I just ran some ladder tests today using a 22" 1:9".

With the 120 grain TTSX and H4350, primer flattening started to show at 42.2, so their data is accurate on that one.

In the 22", all 120 loads tested peaked out at around 2800 and then started showing some primer flattening much beyond that. Tried H414, H4530, and IMR 4831.

Best for the 120 TTSX was 41.8 of H4350, which was just shy 2800 (2795 average), again from a 22" barrel.

42.8 of IMR 4831 was very accurate, but slower at an average of 2700, but it will work well if that is the powder on hand.

I have tried H4831sc with the 120 before, and it was not a good combination, so would not recommend it with the 120.

Worked with the 100 TTSX also. 44.7 of H414 was the tightest load of the day with an average of 3065 fps. H414 could push it much faster, well north of 3100, but the slower load was much tighter, and very mild on the shoulder.

Still need to try H4350 with the 100's.

All loads were with Lapua brass and F210M's.

Take a look at Ramshot Hunter, it's a very good performing powder for me in the 260 Remington. With the 120 TTSX I use 45 gr Hunter. With the 120 gr Nosler Ballistic Tip, I use 48 gr of Ramshot Hunter.

Would if I could find any. Working with what I can find.

Just managed to find a few pounds of H4350 again and thought I'd hit the lotto.

That's pretty good data on the 140s. Some of the rest is lite. I run up to 47gr of H4350 with a 123 Scenar, for example. Have done so in 100+ degree temps and never the first pressure sign (GAP NT). With the 127LRX 45.0-45.3gr of H4350 gives phenomenal accuracy and 2850-2900fps (22" ULA). Thanks for posting. Need to find time to load some 100TTSX for the wife and kids.

Remember that a monolithc bullet builds a lot more pressure than a lead core bullet. therefore the reason for the lighter powder loads in the manual. Barnes bullets are grooved to relieve this pressure. Also keep in mind that due to pressure buildup, seating should move away from the lands rather than closer to the lands

Besides .260 brass; which brass has the least amount of problems resizing to .260; 7mm08 or .308? I am acquiring a .260 and finding 260 brass seems to be a problem unless I buy the expensive brass.

Picked up a 260 3 wks a go, haven't seen any 260 brass or reasonable priced factory loads for it either. Did buy a set of RCBS dies. I pulled 2 boxes of WW once fired 243 Winchester brass off the shelf, lube the case& necks good inside and out and size, you have instant 260's. I'd rather have the right headstamped brass but these will work (and are) until I find some new Remington or drop big bucks for Lapua. I sure didn't have to ream or turn necks either. Magnum Man

jeffbird, I found the exact same max for Superformance with a 127 LRX before they made this available. I used 6.5 Creedmore data and started low for 130 grain bullets in the Hornady Manual. I had the powder and really wanted to give it a try and the case volumes were really close at that bullet weight. Turns out 46.5 gr Superformance with a 127 LRX is right where my Savage model 11 likes to shoot.

My Tikker likes 125 NPTs and H4831. I get 2750fps out of this rather mild load. Works great on game. Will be working up a load for a new Remington 700/8 twist when weather permits.

AR Comp and a 100 grain Partition or Ballistic Tip is a very fast stepping and accurate combination, that I recently enjoyed discovering...

Finally got my tikka 260 together and got to do a little shooting. I started out with some factory nosler with 125gr partitions and was less than impressed I had loaded up some 139gr lapua scenear's and as I worked up the better my groups got I was using 4831SC ended at 45.5 and I'm real happy with the way it was shooting them. They avg right at 2710 should I leave it at that or work up a little more?

Factory lists 42 grains with a 95 grain Bullet...

mine happens to be 43.5 grains...developed that on my own and my Rugers, and Model 70 seem to be just fine with it....

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.

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

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