Why are so many threads turning into pi$$ing matches tonight? I am going back to finish organizing my hunting cabinets. At least the the only arguing there is with myself about where to put what.

So Wal-Mart is the deciding factor in what is a " factory gun/caliber" and what is' nt? Danny if thats the measure then you must exclude most WSM and WSSM, Rem Ultra and Short ultras, most any Weatherby mag and rounds like the STW as Wal-Mart typically has a poor or non-existent selection of such calibers and ammo.

So what is the flatest " Johnny Wal-Mart hunter" caliber? Well since the flatest thing they typically carry ammo for is the 7mag and 300Win Mag then those MUST be the fastest and baddest on the market... yeah thats it! Gosh I' m ditchin my Warbird and forgettin the plans for a 50. I think I' m gonna get a 30 Carbine.

Nevermind, Corvettes are the fastest cars on the roads because thats the fastest thing the Chevy dealers carry (those Ferrari and Lamborghini dealerships are simply figments of our imaginations )!!!

I can see how the Lazyroni cartridges get their speed........load em with specially lubed bullets ie. nP3 from robar and run them at extreme pressures. I looked at the warbird reloading data and the loads run from 66,000 t0 67,000+ psi at a mild 70 degrees.......[]wonder what the pressures would be at 100 degrees?[]. Are these cartridges listed with SAAMI and have their approval?

What about the .220 Swift? We are talking about going to Wal-mart and finding shells for it right?

The flattest trajectory was a simple question that turned into an arguement between people which neither one asked the question. Chevy, Farrari, warbirds, or Remington ADL' s chambered in a .270...Who cares. Just a simple question.

Hard to beat the 7mm' s due to their high Ballistic Coefficientcy. The 175g Partition has a BC of .519! I didn' t see any in my Nosler reloading manual that has a higher BC and, pushing at a very high velocity, will ensure a very flat shooting round. For a factory offering the 7mm Ultra Mag would be hard to beat unless you added in the Lazzeroni 7' s;

They have a 120g Warbird that is going almost 4000 fps and, with a 300yd zero, only drops 14" at 500 yards. Of course, as was mentioned, they use a lubed bullet to keep the pressures from maxing out and are very expensive (~$100/box).

Geeze, I wasn' t trying to start a pissing match. And if you' re going to quote someone, look at the entire quote. I said, Wal-Mart, or some place like it. Where can you go to get Lazzeroni ammo? You certainly can' t go to just any sporting goods outlets, or even very many gun shops and pick up their ammo. Does Winchester make their ammo? How about Remington, or Federal, or even Hornady?

And as far as your comparison on cars, you' re a goober. We all know the fastest " domestic car" is the Dodge Viper. And there' s alot more places to buy Lamborghinis and Ferraris than there are Lazzeronis.

Atually the fastest " domestic" car would be the Saleen S7.
0 to 60 in 3.5 seconds and a top speed over 200 mph.

Sorry I couldn' t resist.

As far as the flattest shooting cartridge, loaded by one of the major manufacturers, would probably be the 30-378 Wea. mag. Of course these cost just as much as Lazzeronis' cartridges do.

UUUM...The Grand National GNX had the same 0-60 so you can' t forget it too....JDinAB

my votes for the 7mm.

Which 7mm?7mm refers to the bore but does not describe a cartridge.As for the gnx the 0 to 60 time is listed at 5.5seconds for a stock vehicle.
