Reloader 26 in 6.5 creedmoor

[codyadams]

Glad to see it's not us getting hammered this year.....last year I saw the temp as low as -41 degrees, WITHOUT wind chill, for several nights. Wyoming was a cold b&$ch last year.....hope y'all are stayin warm!!

 

[Bowfishn]

We actually got up to 3 today

Got up to 5 deg today, was out in my Speedo shooting my 6.5 Creedmoor catching rays.

You mean the the 6.5 creed also warms you when you shoot It? It's a miracle cartridge for sure!

There is no end to the miracles brought about by the 6.5 CM

There is no end to the miracles brought about by the 6.5 CM

The first time I ever shot 1k I made a second round hit on a milk jug. Is that because I was shooting a creed? I'd say it must be

Man you guys making me shiver. Its 65 in TX.

Seating depth, case capacity, coated or non coated as well as BA on your lot of powder will change the velocity and pressure.
If velocity is up over 2950 fps than most likely pressures are over as well, if it is close to 2900 - 2930 fps it should be alright. If you are using Lapua brass which has a lower case capacity than pressures will be higher for the same velocity.

If you jam the lands pressure will also go up even though you are using a longer COAL. Start low watch closely for signs including velocity as most times pressure signs will not show up until you get above 70K.

Bowfishn if it isn't any trouble could u do a QL with 143gr eldx, hornady brass, lg mag primer and 24in barrel? Thank you in advance.

 

[Bowfishn]

Bowfishn if it isn't any trouble could u do a QL with 143gr eldx, hornady brass, lg mag primer and 24in barrel? Thank you in advance.

I adjusted the Start Pressure to align with the speed change I had seen when using Mag Primers, remember This is only an estimate watch Velocity closely and use the velocity to correspond to the pressure that goes with it. Start low work up along with velocity watch for other signs of pressure, primers, bolt lift, marks on case head etc. remember if signs of pressure show it is because it is above the limits for that cartridge, do not go higher and back down loads.

I will give you 2 listings 1st with 2.800" COAL and 2nd one with 2.840" COAL (most mag lengths will handle this)

Thanks Bowfishn!!

My last Lot of RL26 had a Burn Rate Factor ba of 0.3569, with that rate it will pressure out in a Lapua case (51.5 gr H2O) with 47.4 gr RL26 (106%) using HBN coated 143 ELD-X bullets using COAL of 2.860" out of a 26" barrel velocity of 2976 fps @ 62,343 psi.
My Nosler cases are 52.7 gr H2O so I can get 48.2 gr RL26 (105%) with everything the same gives me 2987 fps @ 62,358 psi. With my 26" build it is on a Long Action so I can load to 2.890" at about .020" off the lands. It give a max of 2998 fps with 48.6 gr. but longer COAL.
Hornady cases usually have the most case capacity.
There are a lot of thing to factor in and then it is where your accuracy node is.

Bowdishn I need your help again..... I need for you to run some data on QL if you don't mind? Here is what I need: work ups for rl26 and H4350 in 6.5 creedmoor, Hornady brass, BR2 primers and 24in barrel. The bullets are: 140gr Berger VLD's, 135gr Berger classic hunter, 143eldx, 140 sst, 142 SMK. I would greatly appreciate it.... thank u Bowfishn.

Does the use of RL26 in the 6.5 Creedmoor necessitate using large rifle magnum primers or standard primers ?
I see that Peterson Brass Co. produces 6.5 Creedmoor brass in both large primer pocket and small primer pocket configuration . Their website recommends the use of the small primer pocket brass if you expect to run pressure in excess of SAAMI specifications , as the brass will be stronger at the base and web . Will a small rifle primer have sufficient power to reliably ignite and fully burn a full case of RL26 propelling an ELD-M 147 gr. bullet from a 28" barrel ?
All comments are welcome .
Thank you ,

I'm running lg primer with rl 26 in my own rifle. We have 3 shop rifles we are running 142's with 4451 & 4350 with sm primers. I'm going to try 4955 in the 3rd gun this wknd. That will be large primer due to being a slower powder. These are 700's were are demonstrating stock, accurized and blueprinted action with a krieger barrel still deciding if a mpa or MDT(my choice)chassis. The chassis is balance of cost vs performance. Since mdt is the choice for the factory I'm hoping that is the choice the boss makes.
