I like more volume in short barrels, 280 AI with Peterson brass is my recommendation.I'm a dirty sl*t for lapua brass and am struggling with analysis paralysis. Bore volume vs short fat powder columns vs no trimming. Have a defiance long action so trying to milk performance. Help.
I think I can fit 3.6 but i'd ned to pull my mag again.30-06, throated for 180HH or even the 166HH that will provide the extra velocity especially with faster powder. I topped 2900fps 180HH with W760 in 22" 700ADL stock rifle for my son and is extremely accurate. Added freebore gives you options. Curious, what is the magazine COAL?
+1 for the 30-06 Serengeti.
Best expansion ratio in a short barrel, best sellection of components, and loaded ammo available in a pinch.
I would consider 30-.284 if hamstrung by magazine length, but no reason to go that route with a true long action.
I installed the SRS TI Pro 3 ST, works real well.I got to just under 2700fps with the 215s out of my 22" '06. Too much of a good thing for me, though - that rifle weighs 7.5lbs all up.
...maybe I'm just 'sensitive'
I would suggest 7mm-08AI or the like.Curious what others will say..... I wanted to build my daughter a shorter barreled 280AI for a all round hunting rifle but in the current shortage of brass, dies, and factory ammo, I'm really considering just doing a 30-06 Serengeti so she never has to worry about finding ammo later.
