We know that. The discussion had drifted to the supposed rechambered 94 Winchester. The 1895 and the Savage 99 with its rotary magazine were well suited to spire point and round nose bullets. Some Remington pump action rifles with tublar magazines have spiral ferrules that guide the cartridges so the bullet tip can't touch the primer, these were suited to spire point bullets as well. Some European bolt action tube feed rifles used ammo with a deep annular groove in the casehead to hold the tip of a bullet away from the primer. The taper of the case helps keep the bullet tip tilted away from the primer. This sort of safety factor is not fool proof because under heavy recoil or shock of being dropped cartridges don't always stay in the orientation they should be, and a weak spring can let the case shift position and bullet nose jump out of the groove. If a Winchester 1894 is rechambered to .303 Savage one might never run across a factory load that had a bullet entirely unsuited to use in a tube magazine, then again since the cartridge was not designed with a tube magazine in mind some manufacturers may well have used bullets entirely unsuited for that purpose. German commercial ammo with the wire insert is an example. The wire insert was used by some U S manufacturers as well. It was intended to allow an extremely soft exposed lead nose that would not be easily deformed by hard contact with a feed ramp, and give good initial penetration on thick skinned game before rapid expansion on further penetration. A wire point round or blunt nose would be very dangerous in a tube magazine even with light recoil. With the ridiculously high number of ammunition manufacturers recalls in recent decades I no longer automatically trust them to use due caution in chosing components. I've had Winchester factory loaded .303 cases split lengthwise on first firing in several Enfields that have tight chambers and headspace within SAAMI limitations. Those cartridges were fresh and straight from the factory in the mid 90's. Years later I compared some of those cases to mid 80's HXP milspec .303 and found that from boxes of each several cases had the exact same overly wide relief groove just above the rim. To the eye these cases almost certainly came from the same source, and the case drawing equipment was begining to get long in the tooth. I found that The U S had supplied Greece with ammunition manufacturing machinery after Britain cut off all post war aid in 1948, so its likely the equipment was WW2 surplus Winchester/Olin machinery. Anyway, I don't trust recently manufactured factory ammo, so any recommendation I make will be tainted by that distrust. With a flat point chain fire is almost impossible, with a roundnose chainfire may be unlikely, or even highly unlikely, but I'll stick with the reasoning of those who originally designed the Winchesters and use flat point bullets only when the cartridge is a centerfire. I can't see that there would be any real advantage in a round nose over a flat point in cartridges of this class, and flat points are considered to increase knock down power and bone breaking ability. Some like to use spire point bullets with one round in the chamber and one round in the magazine, which sounds safe enough. Like i said I may be in error, but if so I would prefer to err on the side of caution. I don't trust the quality control or decisions on components, often from subcontractors, of modern factory ammo, so those who have more faith in the manufacturers than I do can give their own recommendations based on that faith. Marlin has issued similar warnings on availability of unsuitable bullets, both pointed and round nosed, for their pistol caliber leveractions, which can be expected to have much less recoil than a .30-30.
They wouldn't be making factory ammo with a round nose bullet for the 30-30 if it was an issue. |
At It's most basic it has been and remains an issue to be taken into consideration, those manufacturers you mention may have complete faith in the measures they have taken to eliminate the risk, but if there was never any risk they would not have taken measures to reduce that risk. Since I have no reason to have faith in the manufacturers I can not recommend any round nose bullet based on their faith in their product. A primer normally must be deeply indented by a firing pin to ignite, but a loose fitting primer need only be pushed deeper into the primer pocket for the anvil to compress the priming compound and detonate. Even a soft exposed lead round nose can exert that amount of compression, it need not be a hard pointed bullet.
