8mm Rem Mag & Range Report - part two

[bullet]

Mike,
I bet those 250 gr bullets will do 7 jugs. More than enough for anything you would hunt with the Big 8.

JD338

Your on, JD says 7 jugs and I would pick the same. We will see, as soon as I get some jugs gathered up. Really looking forward to doing load work with it.

Man, all this 8mm talk gets a guy thinking! I was looking up some QL data on the 250 Woodleigh, it has an advertised BC of about .400.. Being the 8mm Rem Mag could launch that at around 2800, man, what a bullet that would be if it held up. I would love to see it in the jugs.

I hope to have a 325WSM sometime in the future. It'll be fun to work with the 8mm's. Never done anything with them..

This will be interesting, you guys just give me some time to get this done. I still have Hawk 250gr and 220gr bullets coming in about 3-4 weeks. And when they come in I will also try a box of Woodliegh Weld core. Both the Barnes and the Hawk have a better BC. Now because the Weldcore is a harder metal and harder core does not by any means suggest it will go further in the jugs and I think my test will finally bear that out. The reason is especially with the Barnes Original it has a copper that was annealed to make it soft and the lead is purer. What happens with this bullet and all so the Hawk is that the copper is so soft it flows back over itself and with the lead, many times retaining around 80% of it's weight.

Also, for any who wants to suggest as is found on the internet, especially by one person from a certain bullet company who tries to discredit Hawk bullets, buy saying the core will slip out of the jacket in the barrel is simply not true. This one person from this bullet company about every year puts up a post to keep this myth going. The US Army tested the Hawk bullet to see if this was true before making a big order that Hawk bullets by the way still fills that order every year. Also, the Hawk bullet company purposely built a special set up to take their bullets beyond all given and safe pressures for a popular caliber to try and make the supposed phenomenon happen. They took it so far and the pressures were so great that even though they were way over max for the powder charge trying to lock the jacket in the barrel, that the velocities fell way off proving that the obturation of the bullet was so great that the pause in the throat of the barrel, caused an increased in time of pause of the bullet in the initial throat area, actully holding the jacket tight in the lands and the core still did not slip out and all the bullets tested like this exited the barrel. In fact the Army nor Hawk could make it happen.

I have loaded the Hawk bullet in 30-06, 300Wby, 338Win mag, 340Wby and 358Win and never experienced this problem. Now I have witnessed the terminal results of a Hawk bullet on game, and that is impressive to say the least. You will find some pictures on line of the core out side of the jacket of a Hawk bullet and being a cup core bullet in certain media and at high velocities up close in a small calibers this is possible as with all cup core bullets, but you will not find anyone showing you a jacket stuck in a barrel and the core in the media, and I am for one not interested in their claims of this unless they give pictorial proof and eye witnesses who will under oath say they saw it happen and the pictures are true that it was a hawk bullet. Not hearsay, not someones claim but proof, you know, like the Army and Hawk bullets presented, real proof.

Can't wait to see the results of the 250's and 220 hornady jug test. That Hawk bullet looks pretty nice plus I love all the weight options that are available.

Wow, thanks bullet for the info on Hawk bullets. I've only heard of them and know no one with any first hand knowledge of their performance. After reading your post I immediately looked them up online and plan on giving them a call to order some to try later this week....Dan :grin:

Remember they are softer and obturate much quicker and you won't need as much powder as do other bullets to get to velocities or accuracy. Ask them for load help and they will give it to you and of course follow their advice. What caliber and bullet weight are we taking about? Is it your 8mm Rem mag?

 

[dchamp]

220 & 250 grs on the 8mm, I personally like the heavier bullets in 8 mag, 140 & 175grs on 7mm for 7X57 & 7stw & 250grs for the 9.3X62 & .375H&H. The ? in my mind is appropriate wall thickness ( .030 or .035 for deer, elk & pigs) to use and asking for load help is a good idea, thanks. :grin:

At the velocities I am going to push I want .35 no matter what I am hunting. These type of bullets will open up enough that the .35 jacket wall will hold up and allow penetration, but that is an opinion of mine based on past use of the bullet, of course will have a better understanding when hitting game with this bullet using my Big 8.
