Thanks Ruger7mm, that's an excellent article to read. For such a superlight hunting rifle that 10 shots group is more than impressive.

Update on the 284 project. Got some 6.5-284 brasses and loaded few rounds for ladder testing. I haven't fireformed them as now powder and brasses are very limited. Both loads are close to the land (haven't measured it yet). Below is the result:
2208 with 139 SST: 1,2 not measured. 3: 47 gr=2858; 47.5=2883; 48.0=2889
Hodgdon Superformance with 162 ELD-M: 53.0 gr=2696; 53.5=2686; 54=2763; 54.5=2767; 55=2817; 55.5=2868
Left is 139 SST, right is ELD-M

forgot to say the barrel is t3x factory, about 21 inches. In its previous life (7mm08) it loves 162 ELD-M and 150 ELD-X. I have loaded few 55gr H-SP and 160 ELD-M for a trip last weekend, and alas, gale force wind! Didn't get the chance to pull the trigger
