RL-22

[sask boy]

Well guys the time has come :shock: I am almost out of IMR4350 and I am going to start to experiment with a new powder in my 270win. and also the 7mm mag.
If anyone has some loads worked up please let me know.
I would like to start this fairly soon.
I will be using 130gr ABs in the 270win and 160 ABs in the 7.
I believe this powder will deliver more efficiency with case capacity.
Thanking everyone in advance.
PS. I would like to leave COAL the same.
Blessings,
Dan

Dan, I had great success with the 7mm Rem mag and 160's. Went to Sierra for a recommended load, and they replied to work up to 65 grains of RL-22, which I did. That is over-max in Nosler's manual, but is published in Sierra's manual. I've found it works fine with Sierra and Nosler bullets - but it is listed as max, so please work up to it.

No problem getting over 3,000 fps, with excellent accuracy using 160's and RL-22 with the 7mm Rem mag.

Regards, Guy

For the .270, I use 61.5 gr. RL-22, an FC case, CCI 200 and a 130 AccuBond. This is right at 3200 fps. With a 130 Ballistic Tip I get the same velocity with a half grain less powder. These loads are near max according to some manuals and over max according to others, so work up carefully.

You very well may find that leaving the COAL where it is will not net you the best accuracy with the AccuBond, but you may get lucky. I had to fiddle quite a bit with the COAL in my .270 to get Accubonds to shoot as well as Ballistic Tips.

RL22 will be a great propellant for your 7RM. There are no guarantees, however, that COAL will be the same for the best accuracy.

60 gr for the 130 gr----270
66 gr with the 160 gr 7mm mag

 

[CatskillCrawler]

59.5gr of RL-22 has worked well for me with 130gr BTs @ 3050fps.

 

[SJB358]

66 grains of RL22 is a sure thing in the 7RM. Matter of fact, I use about the same combo in my 7WSM as well. Works really well.

Also, not the exact same, but RL22 is also king in my 270WSM with 140's and 150's. 150's push about 3130 or so and the accuracy is REALLY good.

I don't think you'll have too much trouble getting a load to work Dan. RL22 is a GREAT powder.

Dan,

RL 22 will serve you well in both.

I won't use the RL powders but Hodgdon's just came out recently with Hybred 100V which is NOT an extreme powder , is resistant to temperature changes and reputedly has higher energy per grain for burning rate than IMR powders. I know in my .257 Roberts, it gives about 100+ fps higher velocity per charge weight than IMR 4350 does with 110 grain bullets.

I think that I may try it in my .270 Winchester when I am done developing loads for my .257 Roberts.

I'm not sure H100V is an extreme powder, it's listed under there spherical powders and doesn't say extreme on the can I have.
I guess I need to contact Hodgdon and find out

It is listed as spherical and not as an extreme powder on their site.

For my 270 win Rl-22 works well with 150 grain bullet.
58.5 gr of 22 with 215 mag primer. It shoots berger and paritions well. from 22 inuch barrel I get 2850 fps.

[SJB358]

That's pretty darned good V.. I wouldn't be against securing a 270 Win either, especially knowing the 150 ALR's are on their way..

 

[Oldtrader3]

Sorry, I fixed it!

 

[sask boy]

OT3 why will you not use RL powders?

Blessings,
Dan

 

[Oldtrader3]

Dan, I won't for a couple of reasons:
Firstly, they have had Quality Engineering issues with not controlling lot burning rates, particularly with magnum rate slow powders over the years (RL22 and 25 particularly). I like being able to buy a (Hodgdon or IMR) powder and having it burn at the same velocities and pressures with each can and lot number that I buy. I only buy two cans at once.

Secondly, they (formerly Hercules) blew up a large section of the Augusta, Georgia powder plant while I was living in Atlanta. The explosion killed several (20, maybe more people?) and the explosion destroyed the plant and parts of the town of Augusta which were adjacent to the plant. Probably, a powder plant back that era should not have been close to homes and a town. However, the whole explosion happened because they were not following protocols in manufacturing and the explosion was not following rules, human error, egotisim and taking risks with a process which is inherently dangerous! Some civilians nearby had their homes blown up as well as they blew up about (4) city blocks. The powders that they made back then were nitroclycerin based and dangerous to make and they ignored the rules.

Hercules also blew up part of their Utah Plant while I was living in Salt Lake. Again it was not handling dangerous volitile rocket fuel chemicals the way they should be handled coupled with ego and human error. After a couple of those, you don't want to give them money anymore.

OT3 are not all 3 of the companies now owned by Hodgdon? I am not trying to argue or anything but I never heard that before.
I never used the powder because in the rifles I looked at they seemed to get fouled real quick.
But in the last few years I have seen there was quite a change. I than began to believe that they had cleaned up the manufacturing.
Thank you for the information.

Blessings,
Dan

Gerry, Reloader powders is now owned by Reliant which is a division of ATK. ATK also owns Weaver Scopes and several other brands including Outers. I have no issues with ATK except lot burning rate control.

I still hear complaints every year about lots of RL 22 and 25 which are not consistent and this causes customer load variations. When they finally control this parameters, I will reconsider. Believe me when I say, that I do not lose much by using Hodgdon or IMR Powders. Plus the accuracy in every rifle which I presently own is sub MOA. Rifles that do not meet that standard with some tuning involved, do not stay around long at my house. That accuracy standard excludes the 9.3x74R, which I have not tested yet.

Additionally, I have not had to change a single IMR 4350 load in any rifle in over 48 years due to burning rate changes and that is through three ownership changes of IMR; from Dupont to an Australian company to Hodgdon.

I've not experienced any significant issues with RE22 over the past 20 years or so.... at least not anything out of the ordinary. I've seen differences in lots from all manufacturers over the years, and most recently in a batch of Retumbo that was a little hot.

On the subject of RE22 lot changes, I was checking some loads last week to see if there was any variance in two different lots. I shot one round at 100 and one round at 950 with each lot (the original load lot, and the other two new lots). Both groups looked like they would have looked if I'd have run three of the original lot.... so I'm calling it good.

I've also never seen any temp instability that I'd accredit to either poor powder or standards. Do they vary a bit as the mercury is at extremes? Yes, though I've only seen about +/-30 fps. But, I've yet to see a powder that doesn't swing with the temp.... no matter what the advertising says.

RE22 is a 'go to' powder for me... always has been. It'll run right well in the 7RM and it's redheaded little step-brother the asthmatic beanpole .270. I shoot 63gr of RE22 behind the 162 Amax for right at 3k, and MOA for as far as I can see.

Now that's funny! :grin:
