7.7mm or .03-06?

which one do you perfer? i would take 7.7mm this base on perfernce or which you like best

 

Tough choice, but give me a BAR with AP 30.06, hehehe.

 

Assuming you mean 30.06, then I prefer that

 

mmm acually both rounds have similar performance

 

I'm curious are you referring to the original .30-03 round which was an improvement over the Krag, or the .30-06 round which was an improvement over the short lived 03 version.

They are different projectiles, different grain weights, and different powder types. Which do you mean? And BTW the .30 (in either designation) is closer to 7.6 mm.

Those two, the 03 and the 06 don't have all that similar a ballistic performance set.

 

Actually he is correct.The correct nomenclature for that round is : Cartridge, Caliber .30 of 1906 making the abbreviation .30-06

And to answer the question the .30-06 is the most ballistically perfect round ever produced

 

Not a expert on small arms but I will take the 30.06 over a rimmed cartridge orginally designed for black powder loads.
But my favorite remains the mauser 7.92x54.

 

I'm an -06 fan but I've read more than once that the 7x57mm is pretty much the perfect blend of bullet dia. & cartridge capacity. The SD & BC of the .284 dia. bullet is about as good anyone can ask for.

 

I was about to say it really made no difference until i read the person that commented the 7mm was original designed for black power...given only two choices the more modern 30-06 is possibly preferable especially for machine gun use. Both are really very overpowered actually, for hunting anything smaller than a buffalo. Probably almost no one firing either 7mm or 30-06, from a shoulder fired rifle using iron sights alone, has the shooting ability to take full advantage of the long-range ballistic potential of either round. Exactly why the Germans invented the "Sturmgewehr" which fired a round called 7.92 kurtz (short), since it was basically a round made from the full size cartridge case cut in half. Smaller, lighter, so the soldier could carry more ammo, pound for pound. Less recoil, so full auto was now practical in a weapon in between a submachine gun (underpowered) and full size machine gun (are you really going to arm every soldier in every squad with an mg-42 or m1919a3, no of course not.)

The Germans ended the war with 3 cartridges for their infantry, the full sized 7 mm (for the bolt action kar 98 and of course, the mg-34/42), the 7.92 kurtz forthe mp-43/44, and 9mm for pistols and subguns. Adding the extra caliber to logistics headaches was considered worth the trade-off in increased firepower - since by 1944 the Germans were in desperate straights.

Note also the US and Russia use 3 calibers: for US, the 5.56, the 7.62 for machine guns and the occasiona M-14, and 9 mm for the M9 beretta pistol. For Ivan its the 7.62x39 for the rpk and other machine guns and ak-47s, 5.45 round for the AK-74s, and the smaller pistol round (forget the caliber).

 

I believe some people are operating under a mis-conception here. While the Krag-Jorgensen rimmed round retained the black powder nomenclature, it used smokeless powder. They, the 'Krags' were chambered for the rimmed "Cartridge, Caliber 30, U.S. Army," round, also known as the .30 U.S., .30 Army, or .30 Government, and, more popularly, by its civilian name, the 30-40 Krag, but it was the first smokeless powder propelled round distributed by the US Army. It replaced the .45-70 "Trapdoor" Springfield which DID use 70 grains of black powder to propel its .45 caliber bullet.

The nomenclature was retained for the civilian market much as the shouldered case .30-30 Winchester designation-style was retained, generally to keep its ballistics "corresponding" to a known quality for civilian understanding. The .30-30 didn’t ever use black powder either, but the designation made it understandable when it went on sale in 1894.

 

Depend the bullets , the grains of this , and the charge of cordite , etc ...... And depend the gun whith shooting
