Formally dropped at SHOT...this is the bullet Prime has been loading in their new 130gr 6.5 Creedmoor load, right?

Comparing Sierra's banded G1s with the Berger Hybrid AR spec of .287, it appears these bullets fly identically at 1000 yards.

Anybody by chance know the OAL of the Sierra 130 from pulling a Prime load?

Posted all of this info in the 6.5x47L thread. I have a 1000pc case of them

Hopefully that bc is correct. Appears quite higher than Berger hybrid at .560

Interesting that the BC is so much better than the 130 TMK.
The 130 TMK has been around a while. I bought a bunch of them when they first came out. They are extremely accurate but a pig. Great for shorter distances but dont fly like 130 or 140 Hybrids past 600yds.

The new 130 SMK is a sleaker, longer, skinnier, pointed 130 so the higher BC makes perfect sense. Different bullet design. These have already been well proven in the Prime US made ammo for some time now. Just now being released in bullet form to us reloaders.

I've had a 1000rd box of them for a few months now but with the holidays, the flu and being slammed at work I didnt get a chance to test them till this past week. SD's of 2 and 3 across many charge weights from 37.3gr - 38.1gr Varget in 5x Lapua brass with CCI 450 out of my 26" 6.5x47L Kreiger.

Accuracy was not the right seating depth, as I loaded them at .01 off the lands. I have a good feeling after this OCW they like to jump like every other SMK. Got the OCW re-loaded back up at .02 off lands. Very consistent 4 shots in a hole and 1 shot below the group with every charge weight tells me it doesnt like that seating depth. Still 0.5" groups

Stay tuned but here are the numbers.

37.3gr - 2915 SD4
37.5gr - 2916 SD9
37.7gr - 2940 SD2
37.9gr - 2948 SD3
38.1gr - 2954 SD2

I've got 500 back home and am eager to try them out. I'm hoping i can achieve those velocity numbers that would make it formidable in my 6.5x47L but given the bearing surface and FB i feel like i'll probably be at 2850 or so just like my 130gr Normas and 130gr hybrids. Should've never went with a 23" barrel when i had this rifle built.

Its just starting to get a little pressure. My load will be 37.7gr which is the same for 130 Hybrids...
How do they compare vs the hybrids for you? Does it look like their going to be at a better price point than the hybrids? I couldn't find any except on Sierra's website. Those numbers look good.

Well since I only shot a quick 100yd OCW I dont have any more info to give you. They will certainly be cheaper than bergers... we know they perform, as I said prime has been using them in their 6.5cm ammo for a while.now...

Ill have more data soon

Padom, do you happen to know the length on the new SMK 130GR? Not really wanting to pull one of the new prime bullets apart.

thanks I saw that right after I posted the question.

anyone know when some G7 data will be out for this?
Sierra posted BC was dead on for me @ 900yds. Entered their BC, my velocity and rifle info into JBM and dialed what it said for 900. First round hit on full size steel was dead center. Shot 4 more and recorded a sub 0.5moa group.

that posted BC is G1 and not G7 curve correct?

Where can they be found for less than $.40 per bullet? That's what I'm paying for 130 Berger's.
And the 130 SMK have a higher BC... .560 vs .584.... So if you pay that for your Bergers why wouldnt you pay that for a higher BC bullet? Their BC is dead on too. Ive shot them from 100 to 1000 and first time out at 1000, I put the BC into JBM, my velocity, rifle info and made a first round hit with my 6.5x47L, dead center on 12"x20" steel. I followed up with 4 more shots and shot a sub half moa group first time out at 1000 dead center of the plate. I also was using Bergers for a while but use these now in my 6.5cm AR and 6.5x47L..

Powder Valley has them for $0.38pc, Opticsplanet has them for $0.36pc

Sorry if I missed it, are these particularly jump sensitive?
0.01 off lands they shot 0.5" groups @ 100yd. My seating depth test showed groups got tighter at 0.02 off lands shooting just under 0.5moa @ 1000. But either way, I would say no they are not. Worst they shot was 0.5moa before finding the optimal seating depth....

I’m interested in trying these out if a gas gun. I’m closer to .080” jump with the 130 hybrid. Worth a shot to try out.

Wow really??? 260rem? I can get all the way to lands and still.room in 6.5cm gasser
6.5 CM. Rifle doesn't like KAC mags, so I've been using PMAGs. Also this rifle shot lights out with factory Berger 130 ammo so I didn't bother with doing a ladder test, I just matched the jump of factory ammo. This was a custom chamber and I had it cut longer for factory ELDs originally.

Did you try LaRue and ASC SS mags?? Both allow same as KAC
