I have been experimenting with RL26 under 130 Berger hunters in Lapua brass. After picking a seating depth of 70 thou off the lands, I worked up an OCW series. Once I got that roughed in, I played with seating depth running 10, 40, 70, 100 and 130 thou off. Currently, I am at 40 thou off the lands with 49.9 grains RL26 giving a 3 shot group (I hate those lol) of .612 averaging 3118 fps with an ES of 2. Its only 3 shots so no extreme celebrating lol. Also, one thing on the group, I was pretty jacked up on coffee with my heart banging away. The 3rd shot broke on a heart beat and I pretty much called the flier. I loaded up 5 more to try out tomorrow and we will see how it works. Also, I tried CCI No. 34, Federal 210gmm, 215 and 215gmm primers and there was no real advantage to the magnum primers with the 210gmm being the best for me.

I Adjusted QL for bullet measurements, case capacity, seating depth, etc. and also adjusted the Ba rate to match velocity and it predicts my pressure to be about 61500 psi. Because my rifle is a switch barrel rig, I can not use my Pressure Trace on it. With Lapua brass, I think I am almost close to warm :p lol

I tried to load down to 3000 fps but the accuracy and velocity spread was terrible. Like RL17, it looks like RL26 needs to be at higher pressures to be consistent. One thing I noticed was that at about 3130 to 3140 fps the pressure appeared to really spike sending some bullets well over 3160 fps and having over 60 fps of spread and piercing even magnum and nato spec primers. Recoil was noticeably sharper and there was smoke and sooted necks. I didn't try to keep going to see if things would mellow out for obvious reasons lol.

Overall, I like what is coming together with RL26 and the 130 Bergers. Tuning in the VLD bullets can be funky but once you get it, you are set. I think I am pretty close here. We shall see.

3118 fps with 130's is a rocket, good grief......

yeah it is. Initially it had me worried as to what pressures I was getting. I still really wish I could get my pressure trace on there but the brass looks good, my primers look good, ignition is consistent... yeah. Once I cycle through the brass, I'll start measuring case webs to see where they sit.


I just sent one at a 6" popper I have at 500 yards. Hit about 2ish inches off center at the 7 oclock. I'll take that for now. lol

14" of drift at 500/10mph is some serious juju.

I used Winchester 7mm-08 brass, one pass thru the 260 full length die, and it's good to go....

With Reloader 17...... is the load development method also to 'pierce a Magnum primer... then back off 40-50fps'?

What barrel length are you running Eryhk?

I have to lean on 123s to see 3k.... and I'm not shy about mashing on the pedal and letting the brass decide. But alas, I'm running 20" and 23" barrels respectively. H4350/Varget/4831, RE17/19/22/25, IMR7828, Magpro.... none of them could get me over 2925 with 130 H-VLDs without seeing/feeling some stress in the brass.

Here's a couple more .260 loads that have run well recently....

23" Rock 1-8"....
Remington Brass
140 Amax
fed 210
48.0 IMR 7828 SSC
2800fps

20" Tikka CTR
123 Scenar (or Amax/MatchKing)
Lapua Brass
fed 210
40.5 IMR 4064
2875fps

I have 3 Lbs of Reloader 17, and wondering if it's worth looking at in the 260, opinions? use.....

Definitely worth investigating. Seems to get a little more velocity than H4350 did for me and accuracy was ok too.

I started with Reloder 17 before data was available.
With 130 gr. Berger hunting VLDS I worked up to 45 grs. Very slowly from 42 grs.
This was at an OAL of 2.99" Into the lands just a small amount in my gun.
Nosler load dat shows 45 grs. as max for their 129 gr ABLR at 2.80OAL and their velocity is 3045fpswith 26" barrel.
My 30" krieger beats that by a 100 fps. No pressures signs and accurate. .3-.4'" average at 100 and under an inch off a bipod at 200.
The antelope and hog harvested with it are the only complainers thus far with Reloder 17......

P.s. Its a plains gun so 30" of barrel and 16lbs of weight ain't a problem. Shorter barrels in this caliber I have little experience with.

I don't know anything about 'plains rifles'.....

Here's the only one that ever weighed 16lbs.... and it lasted about a month before I got sick of packing that fhugkin boat anchor.... it was a 22" 6.5x47 that made 2825ish with 130 VLDs , and it was accurate as hell.... but worthless as a 'plains rifle'...

The plains around here ain't that flat, thankfully, but still no trees to clank barrels on. I do not mind the weight or length of my gun for most of my antelope hunting, but I do have a 7 lb. .243 for a stalking/walking gun also.

True. I know several people who are complete and total A-holes to everybody who is not one of their sycophants who are also correct in various analyses they present. When the homunculus from Alaska states things my father told me decades before I readily admit that he knows at least some things.

127 LRX
0.050" jump (OAL is about 2.870")
WW7-08 brass necked down
210m
45.6gr H4350

2920fps from a 22" barreled GAP 260. That velocity is based on come ups out to 700 yards measured at 7500' ASL and has held true up to almost 10,000'ASL and down to 940' ASL.

Hot load so start around 42.0 and work up. No pressure signs in my rifle, but 46.0 did start to show pressure and 46.3 had signs of pressure on most cases.

Anyone try Hodgden Superformance with 130g bullets? Based on the Barnes data posted earlier, it should be great velocity if it's accurate.

Barnes Data with a 120 gr TTSX looks great in the 260 Rem.

They list Superformance powder with a 120 TTSX or TSX :

41.7 gr Min @ 2697 fps and 46.3 c gr @ 2963

c = compressed load
