Given that the 3033 is one of my favorite bullets for the .308 Winchester, I had to try it. It is close, but the taper starts just a hair to quickly.

getting a little nervous about ammo. i still have a few rounds left, but i'm not going to be laying down a blanket of fire at the 300 yard runners anymore

judd, i like the sound of the thuds too, but the screams give me mightmares

[censored] send it DJ. Nice work You got away from shooting dirt clods Is see?

Bill, I have a question about brass life, I've been reloading for my 300 Hamr for over a year now. I've found that with as little as 3 firings I'm getting almost 25% of my cases sticking in my decapping die. These are WC Hamr cases and I'm loading straight off of your web site data. I started with the Lee dies and thought maybe there.was a problem. so I just ordered RCBS dies last week and things didn't change. I then annealed my cases, something I don't usually do until around 5 firings, and that was no solution. Is there something wrong or does the 300 Hamr have an .usually short case life? I've been reloading for 40 years with several different calibers and have never seen anything like this.

pic for attn...

bill,
i thought i was bumping the thread so this guy's post wud b seen when i posted the pic, but i think i stepped on it instead. here it is again. i'm kinda innersted in it myself. i've stuck a few cases because i stretched the web with hot loads. but the worst part is when they jam in a hog fight. arrrggghhhhh

so, gsi.. are you decapping separate from sizing? if so, that's really odd to stick cases with a decapping die

First, what do you mean by "sticking in my decapping die"? Are you pulling the rims off the case during sizing, or are they just harder to pull out? How are you lubing the cases during the sizing process?

For what it is worth, I've never run across a problem while reloading or firing the HAM'R.
Early on, I ran a small batch of Starline cases, along with some cases formed with Lake City surplus brass, through the reloading cycle over and over just to see how long they would hold up. This test was before SIG was producing any HAM'R cases and they were not in my test. My process was simple, I would fire a round and then resize using RCBS Case Lube-2 applied with my fingers. Then I would just wipe the lube off with a clean cloth and reload. I could then step outside and re-fire the round again to repeat the process. After the 9th reloading I had a case neck starting to split on one Starline case. After the 12th reloading I retired the cases. Normally after loading a rifle case ten times I would say I've gotten my money's worth out of it. That test did make for a long two days. If I remember correctly, Mr. Wilson was running the same test and got about the same results.

My normal reloading process is to wipe off the fired case to remove any grime and then use Hornady "One Shot" spray lube (a quick spray from all four sides and give it a few minutes to spread) before sizing and de-priming the fired the cases using a RCBS single stage press. The spray lube will cover the entire case and also allow a small portion to hit the inside of the case mouth. Then I will run the cases in a tumbler to clean off the lube (and make them look pretty ). At that point I re-prime, put the powder in, seat the bullet, and crimp all using a Dillon 550.

I've tried both Lee and RCBS dies and really have not noticed much difference between the two.

sorry to change the subject, but i have some info that may be useful about 110gr sp bullets. see below...

I posted a short re-cap and photos from a YO Ranch hunt over the past weekend in the Exotic Game section, we all used 300 HAM'Rs

cool!! i didn't even know there were any other sub-forums in this place

My shooting/hunting buddy Jeremy's 15yr old son did some HAMR'IN this am with the Hornady 135FTX. Two were DRT kills and the third one only ran 10yds.

That is RIGHT in so many ways.

I took two hogs last night with the HAM’R. One nice sized boar and one little one. 150gr SST dropped both them both. Shot the guts out of the little one!

Would really like it if this forum had a "like" button.

Successful morning !!!

I left camp at 7:30 and had the 11pt on the ground by 7:35 !!! Then the 10pt by 8:45

11pt, 160yd shot, 300 HAM'R, 135gr FTX, DRT

10pt, 90yd shot, 300 HAM'R, 135gr FTX, lung shot, ran 30yds

Joyce and I saw a buck bigger than either of these last night at 7:10pm, but he was too far and it was too close to dark to take the shot.

Wow, great morning. How wide is the 11 pt.? Good looking buck.

18"

For some reason I was under impression that powder charges should be use reduced (5%?) for converted brass.
Today, I briefed through all available information and couldn't find any mention of the above.
What I did find (thanks to information by @ShadowFast1, cpt80 and @djones) is that converted LC brass have slightly thicker neck walls and more volume which, theoretically, should make it functionally comparable to factory 300hamr brass.
I would guess that average pressure will be slightly lower and pressure peak will be slightly shifted due to narrower neck passage which at worst might result in minuscule velocity change.

So, do we need to reduce the load for converted brass, assuming it has similar neck thickness and volume? If yes what would be the reasoning?

Let's take LC cases for example since a fireformed 300 HAM'R case made from a LC case will have almost the same powder capacity as a new Sig mfg 300 HAM'R case and slightly more than a Starline mfg 300 HAM'R case.

A case formed from a new or fired LC case will have less powder capacity than factory produced 300 HAM'R cases BEFORE fireforming since the area below the neck is smaller in diameter than it will be AFTER fireforming, thus a reduction in powder is recommended. However after fireforming there is basically no difference between a LC 5.56 derived case or Sig factory 300 HAM'R case. Also keep in mind that nickel plated cases generate more velocity/pressure than a standard brass case and adjust your powder charge accordingly.

Always watch for pressure signs to determine if a load is at safe pressure levels, such as:

Abnormally high velocity compared to published load data. Published data is from a 18" bbl, so adjust +/- 12fps per inch for different bbl lengths and keep in mind that velocities recorded with a LabRadar will normally be 18-20fps faster than those recorded with a conventional chronograph.

Flattened and/or cratered CCI450 or CCI41 primers, these primers are hard and normally don't deform at safe pressure levels.

Case expansion approx .300" up from the base. Sizing often doesn't fully remove this expansion, so if a sized case won't freely drop in/out of your case gage the load was too hot.

Thank you BIll.
The information is extremely helpful!

P.S.
The document with load data I've downloaded from your site (Wilson-Combat-300-HAMR-LOAD-DATA-5-20F1.pdf) says that the velocities are for 16.25", is there another/newer source of load data?

Sorry, I forgot we adjusted the velocities after SAAMI acceptance with a 16.25" bbl

not sure what info i shared, but i've been known to stretch the truth... A LOT!! what is true, however, is that i've listened to people who had me loading up to where i shouldn't have and i've blown necks off, stretched case webs, destroyed my first set of loading dies, and stuck cases and necks in the barrel to where i had to put the upper in the freezer to get the brass to shrink enough to remove. so please, don't take any advice from me. about the only thing that i haven't damaged is the rifle, and i'm really not quite sure how it survived! now i only listen to b.w., well most of the time anyway. the only thing i stray from is his bullet choice. i'm not sure he has the confidence i do in his 110gr loads.

oops, wrong vid. updated. but i didn't shoot quite as well on this herd. half of them ran behind and made me a little nervous

Yeah, you sort of sucked that one up in the beginning but you got your legs under you and finished strong

Thanks for sharing...I thought you were immortal before now.

Back in June you've posted case volume data measured by DavidK.
And like you I would be very careful about posted loads unless those are from official source or can be at least confirmed by simulation software.

BTW, which 110gr bullet do you like? Is it Barnes TSX?

judd, even the pros miss the cut once in a while... well... expect for me

gene, ah yes, i was relaying DK's info. he's an engineer so i trust him to take a measurement. he cant shoot for crap, but he can read a scale.
i'm shooting the 110gr hornady sp. they seem to be out of stock everywhere but i've got some 110gr and 135 gr sierra hollow points coming in. i think some 125 gr sierra pro hunters too. the tsx tend to ricochet but i'll get some if it comes down to it.
