SILENCER SATURDAY #199: Suppressed Subsonic .45-70 Government

Good afternoon everyone and welcome back to TFB’s Silencer Saturday brought to you by our friends at Yankee Hill Machine, manufacturers of the new YHM Phantom 22 rimfire suppressor. Last week we took you through the multi-host SilencerCo Hybrid 46M. This week we bring it back along with the Dead Air Primal to test out some suppressed subsonic .45-70 ammunition. How quiet can we get the Henry Rifles Model X? Let’s take a look.

SILENCER SATURDAY #199: Suppressed Subsonic .45-70 Government

As I mentioned last week, I ordered some subsonic .45-70 Government from Detroit Munitions with the hopes of testing out the performance of both the Dead Air Primal and the SilencerCo Hybrid 46M with the Henry Rifles Model X. I’m a sucker for heavy, slow moving lead, and this combination has had me eager to get out into the woods all week.

I also broke one of my unwritten rules – don’t stack two competing suppressor companies against each other, especially new their products. But since this is such a specific test and I won’t be drawing sweeping conclusions, I figured we could bend the guidelines a bit. Besides, as with all my reviews, I suggest using multiple sources of information before making any purchasing decisions. Let’s take a look at these rounds.

SILENCER SATURDAY #199: Suppressed Subsonic .45-70 Government
IQ Munitions .45-70 Government Magnuforce Subsonic
  • IQ Munitions
  • 550 grain
  • Hard cast long flat nose bullet with Hi-Tek Supercoat coating
  • New Starline brass
  • Overall cartridge length: 2.530″
  • Velocity in an 18.5″ rifle barrel: 1,000 feet per second
  • Rifling twist rate requirements: 1 in 20″ twist-rate barrel or faster
  • Muzzle energy: 1,230 foot pounds
  • Meets SAAMI pressure specs
  • MSRP: $49.75
  • Buy @ Detroit Munitions: $46.75

If you’ve never shot a firearm chambered in .45-70, the size of the brass and the bullet is a bit shocking. As you can see above, 550 grains moving at 1,000 feet per second results in 1,230 foot pounds of energy. Hunters with short to mid-range engagements should be able to ethically take any game animal in North America.

So, how did the Henry Model X do with suppressed subsonic .45-70? Honestly, I was surprised at how quiet these combos were. I ditched the hearing protection for these shots (I don’t condone this) and I’d equate the report to a suppressed.45 ACP pistol. In a hunting situation, I could see some shooters leaving their plugs at home.

As for the head-to-head showdown, my subjective conclusion is that the Primal is quieter than the Hybrid 46M when shooting subsonic .45-70. The difference is small, probably the minimum three decibels that the human ear can actually detect, but it’s there. As a reminder, these two silencers are built to suppress dozens of calibers and hosts. Your specific needs may be just as unique as .45-70 subsonics, or it might be completely different. And I’m just a moron with an opinion.

    Based on external dimensions the primal seems to have the larger volume. I know there's more to it than that but if the difference is that close...
