Ballistol Report post Posted April 10 Read up as much as I can on the 7mm Shehane, and would like to ask some questions to people using this cartridge, particularly from a UK perspective. Which bullet is most popular for 1000 yard competitions? Similarly, which powder? As I assume choice will become more restricted going forward. And finally, which brass? Thanks in advance.

Ronin Report post Posted April 10 Berger hybrid 180g H4831sc (for me ) I have a few pounds left Think others have shifted to RS powders Lapua or Norma brass I use 6.5 x284 and go from there I believe Norma mage 284 Specific now Share this post Link to post Share on other sites

Nick 53 Report post Posted April 10 Hi although I don’t shoot shehane , I do shoot 7mm. Using Viht 165 with a moderate load. Lapua Scenar L 180g and Lapua brass necked up from 6.5x 284 to 7mm. Share this post Link to post Share on other sites
No i deer Report post Posted April 10 Maybe o should try the Shehane next time and I will have more room for the powder I put in.i tried H4831sc in my 284 and it was slower than I wanted.think it was near max and 2740fps with a 180gr hybrid rings a bell.they were accurate but not anymore than N165 that is faster and took it over 2800fps.

Elwood Report post Posted April 10 180 grain Hybrid or VLD and I'm afraid 4831 sc is the go to powder. If I do another Shehane I will probably go the 7mm walker or KPR route. Both are effectively a Ackley improved Shehane, you're firing forming anyway, so why not get that extra bit of case capacity that will let you use N165 and get velocities equal or above the standard Shehane.

No i deer Report post Posted April 10 Never heard of the other 2 shehane variations. H4831sc is on the reach hit list grrrrrr Share this post Link to post Share on other sites
No i deer Report post Posted April 11 Would I be right in saying the H4831sc is probaly the go to powder for most of the 7mms Share this post Link to post Share on other sites
Ronin Report post Posted April 11 Shot against Mik Mak at Bisley at the first of the f class league shoots who was using the 284 KMR (mine is a shehane) The KMR had a slight velocity advantage Yes, I believe that short cut is still the go to powder Share this post Link to post Share on other sites
Elwood Report post Posted April 11 My feeling is that 4831sc is best suited to the .284 and Shehane, above that with the magnums my first powder choice would be N165, if that didn't work I would then look at 4831sc. I know a few people using RS70 and doing well with it, I'm not sure about what sort of velocities they are achieving. Share this post Link to post Share on other sites
No i deer Report post Posted April 11 Rutland12 said his 7mm saum was pushing the hybrid 3070fps on RS70 but was temperature sensitive at what temp it spikes around didn't say.i have got half a tub of both H4831sc and H4831.enough to do several coarses of fire.shoot a few test groups then load them up just to use it up.
