Win or shehane

[Hillhunter]

Friend of mine wants to build a new rifle in 284 , is there a vast difference in going with the straight 284 vs the shehane? He knows that there will be additional costs with special dies etc for the shehane and he is wondering if the additional cost is worth it . He wants this for f class , he already shoots a 308 in ftr

You may get an additional 100fps with the 180g bullets in the Shehane, but the big plus is longer brass life. In order to get that additional 100fps with the Win, you have to really stand on the brass. If you decide to go with the Win make sure you have the reamer made with a proper length throat to handle the bullet you will be shooting. Some info missing in your post is: what bullet and weight you will be shooting and whether it's going to be a single shot or magazine fed? My vote goes to the Shehane version.

+1 on the bullet weights. My Shehane would shoot the 162 A-Max about 100 fps faster than a 180 VLD. Powder also makes a difference. I've shot a lot of 180 Hybrids from a Shehane with H4350 and it seems to like the same velocity as others get with the straight 284; but people are shooting the Shehane as high as 2975 fps with 180 Hybrids and slower powders like H4831SC or IMR 7828SSC. Mine seemed to like 2900 fps with the slower powders but people do go faster with great accuracy. My barrels are usually 30-31 inch 1:9 twist 5R.

I shoot the Shehane and I'm happy with it.
Here is no extra cost for dies. Whidden Gunworks sells them for same price as the .284 Win.

He doesn't know what the best bullet would be ( will wait for recommendations here ) it will be single shot fed

For F-Class, the 180 Hybrid seems to be the best choice if you can find them. If you can't find them, you might contact Bob Cauterucio (BCB on this forum) and see if he could make up some of his 7mm 177gr VLDs. Very consistent bullets on tough Sierra jackets.

Look at the Shehane reamer print in this cartridge guide:
http://www.accurateshooter.com/cartridge-guides/7mm/#284win

You could do with less free-bore for the 180 Hybrids but this reamer has been great with VLDs and Lapua 6.5X284 brass necked up.

The Shehane reamer I ordered has a .315 neck , no turn is .317 for lapua brass ,If you don't want to turn necks go with .317. My loaded rd is .311.If I remember a none turned loaded rd was .3125. The .225 fb is perfect for the vld's but I think a .200 would be better to shoot both Hybrids and VLD's.
Both my shehane and .284 win shoot well with the rite loads but like others say the shehane is easier on the brass and no more expensive to set up. The fire forming can be done in a match so your not wasting components. I used the COW method before I realized how well the fire forming load shot.
Another + for the Shehane is that there is a ton of info from top notch guy's on this site.

No matter which, pick he bullet and have the reamer cut for it or use a throating operation. That neck is short and you want the junction of the shank and boat tail above the place that the donut forms with the amount of jump that you want to allow for.

Another bullet that you might consider is the Lapua Scenar L.

Great info thanks

fwiw do a search on the forum for shehane free bore spec's

Exactly. Just ordered my 7mm uni-throater to find out GSPV has run them out of stock and I have to wait for 6 weeks. LOL

Check Grizzly. More $, but no wait.
