Speer .458 350 Gr. Mag-Tip in Marlin 1895

Robert MermelsteinNathan wrote the following: "The Mag-Tip’s flat nose profile enables it to be used in tube magazine rifles."Some years ago I asked a Speer technician if that bullet was safe in a tubular magazine fed rifle, and he emphatically replied 'No'. Has the meplat of the bullet changed since many years ago, or was the technician parroting a lawyer-approved talking point? |

Nathan FosterRe: Speer .458 350 Gr. Mag-Tip in Marlin 1895Hi Robert, as I wrote in the knowledge base, this bullet was designed as a light weight projectile for the .458 Win Mag. The light weight (high velocity), low SD and flat tip help the bullet to dump energy while the low level bonding helps it break down slowly so that it can produce adequate penetration.The Mag Tip was not designed for the .45/70 or tube magazines. The ogive is narrow compared to other lever flat points. I should not really have said that it can be used in this manner. You will note that I said the same about the Hornady 350 grain Round nose ()also designed for .458 Win) and went so far as to take a hammer, projectile and primed case, giving the primer several hard strikes to try and set off a primer. Nothing. Still, I should not disregard the manufacturers warnings. Note also that the 350 grain Speer produces a fairly long OAL. This length works out OK in the Marlin but is too long for some lever actions. If you want to, you could try applying a small but shallow hollow point. This would remove the contact point at the anvil of the primer, weaken the lead (even though contact area is decreased) and enhance terminal performance at low impact velocities. |

Scott StruifRe: Speer .458 350 Gr. Mag-Tip in Marlin 1895Is there any evidence, even anecdotal, of cartridges in a tubular magazine going off? |

Nathan FosterRe: Speer .458 350 Gr. Mag-Tip in Marlin 1895Hi Scott, I have not come across any evidence of round nosed or narrower flat points detonating. Note the narrow form of the .30-30 Remington Corelokt soft nose ammo. This ammo produces lower recoil inertia than warm .45/70 loads but the fact remains, the projectiles are shaped to quite a point. Along with these, Remington produce a round nose jacketed hollow point, reminiscent of the earliest .30-30 designs. Speer bullets designed for tube load mags are flat tipped, but not always wide, so much so that they can be quite useful as bolt action rifle loads for use out to moderate ranges.Still, I wouldn't want to push this point too far. |

Scott StruifRe: Speer .458 350 Gr. Mag-Tip in Marlin 1895If you’re lucky enough to own a lever gun that shoots MOA or better, and nostalgia compels you to hunt with it where shots of 200 yards or more are likely, modifying the meplat of a lead tipped spire point with a DIY hollow point is a great idea. You could easily test whether they’re safe in a tubular magazine by loading some rounds with no propellant. The primer will create enough pressure to drive the bullet out of the case, assuming the magazine spring gives enough for the bullet to leave the case. We know that because it’s why cases have to be loaded with minimum powder to ensure detonation. Otherwise the primer can cause the bullet to lodge in the bore - an extremely unsafe condition. |
