the lvl 58 mk10 14"s have a much spread than the lvl 68 Mk7 14"s

if you are having trouble with the spread on the nevada/tenny41, you should take advantage of this current event and add boost/vets/experts to your gunners. 

The spread of each gun set (lvl58 14"s, lvl68 14"s, lvl 70 16"s) is different, even with high level gunners.  

lvl58 mk10 14"s have better spread than the 16"s, which have better spread than the second set of 14"s

Within each set of guns, you'll get the L, D, and the "regular" version, N, options.  L guns have the most range, D guns have the least range, and the N guns are in the middle.  (The reload time is also longest for Ls, shortest for Ds.)

That being said, the D guns will natually have better spread simply because the shells do not travel as far (think about a shotgun spread).  But in BB play, range is so critical that you almost always should use the L guns (with Light shells). 

Again, if you are having trouble with the first set of 14"s, do some AA in games to increase the experts on your sailors, and use vet conversion events in the future to increase your vets.  You may be able to get boost/vet/expert items from this current event too. 

On a side note, if you plan on going far with your BB crew, don't over-vet your gunners. 

I`m just going to clarify the general terminology for you so we don`t get confused.

Boost = premium sailor.  It`s available from events if you are lucky or by purchase with $$.  It increases the ability of your sailor by 20%. It can be applied at any level - the result will be the same.  It stays with the sailor forever.

Elite sailors can once again be won in events, or purchased with $$ or from other players who have them.  Those sailors (elite engine/fighter/repair) come with a +13 stat.  This is not like the boost, it is an actual sailor so you will have to level it from scratch.  A boost can be applied to this sailor to further increase its abilities.

Experts->vets.  Yes if the conversion fails, you lose the experts and have to go back to recruits.  But consider that if you are able to convert 10experts(skilled)-> 10 veterans(officers), the performance increase from just 10 vets is equivalent to that of 40 experts.

If you are going to try to convert, at least purchase a premium account.  Also wait for a "conversion event" where the rate of success is increased.  Combining a premium account with a conversion event is the best time.  Also it's great if you can have extra expert packs(available from events or by $$) to refill any conversion failures so you don't have a huge drop off in performance.  Generally if you have premium account + event, you should be able to convert 100 experts into 50-70 veterans(**when that sailors has zero veterans to start).  Even if you can't refill the experts, you performance will be better.  Think of it this way - If you get 3 conversions out of 10 tries, you are already better off than before.  Please note that once you get close to or over 100 veterans, it becomes more and more difficult to convert to vets and at that point you must have a premium account + event to have any success.

boosting means using the Premium Sailor item, which increases sailor ability by 20%.  You would have to get this thru events or buy it from the store.

as for expert to veteran conversion, the lower number of veteran you have, the easier it is to convert.  ie.  the chance of a successful conversion from 10 to 20 vets is a lot higher than 90 to 100.   To have a 100% conversion rate, you will need to use the Veteran Items

It is actually a good idea to NOT get a new ship the instant your BO can use it. It might take a few levels, but wait until your gunners have the level for the ship's intended guns (their L version which even comes 2 levels later).

You could do this more easily levelling up two BOs (from the same nation), on different BB lines. Always take the gunners with you when you switch between the lines - that ensures that they will be ahead of the BOs.

Dual 16" have better spread, range and maximum damage. They fire 1 shot less per turret though.

...And I'd recommend it over the BB2 Trip 14" any time.

Haha ok thnx guys on explaining me some things...anyeay i used my ace fighter(just one) with P-55 ascenders on Enterprise and damn it was funny....and i didnt know that no metter how  play those cv's are giving so much xp and credits i made loads of credits and xp to get to remod of tenny in no time.....although i dont have anymore scout pilot that i had(now he is that ace boosted) but was worth it...since those planes that i use(P-55 short ranged but verry fast and offensive)i sail close to the BB and scaning the area waiting for the bombers as soonest i see them i unleash hell...usually non of them gets to the bb or if it menages to get they dont return home:))...now lets talk about that tenny....god one bb with verry good spread at the beginig...i had oportunity to test that on some bb3....he got lmoust killed by in the first hit took him out more than 60% offf his HP (was kinda small bb)....but some other BB that was closer than me finished him off while i was reloading..and that was at max angle....but if ever got borred off it and i want to advance more quicklly i just take out my CV :)
