you asked for....but if you should ever decide to consider a heavier bullet, I got this straight from Berger

 

[clark33]

I believe berger also has the data on their website for the 180 Elite Hunter and it shows data for RL26 as well.

Thank you Clark and jtmpilot for sharing your data and for the time it took you to do so. Before I posted this request for help I goggled 300wsm loads with RL26 and found lots of people saying it's a great powder for short mags, not very temp sensitive, but very little actual load data.

I will be making some loads this week and are very interested to see what the RL26 will do.

Thanks again,
DJ/Art.

I have a copy of the Speer manual for 180g bullets. Speer sent It to me last fall. It has 26 and 23 along woth a bunch of others. If you message me your email I'll forward it to you . I'm shooting to 26 in my 300wsm 180hammer Hunter at about 3000fps.

Great load data. Makes me question why I carry around a 30/378 only to get a bit above 200 ft/sec more vel at the cost of 70% more powder and the problems that goes with this.
