284 shehane

[EMC]

Hi guys. I would like to know if someone is loading this caliber.
What speeds are you getting with a 28" barrel and 180gr bullets?
Powder i am looking at vihtavuori n165 and n560.
Thank you

I have not tried N-160 yet, but plan to in the future. I use RL-16 & RL-23 topped with Berger 180, 184 or Sierra 183 bullets. The middle node is 2820-2840 fps. There is also a higher node at just over 2,900 fps.
I hope this helps,

Lloyd

Powder i am looking at vihtavuori n165 and n560.

Some of this decision will be based on the supply of any powder you might select for running this cartridge/bullet combination. Bergers are not always available here in the U.S.

I'm guessing that your chosen path is probably F-Class or something similar. Originally, I shot a Shehane but using a 30" barrel. Everyone had jumped on the bandwagon for this cartridge so I didn't see a down side when I built it.

Your choice of powder as stated might come down to the volume of shots and speed of firing.

VVN-165 is a cooler burning powder which always bodes well for barrel life. The single drawback is a slightly lower velocity range.

VVN-560 is a faster (hotter) burning powder and therefore probably will have more of an effect on your throat. You will probably see a gain in the velocity range of maybe 75-100 fps. when compared to the cooler N-165.

As always, I suggest testing both if you have both to see which one favors your chamber and barrel. Your barrel may show a definite preference or not.

I switched to the 7mm SAUM and the Hornady 190 gr. A-Tip bullets. Occasionally we can find a supply of higher grade brass and the A-Tips seem to be consistently in stock.

Enjoy the process!

Thanks guys.
I'm going to start buying components.
It will be difficult to find berger hybrid 180gr

difficult to find berger hybrid 180gr

You can try the Sierra's as well, if you might have better luck finding them.?

Try RL17. With a 28" barrel you'll see close 3000 fps. My straight 284 with a 30" barrel gets to 3K with 180s. No need for the Shehane with RL17. Accuracy is great as well.

I have found in several different cartridges, including the Shehane that RL-17 goes from mild to wild in just a few tenths of a grain. I have used RL-16 and RL-23 with good success in the Shehane and am going to try N-160 when I find the time.
I hope this helps,

H4831sc was always my go to powder, now that I can't get it I use RL26 and 23.
If you're chasing velocity then N165 will be to slow, and although N160 is plentiful I have never used it!

Due to availability issues, h4350 was ok, but I’ve been running h100v with 180 scenars with excellent results so far.

Thanks to all for the help.
I just wanted to know if I can get to the node of 2800-2840fps with vihtavuori n160-165 and a 28" barrel.
I would not like to go below 2800 fps
I would also not want to use double base powder

Cheers

Or perhaps, Lapua 180gn Scenar L's. They run very well.
