That is just way outside normal velocity. If one of my 6.5's did that, I'd send the chornograph back to the manufacturer to be repaired. More like 6.5-284 territory. Have you shot that at distance to figure drops? Ive never used rl26, so cant coment on your charge.
Kinda reminds me of what was said about the 30-06.
"Remember the Great .30-06 Debate 10 Years Ago?" https://www.snipershide.com/shooting/forum/...e-10-years-ago Verified with MagnetoSpeed
Velocities are the norn with RL26 I am not the only one getting an extra 100 to 150 fps increase using it, you should give it a try.
Berger has RL26 listed for 135 gr classic Hunter. They have 45 gr for start load at 2657 fps and 49.8 gr max load at 2977 fps out of a 24" tube. Their info is almost spot on with QL with RL26 (QL 2972 fps at 57551 psi) as well as info at Alliant shows that QL data on RL26 to be accurate. Based off this I started with 46 gr. with the 140 Nosler RDF and worked up then did the same with Hornady 143 ELDX. Being that one of the weak link in the 6.5 Creedmoor seems to be primer pockets loosening up even with factory loads that have been pressure checked to be below SAAMI Max Pressure I should start to see signs there. QL shows the 49 gr load with 143 ELDX to be 61221 psi, I believe they are close but without Pressure Trace or other pressure testing I can't be sure other than watching for tell tale signs. 48 grains gets just at the 3000 mark with QL pressures of 56490 psi. and that is the spot I am going to work on.
my speeds with H4350 using the MgnetoSpeed where slower than most peoples,Load is with 140 gr Nosler RFD
41 gr. 5 shot average 2674 fps
41.5 gr 5 shot average 2720 fps
42 gr 5 shot average 2758 fps
42.5 gr 5 shot average 2796 fps
I tested my last 140 RDF several days after the first tests with H4350 and RL26.
My results with 43 gr H4350, BR2 Primers, Nosler Brass, COAL of 2.890", 5 shots averaged 2839 fps group measured .391" ctc at 100 yards
as I said my results with RL26 were as follows
140 gr Nosler RDF
46 5 shot average 2805
46.5 5 shot average 2846
47gr. 5 shot average 2881
47.5gr 5 shot average 2924
48gr 5 shot average 2968
48.5gr 5 shot average 3006
no pressure signs
143 gr ELD-X please note I have edited info bellow to reflect that even though I had no sign of pressure according to speeds I tested with the magnetospeed QL data had to be adjusted to reflect my actual ba in my lot of RL26, the default ba reflected lower speeds and lower pressure.
46gr. 2872 fps average vel. ES 13 SD 6.5
46.5gr 2908 fps average vel. ES 6 SD 3
47gr 2939 fps average vel. ES 10 SD 5.5
47.5gr 2954 fps average vel. ES 11 SD 5.85
48gr 2999 fps average vel. ES 12 SD 6.6 (Highest safe load according to QL)
48.5gr 3029 fps average vel. ES 13 SD 6.65 ( too high of pressure to obtain velocity according to QL my lot of RL26 had higher ba than default)
49gr 3054 fps average vel. ES 19 SD 9.6 * ( too high of pressure to obtain velocity according to QL my lot of RL26 had higher ba than default)
*this load was compressed I had to use a drop tube to get all the powder in.
48grs had best group of .216"ctc 49gr was not too bad at .567"ctc
I need to add that even though initial testing showed no pressure signs the 143 ELD-X 48.5 gr and 49 gr loads were over pressure according to QL based off velocities. I changed the ba in the program for the lot of RL26 I had to reflect actual velocities and have sent a total of 1000 rounds of bullets down the tube.
I have settled on a load with RL26 that gives me 2998 fps with HBN coated 143 ELD-X bullets, I now use HBN on all my bullets in both of my 6.5 Creedmoors the loads that gave best results at the upper node but less than 62K pressure are as follows:
26" Barrel Build Savage long action 1000 rounds to date with no measurable increase in distance to lands with loads at following speeds all with RL26
130 ELD-M 3050 fps
140 ELD-M 2990 fps
147 ELD-M 2930 fps
143 ELD-X 2998 fps
24" Barrel 10BA Stealth 300 rounds to date down this one
130 ELD-M 3030 fps
147 ELD-M 2850 fps
