[QUOTE="THEIS, post: 1313508, member: 99239"] Good Day J, But how much of those "created" problems from exceeding SAAMI pressures is due to the "solution" created only took into account of changing a SINGLE component in the formula for the "betterment" of xyz cartridge instead of completely rewriting the formula? So instead of just changing propellants to increase MV in which in turn increases pressure; in which in turn creates "hard" bolt lift... So instead of just changing case dimensions and SIZE to get more propellant to increase MV in which in turn can create increased pressure; in which in turn creates pierced primers, etc.. WHY do we not change the entire formula by rewriting ALL the individual components of not only the ammunition but the weapon system too?? Action/Weapon system designed to operate at 250k pressure... Case designed to operate at 90-100k pressure... Projectile designed to greatly reduce friction force... Primer used that can properly ignite the powder column but not so big it weakens the case head... COMBINING all those components/thoughts would tend to solve the problem without creating additional problems, IMO!!! We in this industry always work to improve this and that but we still have the mindset that 60-65k is the GOSPEL when in comes to "standard" pressure guidelines because SAAMI "says so". YET SAAMI also says not to fire 9mm NATO ammunition in firearm chambered for 9mm parrabellum; as well as saying do not fire 5.56 NATO ammunition in firearm chambered for 223 Remington.....So if we pretty much disregard SAAMI on those, then why are we so "dedicated" to SAAMI pressure guidelines when we start improving cartridges...especially the ELR cartridges?
