[4fifty8]

• new from Ruger features 16.6" barrel https://www.ruger.com/products/HawkeyeHunter/specSheets/67107.html
• looks rather cool with aftermarket muzzle brake
• Hornady .358 Win brass / BR-2 / A2015 / Re15 / 2400 reduced load
• Hornady 250gr SP / Woodleigh 310gr / CamPro 38 Super 180gr plated
• no recommendations - near max loads - safe in my rifle ONLY
• compared to my 20" barrel BLR muzzle speed loss about 60 fps about what I expected
• typical LC6 trigger breaks clean with creepy heavy pull weight 5~6 lbs easily improved then should group tighter but ain't too bad as is
• 310gr @ 2025 fps mv for hunting

Leupold FX-II 4x33mm for hunting

Nikon 3-9x42mm for plinking with CamPro 180gr

• possible to make .358 Win brass from .308 Win. I just run it thru my .358 Win FL resizing die works for me
• Speer Reloading Manual No.12 says when using reformed .308 brass to reduce starting loads by 5% & work up from there

For comparison Doubletap makes .358 Win. 310gr Woodleigh Weldcore ammo: https://doubletapammo.com/collections/358-winchester/products/358-win-310-woodleigh-weldcore-20rds

Rated 2075 fps mv (24" barrel) vs. my 310gr carbine load 2025 fps (16.6" barrel) - only 50 fps speed loss with way shorter barrel.

That rifle looks sooo good. Even the brake looks fantastic.

Neck resizing doable with my RCBS FL sizing die screwed out 2 turns & de-primer pin lowered works for me not a recommendation.
