Home Forums Reloading Big Game Rifles 6.5 Creedmor or 308 Win.?

You'd think huh. I'm running right on the edge of 2700 (2690 fps) in the 26" barrel. Got it fairly zeroed at 100, which is what I like.

Tested in extreme cold, and also hotter temps:


It's a pretty stable load, from the testing I've done. I don't want a 200 yard zero, or some other nonsense like that, because I still shoot a lot at 100 yards.

Yeah I knew there was a pretty short span on the 6cm. I shoot with a guy using a 6GT and it’s pretty sweet. He said he’s had hits at 1 mile with it on a 20-24” plate. I won’t be shooting the 6cm a ton as I’ll have it and my 6.5cm but it will be something to mess with.

Nice. I had the same thoughts with one of my CTR's. I have 2 near identical rifles. One I shoot mainly 140 ELD match bullets in, and the other I shoot 147's in. Like I've told you before, the 147 really shines in the wind buddy. However, I still run 140's in my M&P10 Performance Center, and that rifle just shoots!!! I was hoping to use that in a longrange speed match I did 2 saturdays ago, but the match director said I had to single load it!!!!@@@!!! Ha ha. Well, it's not a true "speed" match then!!! That AR10 would have smoked those targets out to 800 yards.

Something must be off with the setup.

I tried the 147’s from my American Predator and they shot amazing at 100yds but when I went out to 600 they were 12-15” consistently. Another guy I shoot with had similar results with 147’s, maybe we both just got bad batches.


I need to revisit them but I’ve had such good luck with the 140’s I’ve not tried the 147 again.

Interesting thread, I have found the 6 CM does not burn barrels unless you hot rod it keep the fps under 3000 fps and the barrels last surprising long time,I have 1 with over 3500 rounds down the tube and it still shoots lights out. YMMV--- Rio7

I suspect the rate of fire and number of shots in a string are the biggest factor. Powder selection has a role as well in my experience with other cartridges...

I have h4350, h4831 and h1000 to try in my 6cm. I’ve had great luck with h1000 in my 243 so I may try it first.

Sure it is. It gets me out to 1,000. That is all I really care about. Even though it's lacking in other departments. Like RIO said, the 308 is more like a mortar round, than a precision instrument. I'll use what works, and shoot the 308 when it doesn't matter as much. The new saying, "it is what it is", applies.

How much vertical travel does the scope have?

Maybe your rifles just don't like them. They will generally shoot 1" groups at 400. On a very calm day about a month ago, I was running them out to 1,000. Walking it up incrementally, like I do most times. Shot enough at 600 yards with no misses on 10" plate, the same at 700 and 800, so at 900, I got dialed in and rang the 10" steel plate numerous times. When I got to the 1,000 yard plates, I zeroed in on the big plate, and sent 3 to the 10" steel plate. Group looked to be about 3", so I packed up and called it a day. Good enough for the girls I hang out with.

With a 20 moa rail there was only 33 moa of up available from a 100 yard zero?

Am I seeing it right?

Yes, you are seeing that right. Why does it always seem like you and some of the others here are trying to catch me in a lie or something? The rifle is staying just as it is. The way it is set up is fine. This is about cartridges. We all know you love the 308, but indeed it does have its limitations. Whether you want to admit that, that is up to you.

You are also more than welcome to post some pics, and let us know how your beloved 308's do. I'd really welcome that. It may be an eye opener. I've shown some pretty small groups shot at 400 yards on paper and steel, with the 6.5. Show us some of your 308 targets. Thanks!!!

If mine would have shot them like that I’d have a pile of them, lol. My batch and the batch the other guy had trouble with were bought at the same store around the same time, maybe they were weird. I think I remember reading where guys had some trouble with them early on?



Sounds like I need to hunt up another box to test.

The bullet testing can get CRAZY, I have all kinds of 1/2 empty boxes of bullets that just didn't work well for me, now when I find a Bullet and Load that works real well for what I plan on using it for I stop! my curiosity is satisfied. Rio7

Slow down man, you're way off base. I'm simply confused about why with a 20 moa base and a Nightforce scope you can't dial 40 minutes of up from a 100 yard zero. That's it.

I just went to the Nightforce website and looked at several models. Of those I checked the one with the least elevation adjustment range still showed 80 moa. When centered, that's 40 up and 40 down. Combine that with a 20 moa base and now there's 60 up and 20 down. This should allow for finding 100 yard zero and still leave plenty to add the roughly 40 moa to get the 308 out to 1000. Honestly, I'm just trying to understand the situation.

Furthermore, I'm very well aware that 140 grain hybrid target Bergers out of my my 700 5R Milspec in 6.5 drop and drift less than the various 308 loads I shoot.

I picked up a box of those Berger hybrid target bullets at a gunshow here awhile back same as yours care to share what powder you are using?
Merry Christmas too.mb

It's kind of a pisser for sure. When I set it up, I was thinking if it got me out to 1,000 yards, I'd be happy. Maybe the 20 moa rail is not a true 20 moa rail? That is all I can figure. I had to take the first one back, because the packaging said winchester short action, when it was really for a WSM!!! I guess I didn't want to go through the hassle again, since I bought that one in Reno, which is 170 miles from my house. I do know that the scope tracks very well, and is pretty much spot on, as you can see from the tall target test I did last month. Here's the ballistics chart I use, showing it's pretty much spot on with what the calculator says it should be:


In a way, it's not bad if I dial all the way up I know I'm at 1,000 yards. It's like a zero stop for 1,000 yards. Or I can dial 12 or 13, and use the reticle. it's not a big deal, either way.

Merry Christmas!

I've only shot the factory ammo with those.
