Speedy hammers

[nealm66]

To rosebuds question though, I would have to think it's a combination of powder burn rate, less bearing surface, rifling and chamber. Maybe a deeper grooved rifling would be slower? I have noticed that all my vanguard rifles will run almost 100fps faster than same caliber in some other brands. I've also noticed they have sloppy headspace. Definitely hammer bullets are changing the game and probably hard to swallow for some. It would be nice to know the reason behind rosebuds question.

Ok I have to throw something out there after skimming through this. I had a similar experience with the SAME rifle, loads etc. Was using my chrony at the range, packed it up and went somewhere else, and set it all back up and all of a sudden was getting faster readings. I knew something was wrong, power cycled the chrony, made sure the plastic strips were straight etc, same issue. I went back out to adjust to make sure I wasnt off axis and when I touched the front of the Chrony I felt it fall and hit the metal hinge stop. It appeared that I had not fully opened the Chrony so the little optical sensors were angled in toward each other. The error couldnt have been more than a fraction of a degree, but when you are trying to measure a 3000fps projectile in a distance of about 10 inches, I guess it doesnt take much. Not sure if your chronograph is a folding style, but if it is, it is worth looking at. I moved to Magnetospeed for this reason.

Magnetospeed is all I use. Set up is easy and I don't get ghosts off the guy's shots next to me at the range.

I checked everything, even went in the House and pulled another rifle out of the safe I knew the speed of and had a turret made for. And shot it. It was on the money. The chronograph was good. I had trouble believing it also. But the little kimber was shooting25-06 speed. combo of new and better bullets , and new and better powder.

thanks guys for the info I looked at them a couple times but it didn't look like the bc was real good, but 200 fps extra would make up for that. I might turn that new 270 in to a western yet. Do they make a mess when they hit the target meat loss.

You'll never wanna shoot anything else,

No. Bang. Flop. DRT. Clean wound channel and little blood damage. I shot a cow elk and a decent muley buck last November with my 300 WM and my 280AI, respectively, with those exact results.

Surprisingly very little meat loss. They engineered em for meat hunters. They shock, pentrate, and don't bloodshot like a cup n core. I had a complete pass through on a 300 lb boar through both shoulders. Took him off his feet and both front quarters were still edible.....with a 98 gr bullet.

 

[dogz]

Yeah, explain how I touched 3400 FPS in a .300 WM with a 196 grain bullet.!!

easy peasy..........pressure equals speed and speed equals pressure no free lunches buddy boy

I had issues about two weeks ago with Barnes 120 TTTX , and talked the owner of the rifle into buying hammer bullets. He called the makers and purchased two boxes of 124 Hammer Hunter, s and two of 110s. In .264 for a Creedmoor. Worked up a load without to much fuss with the 124s . rifle is a kimber 84M 16 inch barrel with a break. The 124s shot 2725 into a very nice group. I had been playing with the 110s in my Christensen Mesa . I was using46.1 of STaBall 50 thousands off the lands. Shot pretty good at 3048 FPS. Thought I could get more but put it aside to work on the kimber and the 110s. Found the lands and set it 50 thousands off, good but not great. Went 60 thousands , bingo. Right at half inch with a twitchy little gun. Brought it home and fired it over the chronograph, I turned it off then back on. Same thing 3248 FPS, out of a 16 inch barrel. Shot4 more times to confirm. ES was 16 FPS. I was gobsmacked. No pressure signs, easy bolt lift. Any answers? Oh, same load as the mesa. 46.1 STaBall

I am finally loading my .30 cal 124s in a new Sauer 101 I got for half price and couldn't walk away from, even after selling my other magnums due to neck and shoulder injury/surgery. So I'm loading it down to .308 stature. I thought the 124 Hammer Hunters would be plenty for our generally smallish Southern deer. I'm only charging in the lower - mid 60s with things like IMR4166, H4895, and Varget. With a 24" barrel and Rem 9 1/2M primers, I was figuring only around 3200 ft/s, but I may be surprised. I hope to try them out this weekend, so if they are off the charts, I'll try to report back to this thread.

Hell I've got premium bullets I'm saving just to fireform brass. I'm loading everything I own with Hammers.

Hotty toddy, gosh a-mighty, bim bam, the deer is down - Rammer jammer with a copper Hammer!

ok im sold gonna get some

They were showing up 2 days after an order was placed... no "out of stock, overdue". My second batch took a couple weeks, but they notified everyone they were out for a few days. Generally, they ship same day or next day if it's late.
