270 chamber pressure

For exam-ple, at a common sterilization temperature, 270 degrees C, the pressure shown on the steam table is 41.85 psi absolute. handloads averaged nearly 69,000 psi, well over its SAAMI MAP of 65,000 psi. Likewise, the .270 WSM kicks a little less than the 7mm WSM, … I have also had 270/308 Norma and 270/300 Win. When the same amount of pressure is exerted against 150-grain bullets in the .30-06 and .270 Win., velocity will be a bit higher for the .30-06 for two reasons. chamber pressure has been well established by experimental means. Under these conditions, your lungs can gather much more oxygen than would be possible breathing pure oxygen at normal air pressure. The 1908 DWM seems OK with high pressure loadings with standard cartridges (270 Winchester). The .270 is a high-pressure round, higher by a considerable margin … The 270 Wby will see 3250 and 3450. So if the highest rated pressure for a cartridge is 65,000 psi, most manufactures will design to 130,000 minimum but I don,t advise that you exceed the design pressure because you will be cutting into the safety margin. I think one could use loads at 270 saami pressures with no issues. The .270 Winchester is a rifle cartridge developed by Winchester Repeating Arms Company in 1923 and unveiled in 1925 as a chambering for their bolt-action Model 54. The Pressure value used for each caliber happens to be the maximum SAAMI safe chamber pressure. In 26" barrels the 270 will see up to about 2950 with 150 grainers and 3150 with 130 grainers. For instance, in rifles of the same weight and shooting bullets of the similar sectional density loaded to the same pressure, the .270 Winchester kicks less than the .280 Remington or .30-06 Springfield. In a hyperbaric oxygen therapy chamber, the air pressure is increased two to three times higher than normal air pressure. As you can see, the calculated results are pretty accurate and closely reflect values you would expect. .270 Winchester . When steam tables are used, a common mistake is to obtain a Steam tables always list absolute pressure, not gauge pressure. 60,000 .35 Whelan: 52,000 cup ... SAAMI Pistol Pressure Specifications (Maximum Average pressure) All Piezo measurements unless specified) ... Chamber & Cartridge Dimensions. 65,000 .351 Win SL: 45,000 cup.280 Remington . If you are happy with max 270 Win ballistics any of the 270 mags will give those with reduced loads and no pressure and case life just this side of forever. Its larger base diameter gives propellant gas a larger surface area to push against and a shorter bearing surface makes it a bit less resistant to being pushed down the bore of a barrel. The .270 Win. The rifle manufactures design there actions around this pressure and add a safety factor of 100%. However, if you are one who likes to push things a little, there is a real good chance of setting the lugs back in the receiver. The .270 may be a good all-around North American chambering in the minds of some, but to me it fell short because of the limited bullet weights available (now that has been corrected). Interestingly, not long afterward, Western also pressure-tested a bunch of handloaded ammo, put together by a major bullet company using a popular computer program for predicting hand-load pressures and velocities. The locking lug seats are a little on the soft side. About Leverguns. Current Levergun Makers. Psi absolute the soft side much more oxygen than would be possible breathing pure oxygen normal!
