Looking for anyone with experience loading the 26 nosler. Up to 150 rounds on the rifle and it really seems to prefer the 120 E-tips to anything else. Have shot mostly the etips and 127 LRX. I have been getting some good groups and great velocity with Retumbo and CCI 250 primers. Around 3600 with the E-tips out of a 26" barrel. I only intend to hunt with it, and at this time I don't intend to switch bullets or powder

79 gr Retumbo 120 ETips-~-.8MOA 5 shot. Heavy bolt lift
78 gr Retumbo 120 Etips-~1.0MOA 5shot. Heavy bolt lift Avg velocity 3643 SD 12
77 gr Retumbo 120 Etips-~1.0MOA 5shot. Heavy bolt, but noticeably less than previous two. Avg velocity 3601 SD 20. No hangfires or anything suspicious with any of the E-tip loads.
--------------------------------------------------------------------------------
72-75 gr Retumbo 127 LRX ~1.5 MOA 5 shot. No heavy bolts on anything. But, 30-50% of them hangfire.
Both of the above loads had 10 shots of each fired. Both were loaded with the same lot of powder/primer/etc on the same day. Repeated the loads again today with same results. Although I know i could have missed something, I don't think my loading had anything to do with it. Nosler does recommend keeping within 5% of maximum loads due to the cartridges large overbore. I think i may be reaching some critical powder fill percentage in which it starts to hangfire with the reduced charges. I would drop the powder charge down to 75-76gr with the 120 E-tip, but think that i may be right at the point in which the round is just as likely to hangfire vs shoot properly.

So my questions:
1)Any recommended media that could fill up the free case volume, and minimize potential of hangfire with E-tip if i continue to reduce the charge?
2)Anyone have a preferred primer combo with Retumbo in the 26 nosler (I've been told fed 215 which i plan to try).
3)Considering that the bolt lift isn't that heavy with the 77gr charge, shoot again this summer and see how it does. If no issues at 70-80 degrees take it hunting?
 
Are you sure your not jammed into the lands.?you should not have pressure with those loads,also change primers and see if it changes.im shooting 91 grains of 869 with the 127 lrx.might increase your jump to 10 thou and recheck
 
Yes, I'm certain they aren't jammed. Have you shot the 120 E-Tips? I never got any pressure signs with the 127 LRX. I just got misfires when shooting them. What worries me is that with 75 gr retumbo and the 127 I get misfires. With only 2 gr more powder i did not experience any misfires, but feel that I am near an inflection point for free case capacity in which I could start to experience misfires with the 120 gr E-Tip loads if conditions change slightly.

Rnd count:
1-50 factory loads in which I did a barrel break in, at end copper cleaned.
50-70 Barnes 127 LRX handloads hangfires with 72 gr Retumbo (from hodgdon data).
71-90 120 Etip load with 79 gr Retumbo (Nosler data) Heavy bolt, great accuracy.
91-100 130 accubond. 72 gr Retumbo Hangfires.
Cleaned, but no copper cleaning.
101-130 120 Etip load with 77 and 78 gr Retumbo. Good accuracy. Heavby bolt but less so than the 79 gr load.
131-150 127 LRX load with 74-75 gr Retumbo. Hang fires.

Will have to check on the copper fouling. I copper cleaned after break in at 50 rounds until no blue came out with the patches. Even when firing the 120 Etips at round count of 70-90 I had heavy bolt lifts with the 79 gr charge weight of retumbo. Can't imagine that 20 rounds of the LRX from round count of 50-70 would deposit enough copper to jack up the pressure excessively for the Etip loads i fired for rounds 71-90. Will have to try a thorough copper cleaning when i get home next week and see if that does anything. I may just have a tight bore. Also will probably have to try US 869 and see how it does.
 
You are getting better than book velocity I believe with less powder.i will shoot some retumbo threw mine and check results.i also shoot a 6.5 Dakota with 75 grains of retumbo with 140 grain Berger's at 3412fps which is why your pressures seem high.i also had hangfire problems with it till I changed primers,strange feeling when it goes click boom

Thanks. I plan to get some 215s and see how they do. Which primer did you switch to? The nosler data i think was collected with the 120 ballistic tip. It does say to reduce the load for the E-Tip since it is copper. Let me know what velocity you get. I think the barrel is a little fast, but not out of the ballpark of the load data.
 
How is the temp stability on the RL 33? What primer? Thanks.
From what I hear the rl33 isn't that temp stable. I live in Texas and work in Pennsylvania. When I did the ladder test in Pennsylvania, I went to 82ish bf I saw pressure signs. I went with 79 grains to leave me little room for when I get to hotter pressures. I use cci250 on my magnums.
 
P.S., I would try rl33 be 869. I couldn't get the 869 to shoot and I tried several different bullets. It could probably have been just me?!?
 
I have had issues with temp sensitivity of a few Alliant powders especially in larger caliber rifles. How are you liking the retumbo? I can't find us869 locally
 
The retumbo seems to be good with the exception of the issues noted above. There is quite a bit of free case capacity even with 79 grs, which i dont care for. But SD of muzzle velocities were good. I got some RL 33, US 869, and some federal 215 primers to mess with. Hope to get some more data in the next few weeks. I really want to stick with the Retumbo if possible for temp stability. But have to make sure i dont get hang fires with the reduced charges. Will see.
 
I used some rl33(75gr), nosler brass, 140ab...shot 1" at 100..3200fps...3.600"oal...
Not a hot load by any means but shot well..sighted at 200
yards.....
Same day as I was shooting the 7rum(15moa)at a rock at 777 yards the 26 nosler(10.25moa) did well there too...
No problems whatsoever...but will definitely work it a bit more...
77 had barrel jump ejector marks(nonported or breaked)(nosler patriot 48)...
79gr heavy bolt lift....not so tight groups...about 3400fps...beat up brass, loosened pockets...
Stayed at 75 for now...
Bought some 129lrab ammo..supposedly 3400fps...only showed 3300 on my chrony....6000' elevation..maybe 60° temps...
Shot worse than my handloads..2" at 100....
