Reloader 26

[bowfishn]

sorry my bad federal 215M primers and 210m primers.

I haven't checked how much verticle I have with this scope yet. I am running a 20 moa base. I know I have alot in the reticle push come to shove if I dial back the magnification.

Ok, got it. :cool:

Tried the GM215M primers in my 6.5 Creed using RL26 and HBN coated bullets.
The 130 ELD-M bullets seemed to like the Mag primers, ES dropped into the single digits with good groups at 100.
The 143 ELD-X bullets ES opened up, strange they would shoot several almost ditto on velocity and then one would be 15 - 20 fps up or down. Worked up and down the loads that worked out for the BR2 primers, and tried seating shorter and longer by .010" still the same thing. Groups were between .300" and .470" CTC at 100 yards. Velocities were checked with Magnetospeed Sporter.
My sweet spot with 143 ELD-X was 48 gr of RL26 @ 2990-3000 fps, with HBN coating had to come up .5 gr to match non coated, with mag primers it jumped back up so I reduced .5 gr back to 48 gr to match velocity. Tried from 47 - 48.5 gr at .5 gr jumps always same result with mag primers.
Still too early to make a solid conclusion with my set up but it appears the lighter bullet gets a gain from faster ignition were as the heavier does not need it.
The 130's shoot best at the 3000 fps mark as well and I will be testing the new JLK 130 VLDs with both the BR2s and GM215M primers.
Anyone else try these primers with RL26?

thanks for the update bowfishn! so I take it the br2's are performing better than the 210m's?

are you keeping 3000 ft/sec as you cap or are you running into pressure if you go higher? either way man those are some impressive velocities from such a small case. I need to quit bs'ing and bed my .260 and get out there. the only place I found RE26 got me for $42 after tax for the 1lb. probably the most I've spend on a lb of powder ever!

They are the GM215M that are mag match primers, I haven't been able to find any of the GM210M large rifle match, so I din't know how they will work.
Yes the 3000 fps is where the pressures are peaking at just under max so for the 143 gr bullets that is it, I had shot at 3054 fps with no visible signs of pressure but QL showed it to be at around the 70K mark for that velocity. As was pointed out to me and I believe is correct is visible signs don't show until in the 70K range that is why it is called pressure signs or signs of over pressure. Between the 2990 and 3000 seems to be the sweet spot for my rifle with that bullet as well, if it was above that I would not be able to use the load. I am on my 6th loading with my brass and primers are still tight.
I just got in some of the JLK 130 VLDs I loaded up some with HBN coating 5 each from 47.5 - 49 gr of RL26 BR2 primers and 5 each from 47.5 - 48.5 with GM215M mag primers. Will test them out when I can.
By the way I started weighing the JLKs and after weighing 50 at 130.2 gr and only 2 that weighed 130.1 gr I stopped weighing them and just decided to load them. The loaded bullets all had the same length using the Hornady comparator and weighed out in the groups of 5 there wasn't even a tenth gr difference in the loaded cartridge, I thought that was odd considering all the variables.

Impressive! I missread. I thought you started with 210m's and switched to the 215m's but now I see it was br2 to 215m. I haven't gotten hard core enough to sort bullets or brass yet. but with my goal to reach a mile i'm sure it will be in my future.

Well I tested out the 130 JLK bullets and my barrel doesn't like them. Had a node at 48.5 - 49.4 grains that looked promising, SD went down to 4 fps at 49 gr. with 10 fps SD at each end of the node. The groups were not great .750" to 1" 5 shots at 100, the 49 gr being the smallest group, POI was the same from 48.5 - 49.4 gr. I was .020" off lands so I loaded 5 each at 49 and 48.8 gr at .010" and .030" and tried them to see if they would tighten up, would get 3 to 4 out of the group almost through same hole and then 1 or 2 scattered. 48.2 liked it closer and 49 liked it farther away. I will do one more test .040" from lands and Jamming the lands, we will see. I also shot my 143 ELD-X bullets just to see if they were still good and 5 shots gave me one ragged hole, so I figure it must be It just doesn't like JLKs, I measured the diameter of the JLKs and the Hornadys, the JLKs were .2639" and the Hornadys are .2642" .
It could be I have an oversize bore and the larger diameter bullet shoots better, I questioned that when using H4350 because my loads were much slower than most everyone else that used H4350.
Not slamming JLK bullets they are very consistent in weight and length, but they do not work for what I want.
