135 A-Tip 6.5 creedmoor

[bahabill]

Been looking to find load data for the 6.5 cm with 135 A-tip using rl26.
Not really anything out there as far as info. Found some for 135 berger but not feeling safe to go with it .
Need to start ladder test and good starting point.

135 a-tip
Hornady brass
fed 210 primer
Reloder 26

Mostly ruger precision rifle and tikka riffle.
Anything info and experience would be grate Thanks

Slow powder for the cartridge. You'll be fine but it's gonna be a dog even compressed. Get the Quick Load info and you'll see what I'm saying. H4350 has been quite spectacular for myself with BR-2 and 450 primers depending on brass primer size. Slight favorable lean toward the 450 loads.

I would go ahead and use the berger data. Just start low and keep an eye out for pressure signs. I tried rl26 with the 147 eldm. I got great velocity with my 26" barrel. Accuracy was not great though. I've had the best accuracy with imr 4350 and rl16 with my 6.5 creedmoor rifle.

Reloder 26 gives excellent velocities in the creedmoor, have you tried it?

I did though it was in a 22 inch bbl which was slow compared to 4350.

Well loaded up some and will give results so others have a starting point. Based it on Berger and loaded up a 10 load ladder test.

I ran R26 with 140 EH in my 6.5cm and was seeing 2875fps with a 22in tube and was still a little ways out from pressure signs.

Well not bad . Not sure with such a decent 10 shot grouping gonna start exploring the highlighted area I guess . 1.2 inch group throughout the test.

Any pressure signs at the top end? Pretty impressive velocities for a 24in barrel. Decent accuracy for a ladder test as well.

Last 2 just started seeing more flattening of the primers and very little difference on extraction. But not extractor marks.

False. Check quick load you will see for yourself. I actually got up to 3050 FPS with the 153 atip (way over Preasure) but my normal load is 2910 FPS no Pressure.

If you were slower with rl-26 over h4350 then you didn't push rl-26 anywhere near hard enough. In a 22 barrel we get about 2900 with the 140s and rl-26
