Hi Guys,
I landed a 110 LA for very cheap, and and am researching an elk round. I found 180 .277 bullets for my old 270 Win, so I am not interested in a .284. I want a .308 or a .338, with relative ease of brass/ammo availability, and something reasonable (no ultras, etc.). So this leads me to the old belted magnum cases, the 300 and 338 Win's. I am aware of their disadvantages, but they will suit my purpose just fine.
So here's the data I'm using to compare:
200 gr, .308 accubond at 2970fps
225 gr, .338 a.b. at 2880fps.
This comes from the Nosler manual, and both are quoted with 24" barrels. I use 40 degrees, 8500' elevation, and a 200 yard zero. With that, I find the 300 and 338 right on par energy-wise to 700 yards (the point where energy levels drop below 2000ft/lbs, the number I use to establish max elk range), with the 300 shooting about 15" higher.
Now, I know there is more to the comparison than just energy and trajectory, and that's what I want to hear.
Is a 200 grn in a 300 getting close to maxing out the mag box?
How would these cartridges act in terms of efficiency in a shorter (20-23") barrel?
What about shooting a 250 gr accubond from the 338?
Any other thoughts on these 2 rounds?
Thanks guys,
Adam
