I have loaded both the 140 SBDII's and the 170 EOLs in the same .270 Sherman, so I have a good comparison of the two. Here is what you end up with -
100 yd zero
6600 ft elevation
10 mph wind drift
140 SBDII @ 3300
170 EOL @ 2950
400 yds
Velocity - EOL - 2535 // SBDII - 2837
Energy - EOL - 2404 // SBDII - 2502
Drop MOA - EOL - 4.75 // SBDII - 3.5
Drift MOA - EOL - 1.0 // SBDII - 1.0
600 yds
Velocity - EOL - 2324 // SBDII - 2618
Energy - EOL - 2039 // SBDII - 2130
Drop MOA - EOL - 9.75 // SBDII - 7.5
Drift MOA - EOL - 1.75 // SBDII - 1.5
800 yds
Velocity - EOL - 2134 // SBDII - 2408
Energy - EOL - 1719 // SBDII - 1803
Drop MOA - EOL - 15.25 // SBDII - 11.75
Drift MOA - EOL - 2.5 // SBDII - 2.25
1000 yds
Velocity - EOL - 1953 // SBDII - 2208
Energy - EOL - 1440 // SBDII - 1516
Drop MOA - EOL - 21.5 // SBDII - 16.5
Drift MOA - EOL - 3.25 // SBDII - 3.0
Plus on game we have seen better penetration with the 140 SBDII, and have used both the 170 and the 140 on elk. The 170 did not exit a large cow with a broadside double lung @ 910 yards, the 140 entered front shoulder end exited mid neck on a large cow at 400. Also have used both on quite a few deer and pronghorn. Both work well, though I feel more comfortable on elk with the 140's so far. Add in the significant jump on ballistic performance, and they are hard to deny. Plus, they are available. The only downside I have yet to find, is that they are expensive compared to Bergers.
If my hunting was going to stay under 500-600ish yards, I would also give the Hammers a hard look.
