    Anyone try this combo yet? Looking for info for the 105 Hybrid or new ELD-M bullets in particular.
    has anyone got Quickload data for it? I have 18 pounds of the stuff and need to find ways to burn it up. :D

    shoot4fun,
    We don't have test capability for 6mm Creedmoor, but we did work up loads for 6mm Rem.
    The MAX load for Berger 105gr Hybrid Target loaded to 2.875" COAL was 43.0gr. That load yielded 3070ft/sec from our 24" test barrel using FC brass and Fed210 primer. Please note that load is over the SAAMI max COAL, and the 6mm Rem is a 65,000psi SAAMI MAP cartridge, whereas the 6.5 Creedmoor is 62,000psi MAP (and there isn't a 6CM SAAMI MAP established), so reduce appropriately if you choose to use 6mm Rem data as a comparative starting point.
    Thanks for buying our new powder, and I hope it works well for you.
    Paul

    Thank you for the info but I don't think it prudent to try and extrapolate 6 Creedmoor data from 6MM Rem data. There is a bit of capacity difference and I am not quite sure of the burn rate/pressure curve on RL16 as of yet. If you can give me an idea about those compared to the "standard" of H4350 that would help. I currently load 42 grains H4350 with the 105 Hybrid.
    I do find it strange, seeing as how Hornady has factory ammo for the 6 Creedmoor now, that no SAAMI MAP for it. While I can see not needing it before bringing out brass I just don't see how they can bring an ammo product to market without the "insurance" of SAAMI's blessing.
    Again, thank you for taking time to respond.

    10-4 on the prudent shoot4fun.
    I do see Hornady has ammo on the market, so perhaps they intend on introducing it next month at the January Ammunition Committee meeting.
    Reloder 16 is included in the 2016 Quickload update, so you can go that route if you have the program.
    Regarding the burn rate similarities/differences compared to H4350, I don't think it would be appropriate to compare the two other than in general bulk burn rate terms. The two chemistries are fairly different, and the Bofors TZ process imparts characteristics that make the propellants very efficient. Hopefully Quickload does a good job of providing accurate simulations. We provided Hartmut a tremendous amount of ballistic and thermochemical data, so that should make a good model.
    Good luck,
    Paul

    Reports from testing in a 6.5 Creedmoor/140gr projectiles is that equivalent loads of Rl-16 and H4350 produce nearly the same velocities with the RL-16 getting a slight increase in velocity. I found in my Lapua Palma converted cases, I would have to compress loads of Rl-16 that would have been about 98-99% case fill with H4350 so I stopped development. I am going to try again in a 6mm Creed once it is built. On another point I ordered a 6mm Creed reamer from JGS yesterday and the reamer print they sent me for approval was a copy of the print Hornady sent in to SAAMI for 'certification'. It appears that Hornady is working on a SAAMI standard for the cartridge.

    I use RL17 in 6.5 Creedmoor with 140 Hybrid/142SMK. It gives me more velocity and, in my rifle, better accuracy than H4350. I do use H4350 with 130 VLD for same reasons stated. I am starting load development on a 6.5x47 chambered Bartlein 8.5 twist finished at 30". My hope is the RL16 can push 123-140 class bullets fast and accurate.
    Most assuredly Hornady is working on SAAMI cert for 6 Creedmoor. I spoke to Steve and Jason about that two years ago when I was at the factory.

    I did some testing the other day with RE-16 in the Dasher (105 HVLD) and 6.5x47 (130 Hyb)

    To me, it seems that your favorite load of H4350 and Re-16 will be almost the same. A friend is testing it in both a 6 and 6.5 Creedmoor and has come to the same conclusion with those cartridges.

    6.5 barrel 27" Bartlein
    6mm barrel 26" Shilen

    6.5x47
    40.2 Avg 2944
    40.4 2954
    40.6 2963
    40.8 2976

    Dasher
    34.8 Avg 3014
    35.0 3034
    35.2 3038
    35.4 3056

    Best group on 6.5x47 was 40.6 gr. 3 shots vertical. 1.5 inches @400. I have loads loaded at 40.6 to test seating.
    Best group with Dasher was 35.0 gr. 4 shots 1.0 inch @400.

    Used a 10" drop tube loading each

    shoot4fun and KMart please keep us informed on the rl-16 in the 6.5x47 and Dasher.

    Any new results of tests for the 6 Creedmoor and RL16

    My first match out with the 6.5x47 barrel on my BAT MB was a success. I have test loads with several bullets but didn't really get into the test much before I had to load for the match. I shot 40 gr RL16 (a bit light I think) with 123SMK using CCI 450 primers. The new 8.5 twist Bartlien 5R is cut to 30" and is a .290 neck. It has a .104 freebore so staying with 123/130 gr bulets. Loads chrono'd at 2925 FPS with a 2.6 SD. It was windy during HG but shot well. Our range is limited to 500 yards but we are shooting ten-shot groups in HG. My agg was 2.5" and I know I still need to add powder and refine seating depth.

    RL16 and H4350 have almost identical max loads for the 708, if that would be the case for the 6 Creed RL16 could be an alternative to the 4350 powders, as long as it was accurate of course, ;)

    I shoot a 6x47 Imp. Case capacity is very close to the Creedmoor. I was working with 110 SMK's and RL16 last weekend. Around 39 grains should be a good place to start. With the 47 case I max out at about 44 grains. I don't know if the Creedmoor case is strong enough for that.

    Ive gone as high as 42.5grs 100V with BN coated DTACs, would not go any higher than that, really no need to go that fast, not after speed in my game.

    My accuracy load ended up being 41gr RL 16 with the 110 SMK at 3080. But max is much higher.

    That sounds about right for that powder, if I didn't have any load data for RL16 Id start with 40grs.

    Any target pics you'd like to share? What distance?

    It shoots in the mid .3s at 100. Can't get out to my friends ranch to do any LR load work, the road is too fragile after all the rain we've had. I'll be shooting a 3x1000 F with it Saturday if the weather holds. I'll report back.

    Yea, I like to shoot at 300yds myself, that's as far as our range goes until game day, then it's 600. How far off the lands did you put those 110s? I figured Id start .004" off.

    I have a friend with a ranch I can shoot out to over 1K. I'll have to look when I get back home, but it ended up being farther off than I expected, maybe .015"ish.

    I haven't gotten to testing in my 6 Creedmoor yet for RL16 and I've been using IMR4451 in my 7MM08.
    I did do some 260 loads and going to 44 grains with the 130 Hybrid in Lapua brass was no stretch at all.
