I've been wanting a 6.5-"something" for a long time and I have decided to go with the wsm. I'm having one built and I would like to hear from some guys who have shot one. How do you like it, what loads do you like for it etc... I've been shooting a 7mm wsm and a 300 wsm a lot lately both factory model 70s that I have accurized and restocked. They shoot great, the 7mm is just over .5 moa at 600yds. Now I've got the bug for something that can really reach out there. This rifle is going to be a complete custom build, Stiller predator action, #5 Brux barrel, Jewel Trigger, Mcmillan A-3 stock. I'm super excited to see what it can do. Brian at Shoot-Long is building it for me.

Using the 7WSM case will give you a tad more powder capacity that a 270WSM. Performance is there but at the cost of barrel throat erosion. The 6.5x284 is bad enough but the 6.5WSM is even shorter accurate bbl life.

I don't get it. A 7 WSM pushing 180 gr Bergers will out reach all of the WSMs. If you want a 6.5, fine, but know that the 7 will out perform it. It's all about BC when you're wanting to go long range, and the bullet I mentioned has a monster BC. It's what I run in my 7 Rem Mag.

Your forgetting the "S" in this whole WSM equation. You can't fit a 180 gr boattailed into a 7mm "S"hort action without having seat it so deep that it loses its its ability to be a magnum round.

I will give you that the barrel life is somewhat shorter on the 6.5, but i dont think the BC argument is a good one. A 140 gr 6.5 vld has a bc of .640, a 168 gr 7mm vld has a bc of .643. Both rounds moving 3000 + fps at the muzzle but the 6.5 is doing it with less powder and a projectile that is 28gr lighter. If 2 rounds are performing basically the same I am going to opt for the one with significantly less recoil. The 180gr 7mm vld has a bc of .684 which is not a huge advantage over the 140gr 6.5. If it's all about BC why aren't we all shooting .338s or .50s?

Then why does my gunsmith bud shoot a 180 out of a WSM? And still "magnum" speed.

I'm not arguing which caliber is better than the other. As I've already stated I own a 7mm that shoots really well. I'm just trying something new. What I'm trying to accomplish with this rifle is good long range performance with less recoil and enough down range energy to be practical for hunting.

Because they cost too much to load/ shoot, and they have significant more recoil. Don't drive a trim nail with a 3 pound sledge, when a 10 ounce will do. Is a 338 LM a badass at 1k? Yep, no doubt. Is a 180 gr 7mm a badass at 1k, yep, no doubt. Is a 338 better at a mile than the 7 is? Yep. I don't have a mile opportunity but a few times a year, and that's why I don't have a 338 LM. If I lived in west Texas, I'd proably have one.

As I mentioned before, if you want a 6.5, great! I have and love my 260, but it won't do what my 7 RM with 180's will do. It also has a longer barrel life, less recoil, and costs a bit less to shoot.

With this argument why don't you shoot a 300 win mag? It'll do everything your beloved 7rm will do with a longer barrel life. I like the idea of a 6.5 wsm. Low recoil and high bc and pretty good velocity. Barrels are consumable. If its used as a hunting rifle the barrel will last a long time. He doesn't want a 260, he wants a 260 with some balls.

I don't have a 300 because the 7mm is the highest BC hunting bullet on the market. I built the 7 to hunt with, not compete with, like my 260. Yes barrels are consumable, but the plan has always been to be conservative with the amount I shoot the 7, because the barrel will probably be done in 1000 rounds. It did an awesome job, ringing steel to 1047 yards in September, it did an awesome job killing an elk in November, it did an awesome job killing whitetails this weekend, and it will do an awesome job on the next hunt I take it on.

I'm not advocating he build a 260, I'm advocating getting better results for what he is wanting the rifle to do. If he "wants" a 6.5mm, fine, but in a WSM the 7mm will provide him with what he wants even more so. If he still wants a 6.5 because he wants more speed, no problem, but he didn't emphasize that on the first post. Now we can move on, since that appears to be the case.

The amount of energy on target at distance will be a lot better with the 7mm WSM over the 6.5 version. I don't particularly believe energy is a sole factor but do believe it plays a good part.

I'm not sure who told you a 7mm has the highest bc hunting bullet. You might want to look at some 230bergers with a bc of .71 or some 300 grain 338s in the .8. If memory serves the 180s in a 7mm are around .648. Don't get me wrong the 7mm is great but its not the end all be all.

Keep us posted on the build. I'm curious if it will match a 264 win mag. I believe it will run very close to it.

No one told me. I have a Berger chart in my shop. It's the highest BC. HUNTING. Bullet on the chart.

Might want to look at the 338 300grain match grade elite hunter with a bc of .818 or the 250 grain at .682. That's off the Berger site. Might want to update your chart.

Maybe so.

I had a LH Rem700 action that used to be a 338 Win Mag to build from. Keeping the bolt and action I did the best that could be done.

O2b are you building it on a long or short action? Do you have to have custom dies or is it possible to use a full length 270wsm die without the expander ball and a neck bushing die? I'm asking because I'm wanting to rebarrel a 300 win mag and this is one of the ideas I've had.

When you're slinging 250 gr of lead does it really matter if it's a "hunting" bullet. Also bullets that big are no fun to shoot at a reasonable speed.

I agree with you, that's why if I ever get my hands on one it will have a good brake on it.

I used a 7rm to make my 257wby on a savage. I did the best I could with it. grin

I'm building on a long action, mainly for stock availability and because if I don't like the 6.5 I will have more options when it comes time to re-barrel. I'm not sure about the other part of your question. I'm trying to figure all of that out myself. I will be using 300wsm brass because I have a lot of it. The guy building my rifle just finished a 6.5wsm for himself and he has developed a load for it that he is happy with. I'm going to copy his load in the beginning and tweak it as needed. I'm a novice reloader so a wildcat like this is going to be good for me. One disappointment is that I wont be able to use my 7mmwsm brass to load for the 6.5.

There's some 325s for that 338 over 1.0 made by RMB. I set a guys 338 RUM up with them.

At what point is BC just high enough. I know the Gunwerks guys like anything over .50 for LR.
