30 Herrett - Your Favorite Contender Loads?

[Magnum Mike]

As the title sez, I'm interested your favorite 30 Herrett loads that you've run in a contender. Mostly 110 grain bullets as i have a pile of Nosler 110 Tipped Varmegeddon bullets to run in it.

I'm working on my recent Super 14 30 Herrett purchase, last night i finished my first 50+ cases, and promptly let them run in the tumbler all night as my countdown timer didn't survive the move year before last. The cases were Winchester 30-30 that i had bumped up to 375 to use in my stainless S14 375 Winchester BUT they did not expand in a manner that i was happy with so last night they got chopped. I was able to source 250 375 Win cases, from Starline a couple weeks back so i'm good in that department. Currently waiting on Starline to make a run of the 32 Win Spl cases that i have backordered to make more 30 Herretts.

Funny side note, my HF mini cop saw has converted at least 10k of 5.56 to 300BLK. I can't remember how many blade changes I've made with it, but it's been several. I try to run it fairly easy, not like you see people running them on utube as fast as the can. I started chopping these cases last night and the blade was so dull it kept stalling! LOL!! So, couldn't find the spares (i know the saw's box would have made the move and that's where the spare blades were stored), so off to HF i went to get another pack of blades. Today Jules tells me that i could have gotten a replacement countdown timer there also! I looked around but obviously walked right past it.

All that to say, please share you 110 grain, or there about, loads with me. Thanks in advance!!

In recent decades, my 30 Herrett shooting has all been IHMSA focused.

Back many decades ago, I remember my 10" (bull with the permanent front sight) was real happy with H4198 and a 110 gr bullet.

I am sure it was either a Sierra or Hornady bullet, so my load data would be of limited use for you.

I did a Quickload table with your bullet so you can compare potential velocities and fill percentages of different powders.

Just wondering….why run that table at such a low pressure? Seems like 40-45000 psi is closer to normal max contender pressures?? Do you agree?

Just wondering….why run that table at such a low pressure? Seems like 40-45000 psi is closer to normal max contender pressures?? Do you agree?

People have stretched Contender frames by pushing the 30 Herrett to hard. In some specific conditions, 45,000 psi might be ok, but I am not completely convinced. I have reasons to believe that there are more inputs into frame stress than just the chamber pressure and case diameter (meaning: what is ok in one gun may not be ok in a different gun). Additionally, I do not have a lot of confidence that the average reloader is going to be able to look at fired brass and tell the difference between a 40,000 psi load and a 47,000 psi load. As such, "working up a load" an relying on "pressure signs" is putting a very nice out of production gun "at risk".

Quickload says that 40,000 psi is max rated. When you run this kind of table, it defaults to a lower pressure, in this case it was 34898 psi. I anticipated potential use of the Quickload table with no calibrations efforts (actual case capacities, actual seating depths, Powder burn rate factor (Ba) tweeked to match chrono results). As such, the actual pressures for a load at the listed charges could be a good deal above the predicted values.

Given all of the above, leaving the max pressure for the table at the default value seemed prudent.

Thank you!!

So I'm comparing data from Hornady and Hodgdon using IMR4198. Hornady lists a max charge with a Hornady 110SP as 28.4 where as Hodgdon lists the max, with the same bullet, as 24.3! 4.1 grains of powder is a huge difference, IMHO. Anyone have experience with this powder and a similar bullet that can provide some feedback. I believe I'll work up to the Hodgdon max and, depending on those results, go from there...

Seems to me that the Barnes TAC 110's are supposed to be about perfect in that chambering.

This is a varmint load, not a deer getter.

I've loaded up my first test ammo with 24.3 as max. Once i see how those look, i may work up toward Hornady's max BUT the cases are really gonna have to open up to get that much I4198 in the case! LOL!

If you look at the 4198 listings in the Quickload table, you will see neither is at 100% load density. One big variability can be case capacity.

To get more accurate predictions from Quickload take a fired case and measure actual length and determine case capacity (how many grains of water it will hold). You also should measure actual bullet length. Input this info. Then double check that that a load with a predicted 100% fill will have just enough uncompressed powder in the case such that there will be zero airspace below a seated bullet.

Take a starting load and get some chrono data (both velocity and distance from muzzle for the speed are needed). Input all of the above and then adjust the powder burn rate factor until the prediction matches the data. At this point, your confidence in the pressure predictions is probably good to within maybe 5% for that batch of powder.

As a point of curiosity, you see a big difference between IMR4198 and H4198 for predicted velocity even though the max charges are nearly the same. However, most burn rate charts show them to be nearly the same powder.

i can start making 30 Herrett cases from 30-30 Starline cases. i bought 500 30-30 cases for my 35/30-30, but i still have 400 cases. i bought a 10" Contender barrel that i should have next week. altho i am going to do cast boolits, probably 150gr fnhp gc (12+/-bhn), i won't pass up a jacketed bullet load. the 30 Herrett is new to me, so i'll most likely have questions.

i still have the orignal HF mini chop saw blade (i have 2 or 3 blades that are replacements), i form alot of '06 brass to 6.5x55, 7x57, 8x57, 9.3x57 and 7.65x53. i am no where near 10,000 cases, i think i've cut 1000 - 1250 cases? you right about u tubers, they do run them fast!!! i must be a old man on a walker because i cut the cases slowly.

Mike, I sent you a PM on the SP site, I cant figure out how to here, I do have some brass for that barrel if you need it (SEM)
