[QUOTE="Fiftydriver, post: 60986, member: 10"] A 25-06 getting 3650 fps with a 100 gr pill in a 26" barrel. I think that says it all. No offense my friend but I still believe you are far past any safe working pressures if you are getting these velocities. The throat design you use is no different then any other top end custom rifle builder in the country including my self. I do agree that building the reamer for a specific brand of case will limit expansion to some degree but I will also say you are still dramatically over the 65,000 psi limit weither your seeing the signs in the case or not, the rifle is still having to endure probably +70,000 psi pressure as well as your throat and bore. But to each his own again, if it works for you thats great but I certainly would not recommend to others that the 257 Wby is a +3800 fps round with a 100 gr bullet or a +3600 fps round with a 115 gr pill. Likewise, pushing the 7mm STW to 3900 fps in a 27" barrel is flat insane at best even with a 120 gr bullet this is an extremely high pressure load. If your rifles are properly built, you will not feel any increase in bolt life until well past 70,000 psi, non of mine do and many of my customers used to factory rifle will blow primer pockets totally out of their cases because they think judging bolt lift is an accurate way to read pressure, it just is not in a rifle that has beed trued up correctly. Only thing you are doing is removing an early warning system that is built into the rifles. That is dangerous stuff my friend. Have you even heard of a little thing called "powder detonation." If you knew about this you would not be doing what you are. Again to each his own but I think your running the ragged edge and asking for a liability problem if you keep pushing these velocities to others. Just my opinion, Kirby Allen(50) [/QUOTE]
