What's the BC on those?

I've got some 155-S that. I could try but everyone says. They will not work very well for long range
The ballistics say it will be north of 1350fps at 1000
I don't know but I've seen where a lot of guys say the 155's won't make it at 1000 and be able to hit anything
My best combo
My go to is 175 SMK, 43.5 IMR 4064, 64-67 7.62x51 LC NM brass. Yields 2733 fps and .5 MOA out of both rifles (FN SPR and Savage 10PD). The brass has thicker bases than commercial .308 or newer M80 brass.
What's your barrel length?
How much powder? I've got some jugs I can try
Both rifles are 24 inches. The SPR is 1-12 and the 10PD is 1-10.
I'm running a 1-10 @ 22" . I haven't choreographed em but I doubt I'm much past 2650fps. Need a chrono though to really know
guys following this thread as I am about to upgrade my tikka t3x tac a1…..putting the tikka t3 action in a new chassis and new barrel. Been shooting 175 grn sierras and doing ok. this gun is used for PRS matches only out to 1000k. My barrel options are as such….24” MTU 1:10 rock creek cut rifled or 26” MTU 1:9 rock creek button rifled. Of those two given I will stay with the 175grn and maybe give the 185 jugs a try , which barrel would you suggest?
My vote goes with 24" cut rifle 1-10. It will shoot either bullet just fine. 185 jugg can't be used in tactical division so it would move you to open.
Id go with a 10 twist too
Wow good call on the tactical division limit of 178grn….i missed that.
So losing 2” of barrel not a big issue to any of you? Currently running the factory barrel 24” 1:11 twist and getting 2715 ish with 43.6 of N140 , 175 sierras
obviously with the new barrel i am starting all over again with loads. Going to start with 175 berger OTM & Sierra 175

Std 700 long throat, 208 eld-m's @ 2640 out of 24".
Your full of shit! I'll bet your son shot that with the scope I sold you for him.
Well since that was 2-1/2 years ago, it was definitely me. My little man does well but he isn't able to do that just yet. Which scope is that you're talking about?
169SMK. BC is knocking on the 190gr bullet and you can push it faster than the 190gr type bullets. The 169 is a pointed/tipped bullet from Sierra. They've got the tipping thing figured out. So no need for buying a meplat trimmer etc.. to uniform the tips. It's also got a longer boattail vs the old 168smk. If I recall correctly it's similar to the 175smk. Both of these things really helped the new bullet.
I got a box of 500 of them and they have been awesome to shoot!
I'm going to say you need a 11.5 twist or faster for the 169's. I don't think they will fly good out of a 12 twist barrel. They might and might not. At 2600fps my twist calc gives me 1-12.01 min twist required.

Just busting your chops. Seriously, nice shooting! Never tried the 185's. Only used the 175 SMK and 178 ELD-X. Tried the Warner Tool 160gr but just could not get any accuracy out of them. I think it was a 1-6 USO for your son.
Man I may have to give those a go. I love me some 175smk's in my .308. If it's tipped and will shoot like those then it's gonna be a winner for sure.
Yeah that's it. It's on his .22lr and it's perfect for him. It's a good little scope.
I'm sure that was a 175smk that did that group. Those things shoot great but if these new tipped ones Frank is talking about shoots that well I may switch to those. Tmk just don't shoot as well
The only thing with the closed tipped 169smk is they are longer and more pointy in the ogive area. Kinda like a VLD type bullet. So if you want to seat the bullet closer to the rifling.... you might be seating it further out and or you have more jump.
You won't know till you try them.
My M14 and my 308w bolt guns have a shorter throat than standard 308w so I've got play room.

Have to agree with Frank, using mine out of a 20" barrel on a bolt gun, 1:10 twist with IMR 4046 and they work very well. Haven't tried the Juggernauts yet but mostly because I have about 1,000 of the Sierra 169's. I haven't found a load for those bullets which work for my gas gun 308 with a 16" barrel but haven't spent a lot of time on it either.
Dems deals are on my mind...Hey those 169 SMK shoot bad don't buy them.....
Send me all the bad ones you guys have. I'll load them for blasting ammo!Hey those 169 SMK shoot bad don't buy them.....
