[QUOTE="J E Custom, post: 205128, member: 2736"] J300 I wouldnt be two hard on your smith because he probably thought he was helping you out.(Not defending him )but he should have explained how much bang you were getting for your buck. You did'nt hurt your self and second thoughts are your worst enemy when building a custom rifle. Most all smiths have an opinion as to what is best for its intended use and I am no different "BUT" I do tell the client the advantages and disadvantages of each choice and then let him/her make the decision. As to the term "IMPROVED" I have owned several P O Ackleys that were built by himself and they were originally based on cases with fast tapered bodies and 25 to 35o sholders. These rounds were truly Improved by blowing the body out to a minium taper that minimizes bolt load and improves brass life. Also by changing the sholder taper to 40o or more it added volume but most important was that it improves/changes the burn rate and pressure wave inside the case making it more accurate most of the time. On the more modern case designs they are now doing this for the same reason. Efficiency, capacity,bolt loadwith higher pressures, and accuracy. So as some of the others have said you may not gain much velocity but it should be better if only by a small margin. So the term Improved should in some cases be called Inlarged,Changed, Wildcat'ed, Modified But not "Improved". So my recommendation is to shoot and enjoy your new toy and I can tell you that you will be empressed if the smith did his part. J E CUSTOM [/QUOTE]
