I know it defeats the purpose but...

I've been thinking of building a .270 WSM on a standard length action. The whole purpose of the build is to run some Matrix bullets their VLD's show BC in the .73 & .78 with 166 and 175 grains. I just think they would be too long to use in a standard WSM action and would need the extra room to seat the bullets of the standard action. Of course I'd need a faster than 1:10 twist as well to stabalize these bullets.

I know a few guys are running a .270 AM to use this bullet but I think the WSM case. The cheaper supply of WSM brass is a plus IMO. CEB has some mono metal bullets with pretty impressive BC's as well in the .277 bore.

If you look around a bit you'll find the actual BC on them is closer to .65 and .70. I've shot their 210gr VLD's in my .30-8mm. A buddy of mine did some expansion test with them and the results weren't impressive. Most of the bullets never opened and the ones that did blew apart. We shot 2 elk with them last year but I will probably try something else this year or I'll just shoot my Edge with 300gr SMK's.

I'm just thinking LR steel and varmints and the .277 cal just to be different. I like the .270 Win but feel that it would be better in the WSM or larger case with these bullets. BC of .65 & .70 is still pretty darn good, and I figured the BC's might have been a little inflated.

Saw your post on my question on the 6mm on the other forum as well. Probably won't invest in the 117's then. I'll just stick to the Berger and DTAC 115's for my .243 Win. The Berger and DTAC's are a little cheaper as well in the long run.

What about a 270 RUM?
Of course, barrel life would be short.

.270 Weatherby or .270/7mm RemMag?

Or neck down a SAUM case?

The nice thing about 7mm's is the bullet selection. Finding barrels without having to wait 6 months is nice too. That's why I'm doing a 7-300wm and a 6.5-300wm. There is good brass available and it's a easy wildcat to reload for. Hopefully I'll have my reamers next week and I'll be making metal chips in no time.

Absolutely.

If I did not have a 7mm rum I would have gotten a 7mm WSM not a 270 WSM

 

[taylorce1]

Yeah I know 7mm are easier, but I can't get into them. I've tried a few 7's just can't warm up to them. Tried .280 Rem & GNR, 7mm-08, AND 7mm RM. I just like the .270 more it was my first big game rifle.

What is the advantage of 7 -300 WSM when compared with 7WSM. Is it the longer neck? I love the 7 WSM for long range work. With 30 inch barrel, I can push the 180 Berger at over 3,000 fps with lower SD and ES to boot.

 

[IdahoCTD]

DF if your asking me. I wasn't referring to a WSM case. I'm using a 300 Winchester case. I've never had a issue with belted cases and I'm not a huge short mag fan. Plus I think it is about the ideal capacity for good barrel life and velocity. Obviously Gunwerks thinks the capacity is about perfect because they basically duplicated it with their 7LRM case based on the .375 Ruger. Velocity runs 31-3200 with a 180 depending on barrel length. I'm going to try and shoot 162 Amax's as that is what the reamer is throated for. I have no need to shoot 180's as it's primarily a deer hunting rifle and the rounds will work through a standard magazine.

I think it would be pretty cool to have a really sweet LR 270. I know the bullets are a little more limited, but they are fun. I am kinda in the same boat, I have both the 7WSM and 270WSM and "like" the 270 more. No ballistic reason, but I do..

 

[taylorce1]

I'm not looking for a barrel burner so I doubt I'll use a RUM case. I should be able to get 2800 fps with the WSM case and if these bullets are .65-.70 BC then I get some impressive ballistics. Plus at that velocity I should get great barrel life.

I don't know if I'll build it or not, I just don't have anything to do right now. My hunting season is in the crapper, and I don't have any rifles with me right now and no place to shoot within two hours of my apartment if I had something to shoot. So all I have all the time in the world to dream about things.

bigngreen on LRH uses a .270WSM built on a Savage with a long barrel. I'm pretty sure he gets 3050ish fps with the 165's and dang close to 3k with the 175's.

Man, a fast twisted 270WSM would be a fun rifle.. I think Berger has some heavier bullets in the works don't they?

I wished Hornady would make a 150 Amax.. Even their SST has a decent BC..

 

[nvbroncrider]

Neck it down to 6.5 excellent bullets especially for long range.

 

[AzDak42]

This is probably heresy, but I've always thought the .277 and .284 were so damn close together that any distinction between them is trivial in the field. The .284 has a bigger bullet selection so it gets the nod from me.

Berger is making a 170gr that they say will need a 8.5" twist. It would be cool to see Hornady make a Amax as heavy as the can and still use the 10" twist that is common with all the .270 caliber rifles out there. Something in the 155-160gr range.

Those BC's are static BC's, thus they are high, They are low drag bullets but I do not believe the BC's are as good as they actually advertise. I'd go with the WSM myself, those AM's are rough on barrels and a lot more work when it comes to reloading.
