Reloder 26

I got the same but quit at 47, lab radar, 26 inc

46.5 shoots great, got some new brass coming will try it. Also imr 4955 shoots great at 2855 is
 
Yes, my results in .243 Win and 6.5x284 are almost ridiculous. There are a few threads about it here and on the hide.

Wedgy; do you mind if I ask what load your using in the 243 and the volocity and group size you get?

Right now I'm using RL 25 in my 243 with 105 berger vld's with good results out of a factory 9 twist barrel. I haven't chronod em yet but I'm happy with accuracy and that they stabilize. And in theory the faster I can push em the better they should be outa my rifle, so I'm interested in the RL 26
 
47.5 grains of RL26 was right around 3400fps from a 7 twist 26" Fed210m 0.020" off
The Federal brass(some scrap that I used for testing) gave 40-50fps more with the same powder charge than the Win brass I ended up using. Held 1.4" at 400 yards without tuning for seating depth, neck tension, etc. but I have kind of switched most of my stuff to lead free so I'm not messing with this load that much. Kind of a shame as that load would smash our smaller coastal deer, but welcome to California;
pay more and get less. Lead free are about $1/ per bullet.
Cutting Edge 100 grain runs about 3150 with 47.5 grains of RL 26. I ran it up to ~3240 and was still safe but wanted to be well below so I can still shoot on those 100F+ days. Keep us posted.
 
I tested out some loads the other day to see what it would do as far as velocity out of my 6.5 Creedmoor 26" barrel. I was using 140 gr nosler rdf with br2 primers, in Nosler brass seated 2.870. I let them get good and hot with my truck running and the heater on so I could get a better idea of pressures in the warmer weather. I would take 5 from the truck put them in my pants pocket and take them one at a time out and shoot them in a warm chamber.
gun)
47gr. 5 shot av 2881
47.5gr 5 shot av 2924
48gr 5 shot av 2968
48.5gr 5 shot av 3006

None of the above showed any sign of pressure problems.
I have some Hornady brass coming in that has more case volume, will try 48 to 49.5 in them.

I was using a Magnetospeed for velocity checks.

What were your groups like? or were you just checking velocity
 
Just checking velocity and what pressure signs were like. I have some Hornady brass coming in I will see how that works with RL26 it has about a grain more case capacity. The Nosler brass is maxed out at 48.5, I will work on load accuracy after without the Magnetospeed attached.

Even with a 26" that sure is speedy. I look forward to trying RL26 in my Wife's RAP.

For a 243? What bullet and bullet weight?
 
Guys

FWIW,
I just finished some more testing in my 284 SP Pistol, 18" bbl length,
using the RL-26 powder and 140 gr Nosler Partition bullets.

My hunting load was running 2850+ fps with decent accuracy,
of less than 2" at 300 yds zero.

I wanted to find the top end load for RL-26 powder with 140 N Part,
and still get decent hunting accuracy at normal hunting ranges etc.

I tested the RL-26 powder with 140 Part up to the max in my SP pistol,
here are the results, stopping at 62.5grs.
Be aware that this load is the MAX in my pistol,
with very lite bolt lift and no marks on the brass etc, use at your own risk.

1st Test,
Loaded overall length of 3.050", throat length of 2.480",
Bullets seated to the base of the neck,
Standard 284 case, custom reamer spec's,
Win 120 standard primers.

Temp was 56*,
Wind at 12 O'clock from the North, at 10-15 mph.

5 shots each test, Win neck sized brass,
Case capacity of 67.9 grs H2o,
All cases weighed within 1/10th gr,

Average Vel = 3143 fps,
High = 3155 fps,
Low = 3124 fps
SD = 12.2

Test #2,
same spec's as above,
Average Vel = 3167 fps,
High = 3189 fps,
Low = 3156 fps,
SD = 14.9

Accuracy was 1.125" at 300 yds for both tests, which I am tickled pink with.
This powder is a lot better than the RL-17, I started with in the 18" bbl.

I thought that the readings were false, as this was a new Magneto V-3 chrono being tested,
so I went home and got my Oelher 33 chrono, reloaded the just fired brass,
and returned to the range and retested the loads again.

Shooting thru/over both chrono's produced a 3-5 fps difference, between the 2 chrono's,
with the RL- 26 loads etc.

I have been using this same powder with 150gr Nosler Partitions in the 7 Mag
with outstanding results also.

Now for some more testing with heavier weight and better BC type bullets,
for longer range s, 1000+ yds ???????

Tia,
Don
 
I haven't tried it yet but these are close to the results I have seen on another forum..sounds like 3000ish with the 160 partitions also. John Barsness said he had similar results out of a 22"barrel. If this is true it will make the wsm much less appealing to many

Not to me !
RL26 gets 150gr VLD to 3350 fps (accuracy load NOT top end) out of a 24" 270WSM.
