I have quite a collection of Handi Rifles. I recently bought a hand gun chambered in 444 Marlin. Should I buy another Handi Rifle in that caliber? Does any one have that barrel? Can I just but that barrell and put it on one of mine?
I guess I am getting to the point I figure I may have a few too many of these Thoughts??? Hank |

Is it really that simple? AH HA! Another meaningless and statistically insignificant test in the making! Let's see... I can load three batches of ammo, all the same except for ... Nevermind, I agree with Bill... ![]() |

Boy this is a loaded question. A just war should be determined by the reasons it is fought. Vietnam, and Iraq were fought because the United States Government took it upon itself to judge the governments IN OTHER COUNTRIES, when it's really none of our business. It is now obvious to any paying attention, that it took someone like Hussain to keep the numerous factions from wiping each other completely out.
Afghanistan I have mixed feelings on. I think after 911 we should have unleashed out Air Force on the known terrorist camps, and bombed them into powder. This would be far more economically effective, and there would be no need to occupy or rebuild that 15th century country, whom has not the slightest interest in democracy. |

All wars are just wars depending on who you ask. The thing you should always bear in mind is that the history books are always written by the winners.

You can use the existing rail system and add a 3rd rail for wider trains, like a Lionel toy train. The wider trains can go faster and take the turns because of the lower center of gravity and wider foot print. Basically you double the width, you can carry cargo in containers side by side and double stacked. Wider passenger cars can carry more passengers and maybe even their personal cars in car carriers with the passenger trains. When they get where they are going, they get their cars off the train and use them at their local destination. Existing trains can travel about 180 miles and hour with no modifications. That is fast enough with existing technology, wider tracks and wider cars. Existing trains can use these same tracks but only two rails, the middle and one side. No new property to buy. If you go monorail, you could make it for passenger use only with aluminum trains so the monorail system wouldn't have to be so heavily made to support it. It could be done over a 20-50 year period, just like the interstate highway system which took about 20 years or longer to complete.

The 460S&W has the same size case head as the 45 Colt and 454 Casull at approx .478-.480" depending on who's diagram you use, SAAMI MAP for both the 460 and 454 is 65kpsi, the 460S&W works fine on a modern SB2 frame, I get nearly 2900fps with the 200gr Hornady factory load in my 20" H&R, accuracy is 2½-3" at 100yds. The rim size of .512" has nothing to do with case head thrust(bolt thrust), it's calculated using the internal case head surface area and the pressure.
Tim http://stevespages.com/page8d.htm http://www.lasc.us/SAAMIMaxPressure.htm http://www.riflebarrels.com/articles/custom_actions/bolt_lug_strength.htm Bolt Thrust Bolt thrust is easy to calculate. Only two inputs are required. They are peak chamber pressure in PSI and as mentioned, the inside area of the case head that the gas pressure can work on. The formula then is: THRUST=AREA*CPSI Where: AREA=3.1416*(HS/2)^2 |
