Why Hammer Bullets Are Always Faster

Sometimes you need to replace a 5 amp (hornady) with a 30 amp (lapua). Especially if the system will stand 200 amps.

perfectly illustrated! I think you just won the internet for today

Hypothetically, in a .264" caliber rifle (you pick the cartridge) and it pushes a 140gr Match King at 2600fps with 40gr of your favorite powder. Again, hypothetically, how much faster would a 140 gr Hammer be with the same exact load in that rifle?

Would the speed come from more pressure? Less friction in the barrel due to materials and design?

It would be an interesting experiment for someone with the proper pressure testing equipment. Unfortunately, 99% of shooters don't have the equipment needed. But testing velocity is something the average shooter could and would do.

I'll go back to the peanut gallery now.

I'm walking on the wild side...

Yep the brass is the "Fuse" if you will

Not going to debate loading practices as people can do what they want. However, the brass is in no way a fuse or indication of safety. A fuse disconnects the circuit and stops anything bad from happening to the system. Brass can fail and the system fires fine. A cartridge case is merely a container. You don't need it at all technically - think muzzleloader or some cannons.

SMH, It's a metaphor To each their own but I disagree, why do you think that they put a gas escape port in the action ? Once again I want everyone to be safe so load at to your own experience level and stick to the book if that's what works for you. New technology = New practices, it's a brave new world

Even my feeble underdeveloped backwoods brain can think of a way.
And Lou will promptly discount it, but here goes.

Lou, you and I can both do this.

Let's drill a 1/8" hole through the hollow point and out the base of a 30 cal 124HH and a 125 accubond (plastic tip removed). Run a piece of 1/8 wire through, crimp the end. Leave the long end out the HP. With some scales and winch, we can easily see how much force it takes to pull each through the bbl. Sure. Not scientific, but I was taught to connect the dots in kindergarten.

Like this idea. The engineers in the group should be able to determine and compare initial engraving force, etc. as well as differences in required force throughout the projectiles transit through the barrel.

I test a lot. First thing I do is load beyond published data to find pressure and then back off. In every case, I get more speed with HH and even more with AH. Less bore friction/resistance = higher speeds with less pressure and the need to use faster burning powders.
As for match shooting them, I get amazing accuracy with them but at +/- $1 ea. it just isnt affordable. Also, the mindset is with Berger being best and most jumped on that bandwagon. Ive also had great results with hammers when hunting but do miss the Barnes where the petals stay on the bullet. The hammer petals can keep the dentist busy. JMO/E

1.00 each.... expensive?......if you're talking .22 cal I would have to agree.....but 27 cal and up...not in Canada.... you're still fortunate!!! ( I bet this doesn't make you feel any better ...does it?)

Peak load data in a book is for their chamber and brass your rifle's chamber is different so it may hit pressure before the books peak load or you maybe able to go over the book peak load in your chamber before you hit peak load.

Relying on the book as gospel is not smart.

Watching your velocity, primer cups and brass for your rifle is smart.

It's already been done on the Hammer Forum and the results were as expected

Would expect the results to mirror what is observed. I'm only 7,657 posts behind you, indicates I haven't had the time in the last few years of my career to keep up with everything on this site. Will check out the Hammer Forum. Thanks for info.

Dang. I shudda node better than think I had an original idea.

Pm me that link. I'd like to read all about the results
