Alliant RL 10x Powder

B

Bench 1

Guest
Does anyone have some laods they could share for RL 10x powder in a 6BR with a 68 gr. bullet. I just bought it and cant find any load data for a 6BR. Thanks
 
If you don't get an answer, PM mark-x on here.

Btw, I looked at Alliant's load data. Find it "out of touch" that they list only 75, 80 and 85 gr bullets for the 6 PPC.
 
bench1 , hotter than N133..I would start at 29.0 gr and work up to 31.0gr. i feel its the max..
I have found a good tune at .010 off touching and 30.5gr of the RL10x in a few different rifles..with a CCI 450 primer..i feel must use the 450.
there may be some truth to it burning dirty but i clean every 15 rounds or so..I have shot 26 rounds just to see how dirty it was and i dont seem to have a problem with it.
now the same rifle i can shoot 31.5gr N133, but trust me 31.0 gr RL10x is HOT.. I have had poor resualts with N135 in both my 6BR's 33.0 grs N135 will stick my bolt. and i have no luck with it shooting consistantly well. But the RL10 and a CCI450 primer just seems to allways shoot well..as time goes on and i learn more,It maybe that the one
6BR i have, had a GREAT barrel on it, smithed by bob White. it has shot so many groups in the low to mid .100's. with RL10 and a 66 fowler, or a 68 gr precision ballistics BT.
you should find the RL10x to shoot well for you..hey report back how it does do..i would be interested ..But for some strange reason i have not been able to get it to shoot as well jamed or with BR4's or fed 205's..i few guys who have reported back..shot it jamed with fed primer...(said it did not do well) Trust me use the CCI450 and .010 off touching..if that shoots well,then you can fine tune it from there.
 
Thanks mark-x that will help for sure. I just got my 2nd 6BR built and got it back last week and have not even broke the barrel in yet. In my old BR I have always shot N135 with BR4 primers with 68gr. berger touching and it has shot a few groups in the high 1's. But usally it puts them in the mid 2's to low 3's. I bought the RL10 and some N133 to try with a Barts ultra 68 in the new gun. I will pick up some CCI450 primers to try. I will give a report on how it does thanks alot.
 
On using RL-10X, in the last 8-10 years (RL-10X came out in 2002 or there abouts) I have shot probably 30-35 or so pounds of it both in the 6PPC and my two 40 degree shoulder variants. It appears very dirty. It will coat the bore with a layer of the decopperant Alliant chose to put in it. Looking in with a borescope it looks awful but it will not hurt accuracy. Do not try to keep a barrel squeaky clean while shooting it as you will spend more time cleaning than shooting.

The main problem I have with RL-10X is that it is hard on barrels. It will shorten the effective life of a barrel by 200 rounds or more-fact!!. I have created shorter lived barrels of probably 12-15 barrels since 2002. It shoots great and you can get some 3500+ fps velocities out of a 6PPC with it but it seems to shoot best in the 3350-3380 fps range with 66-68 grain bullets.

Edit- you will not need CCI450 primers with either RL-10X or V133 unless you get up in the 70,000+ pressure range. 600 yard shooters use CCI450's almost exclusively in the 6BR but they are shooting 90-108 grain bullets in 8 twist barrels with loads like 30 grains varget.

Jerry , not that i would disbelieve you..my 6BR that has ate RL10 since it was new. lost its accuracry at @1,300 rounds and fought it to shoot to 1,600 rounds. And at 1,600 rounds the throat is fire crakced fairley bad..if i scrub it real good it will shoot the first 6 to 7 rounds down the same hole. then its fouled and throws shots out to 1/2 inch still good enough for varmint hunting. I dont shoot the 450 primers because of hot loads,i shoot them because they are more consistant in the 6BR for accuracry..at least they are for me..my load cci 450, 30.5 RL10 behind a 66 fowler chrony at 3,515-3,530 FPS..its were it shoots at..and it ate 1,300 before the accuracry fell off..maybe i just had a great barrel..the throat has hardley moved out at all,just all fire cracked. I have shot the N133 31.5 grs chroney at 3,550 FPS and the accuracry falls of at 3,550 FPS.
It seems if i stay between 3,450 FPS to 3,530 FPS its good above that it goes away..I have pushed it to 3,650 FPS at 3/4 moa..(yuck)..so im working with another new barrel and it has shot the same load good but not great and its been too cold to try and tune anything..I have never shot it in the 6ppc but i might try it..

And I've never shot RL-10X in a 6BR since all my 6BR shooting is with 90-105 VLD's and at 600 yards. My question about your 6BR barrel life is will it shoot in the low 2's and big 1's for 5-shot groups after it has had some 600-700 rounds down the tube?

I guess it all boils down to what you consider accuracy.
 
jerry i was chaseing the tune at 1,300 rounds , shot this in practice.
100yrd targets , shot one fouler round,then the 4 shot group, then the 5 shot group.( after the first 4 shots i made a adjustment to my scope)
two 200 yrd targets from a club group match,,with 1,300 rounds down it...trust me the shots out are do to wind.
I dont know how to hold off, i held the same spot for all shots..we had very switchy winds, head,tail,angle,cross..Ah i just shoot.
with a RBRP..trying to shoot fast.lol ..
knowing what i know now,its kind of a shame i wasted that barrel,playing,testing messing around wondering.ect..
two new barrels, one went back and one is looking promising.but i dont think its going to shoot like this one did..live&learn..

Are the R10X issues still persisting with the formulation change a couple years back ? I'm talking about the stuff with the red star.

They did, Jackie. I'm still shooting some of the 2002 stuff. I had sold a few cases of the original stuff to one of your Texicans and he and I traded. I had a bunch of 8208 he wanted, so we just traded back. I did get a case of Jameson 12 year old to boot!! The crud left in the barrel by the first lot never did effect accuracy anyhoo!!
 
Jerry, that original lot of 10X seemed a little temperature sensitive. When they had the 100-200-300 yard match down at Dublin, Jeff Summers spent one afternoon working up a load. Had it shooting pretty good. This was over the Labor Day weekend, and in Georgia, Labor Day is usually pretty hot.

But the next day, match 1 relay 1, was cool & drizzly. Jeff went out and shot real big. His next step was to unload all the rounds he'd loaded with 10X -- using that then-new Hood device -- and go back to 133. And he began shooting like Jeff Summers again...

Don't know if subsequent lots showed that phenomena, but if I use 10X -- I still have about 7 pounds -- I make sure the whole damn day will be over 80 degrees.

FWIW

Yep, Charles, it ain't perfect...neither is/was T or 133. I can shoot it with less adjustment from early AM to the PM with less grief than 133. Ask Jeff.
Its just something else to do, but remember most of the time I didn't shoot it in the conventional 6PPC.
 
I gave it a run in a 21 inch LV barrel. 29 gns seemed to be a sweet spot with a 67gn BT bullet. Velocity was around 3375 which I checked with two chronographs because it seemed a bit high. Accuracy varied a bit....one day a bow tie, and the next a blow fly. Gave up on it, and yes it was dirty stuff to use..
Cheers, Brendan Atkinson.
