Stag,

You (and quite a few others) seem be more concerned about range limitations than seems to be appropriate in my opinion.

Folks are getting their hands on the Hornady 165 FTX bullets and others are getting good accuracy with the both the 150 and 165 factory deer ammo. The 165 will have a little more drop than the 150, but it seems to be a reasonable choice if you are anticipating longer shots.

Based on good reports out past 200 for these bullets, I am betting they do fine for expansion at any range where there is a good confidence in shot placement.

Wind drift is usually a bigger uncertainty than drop for most long range real world hunting applications.

Now a really good shooter (can read the wind much better than I ever will) with the right tools (range finder, electronic gadget with gun specific drop and drift info) and the right setting (plenty of time, stationary target standing broadside, wind not too strong, gusty or shifty) can use his modern technology to dial in scope adjustments to get within say 2 moa of perfect for drift and drop (this number would be smaller for a 300 Win Mag). The 2 moa value above is the only piece of the puzzle that is cartridge specific.

Now add in the other stuff. With bags and/or a bipod, this hunter with the skill of a sniper can probably hold within 1 moa even in a field setting. Given a 1 moa gun/load (and this includes uncertainty for temperature swings) his total uncertainty is around 2.5 moa using the square root sum of the squares method. This "optimum" condition would allow for ethical shooting out past 300 yards. This "optimum" condition is unlikely to come around for 99.999% percent of all 350L hunters in their entire lifetime.

Now lets swag some numbers for someone who is closer to say the top 1% of real guys that are both hunters and avid rifle shooters. He does his homework and has the tools to make good (within 3 moa) drift and drop adjustments (partially due to only going long when conditions are good). Lets say he is at 1.5 moa for hold but has a much better than average gun at 0.75 moa (again, long shots are only in optimum conditions). Using these numbers, the total SRSS uncertainty of 3.4 moa will stay in a 10" circle out to 290 yards. Using a Hornady 165 in this setting does not really sound any worse than a slightly flatter shooting Winchester 150. Both should still have adequate velocity for expansion. Both need drift and drop adjustments for good confidence at the ranges we are talking about.

If you can use any gun you want, and you expect a reasonable percentage of your potential shots to be over 200 yard, the 350L is not a good choice. You really want flatter shooting and smaller wind drift numbers. This is pretty obvious to almost anybody who knows enough about guns to consider shooting out past 200 yards in the first place.

On the other hand, the vast majority of hunters are good with a 200 yard (or less) effective range.

For the straight wall states, all of the guns with adequate terminal ballistics out past 200 yards have the same concerns for bullet drop and wind drift.

I really do not see a lot of disappointed hunters who pass up long distance shots because the feel they made a bad choice when they chose to use the 350L.
