I saw this Video and had to post it because of the amount of miss information in the video.
There are many reasons to improve a cartridge. The main disadvantage is that most of the time you will be required to reload.
The advantages are many, and worth the effort in many peoples mind. You can Improve a cartridge for many reason, An Increase or decrease the powder capacity, lengthening or shortening the case to better fit the action,
improve the efficiency of the powder consumption, (less powder to get the same pressures), Better case life because of less case stretching, Less bolt face thrust, Less case length growth requiring neck trimming and thinning, And so On.
The original reason to create an improved cartridge was to make better use of the existing powders of the day. This has been almost eliminated with the wide variety of available powders, but does not eliminate the reason for Improving a cartridge.
In the video He talks about the case stretch upon firing the improved cartridge. This does not happen If the improvement is done correctly (Like Ackley recommended with .004 thousandths case compression) If done correctly, case stretch is all but eliminated and If loaded correctly, trimming is almost non existent for the life of the case. also the advantage of a properly chambered improved cartridge is the fact that factory ammo can be fired in the improved chamber with exceptional accuracy. (Many times factory ammo will shoot better in an improved chamber that the factory chamber because it is held stationary during firing and has no head space
that would allow the cartridge to first move forward at the firing pin strike, and then being thrust back against the bolt face increasing the bolt thrust and case stretch.
Good information is great, bad information is harmful and can be dangerous. The information I have provided is not my opinion, It is known facts with proven results. If some don't agree that Is their choice, there is a lot of science and trial and error in Improving a cartridge and if the person improving a cartridge doesn't understand the cause and effects of making changes to a cartridge design, he should stick to the factory cartridges even if he reloads to avoid self inflicted problems.
Sorry about the rant most of the time I like his Videos, but he obviously doesn't understand the proper way to improved A cartridge and the benefits so I will leave it at that.
