Re: A-max's for hunting?

Someone mentioned the tough shoulder shield of Boar pigs. Well, as a hog guide and also as a ballistics researcher, I try to keep abreast of this stuff. To be humane, I cut out the shield of a neck shot boar, exactly 1" thick- all cartillage. I put the shield against a dead goat of all things. I went back 50 yards and shot it with the 162 grain Amax at 3275fps. It went through the shield and into the goat but turned to dust, much like a .224" Vmax at close range. Wounding through the goats lungs was reasonable. The test proved that the Amax could pass through the shield with the potential to create a wide wound. Nevertheless, I just wasn't happy about the total disintegration of the projectile into dust- literally powder, rather than larger fragments. Not happy enough to take the test further onto a live, mature boar.

To this end, I have refrained from using the Amax as an "all around" bullet for pigs from the 7RM and RUM. In the 7RM, I really like the performance of the Amax out past 300 yards but its just not the same as a more versatile bullet that works equally as well (penetration) in close. Its OK for sows or young boar pigs, just not my idea of a suitable choice for mature boars. I get to see a lot of boars run off when hit with unsuitable loads so I am kind of overly careful about suitable loads for these guys.

I would rather use the heavier 180 grain VLD in the 7mm as an allrounder for shooting at both point blank ranges out to 700 yards or more. Its either this or if I am using a lighter bullet, then it needs to be controlled expanding. I liked the post that mentioned loading a .300 with either the 150 grain Interbond or a heavy soft bullet as an alternative. When I hear a post like that, I know that the poster has shot a lot of animals- kind of what it takes to form that kind of experience based opinion.

I have the video footage of the rather weird shield test somewhere in this laptop, not that it achieves much. It was just a preliminary test that I wanted to perform rather than shoot and wound a large boar with the Amax at close range.

Someone also mentioned the .30 cal being more flexible due to heavier Amax offerings- its a valid and highly relevent point. The .300's loaded with heavy yet frangible bullets have great potential to produce "all around" performance, more so as we expect rifles to perform at both point blank ranges out to and beyond 1200 yards.

Re: A-max's for hunting?

So should I stick with the Berger 180 I've been trying to make shoot in my rifle? It sounds like it maybe the best all around bullet available for long distance shooting. I could do the 2 bullet thing but I would rather stick with one if possible.

Re: A-max's for hunting?

Yes, by all means, stick with the 180VLD if it shoots well for you. It does ofcourse have its limitations with regards to game body weights but for the most common species of game, is a good allrounder.

If you want a stouter bullet for that will shoot to a similar POI, the 175gr SMK is an option. Both (VLD/SMK) shoot the same out to 400 yards or so but you will of course, have to double check that both do indeed shoot to the same POI from your barrel. The SMK is kind of better suited to tough boars however, I haven't bothered to dual load. If I was to pick a bullet ideal for tough boar (exit wound/ free bleeding) in the sevens, it would be something like the Accubond or Partition but in doing so, I would lose my LR performance so as compromises go, the VLD is perfect.

A muzzle brake, a heavy barrel or supressor has the ability to dampen harmonic vibration to the point that you can shoot two loads of differing weights/styles/velocities to the same POI or same verticle line- ie 180VLD 3" high at 100/ 160AB, 2" high at 100. Vibration dampening is one way to get around the variations encountered with dual loading. Something to keep in mind if you feel that you would like the option of dual loading.

Nate..I agree with your assessment. I have made the statement in the past that there are long range bullets and there are hunting bullets, but here are no long range hunting bullets! There are some target bullets that work for given conditions and distances and that is why we use them. This is exactly why I make my own bullets for long range hunting.....Rich
