Where does Reloder 10X fit on the burning rate chart? I can find Reloder 7, Reloder 11, Reloder 12, 15, etc., etc., but cannot find Reloder 10X on any of the burn rate charts I have. I want to try using this powder in my Savage 12VLP in .204 Ruger caliber. Thanks!

I treat it like a 4895 in my 8x57s and 9.3x62s. I've had excellent results with this powder - I am going to try it in my 6mmBR this weekend. Work up slowly...

Good luck.

RL 10 burns about the same as IMR 3031. It's a little more dense which can be good or bad depending.

In a 219 Improved IMR 3031 gives better results. In the .358 Win with 180 gr and 200 gr bullets RL 10 is excellent.

Savage is right on, with the closeness of 3031. However the RL 10 is just a hair faster, in my experience. It seems to have come out so that their was some Alliant Competition for Hodgdon's Benchmark.

Cheers and Good shooting

With all due respect to my esteemed collegues, I am going to have to disagree on this one. The Sierra manual lists Re7 and IMR3031 right next to other. Presumably Re10X would not have been designed to so closely duplicate Re7. Moreover, there is an obvious gap that exsits between Re7 and Re15; presumably Alliant designed 10x to split the difference.

Regardless of what the book says, I have found that I can run charges noticeably heavier than 3031, at least in the 3-4 or different rounds I have tried it in. I reach signs of max pressure almost exactly at the same charges of IMR4895.

When I first started using 10x, I confess, that I started with 3031 charges. However, I quickly discovered that I could go beyond max 3031 charge weights by as much as 10%. A particularly odd, but attractive, feature I have noticed with 10x is its ability to produce tight groups over a surprisingly wide range of charge weights, particularly in my 9.3x62s.

Anyway, all I can do is report my own expereinces. Good luck.

Anyone tried 10x in the 350 Rem Mag? Might work well with 200g bullets (or less).

Thanks for the quick feedback gentlemen!!! I really appreciate the information. I finally found a Web site with the burn rate listed for Alliant Reloader 10X. The Ramshot Web site also lists Benchmark, and Reloder 10X along with their own Ramshot X-Terminator and Ramshot TAC. These last two are supposed to be real good powders for the Tactical 20.



[edited at 11:34 p.m. to add & again at 11:36 because I left one 9 out of #99 on the H 4895 number ]



The Ramshot burn rate chart lists Alliant Reloader 10X right between Winchester 748 and Hodgdon BL-C(2). Reloder 10X is powder #94 (smaller number being a faster powder), IMR 3031 is #86 and H 4895 is #99, while IMR 4895 is listed as #102. If they are correct, that would make RL 10X slower than IMR 3031, but faster than 4895. How much faster or slower, I have no idea.

I wouldn't listen to that Seafire guy, he doesn't know a thing he is ever talking about. Just ask most of the other guys on this forum anyway.

I hear he thinks Blue Dot is a rifle powder!

This guy doesn't know Diddley Squat.

cheers & good shooting


( I'll have to try some in a 338/06 and see what happens).

Yeah, blue dot in a rifle... that's a good one!

I just had another 338-06 put together - I'm working with the Nosler 180 and the Speer 225. I'm thinking Re15 and CCI200s for starts... what about you - 2400 I suppose.

BTW, I'm putting togther a 6mm Rem, so I think it's about time you got on that 250-3000 project!

9.3:

MY Powder for the 338/06 hands down is H 380.

Back up is IMR 4064. I like the volume of 50 grains because with a 200 grain bullet to a 250 grain bullet, the 50 grains of 4064 gives a MV of 2500 fps. I like that versatility.

H 380 gives me 2650 plus with a 250 grain RN, 2750 to 2800 with a 225 grain bullet and 2950 with a 200 to 210 grain bullet.
Accuracy is fantastic. I use a large rifle primer with it only.

Good luck on your 338/06. As far as a 250 Savage that is on the list. I just missed a Winchester Featherweight ACTION and barrel on one recently, left new in the box from the mid to early 1980s I guess. I either want it in a Featherweight or a Ruger International. I have even thought of Bellying up to the Bar and considering a Kimber Action. So as you can see, the 250 Savage is getting serious Air Time.

Without the benefit of a burning rate hierarchy or a controlled bomb test I estimated the burning rate of RL 10 from the velocities obtained in two dissimilar cartridges. RL 10 seems to provide about the same velocity as IMR 3031 by weight of charge.

I did fire some heavier charges in a M99F chambered for the .358 Win. and the velocities ran so high with the 180 gr bullet over the Oehler 35P that I did not report them. This particular rifle has been fired thousands of times by me over the last forty odd years and has excessive headspace now so I did not want to spring it anymore if thats why it has the headspace.

I am getting 2775 fps with that bullet using RL 10 and that's enough anyway for what I hunt and good bullet action.

I suspected RL 10 was slower than IMR 3031 but to be on the safe side I reported it faster. Until I see some other data supporting that I am staying with it's placement at IMR 3031.

Alliant told a buddy of mine to use H322 data, in his 223, if he couldn't find data for the RX10. He wrote them concerning loads for a 35gr bullet.

Anyone know if RL-10x is temp insensitive like RL-15?

HogWild

I have noticed a slight increase in velocity & a change in POI if the round sits in a hot chamber for a minute or so before it's fired. I would have to say that it's 'slightly' temperature sensitive.

Rick

ifin it's a tad slower than 3031, i would imagine it's closer to benchmark.... but it is as CLEAN as benchmark?

the reason i avoid 3031 anymore is that it's DIRTY
