.308 Cal. .224 Sabot Load for .30-30


May 31, 2009, 03:38 PM
I'm a newbie to this forum. Looking for some data that I have not been able to find on the net...

I have had very good experiance with the .30-30 accelerator round and decided to load my own. The recipe from E. Arthur Brown, states that a load of approx. 32 grans of IMR-4198, RX7 and S4197. Should be reduced 10% for a starting load. I didn't have any of these powders in my stock so I loaded some with H-4895. With the loading data that I have available, the H-4895 is slower burning and typically uses 5-7 grains more powder with the lighter grain bullets. So with 6 grains average, I figured it would take about 38 grains of H-4895. Minus 10% for starting load would be about 34 grains.

My load ended up being 30 grains of H4895 using a CCI-200 and a 52 grain BTHP.

I have yet to try them, I just wanted a second or third opinion. These will be shot from a Winchester pre 64 94.

Also, does anyone have data on loading an accelerator to the .300 RSAUM? E.A. Brown has data for the .300 Win. Mag. which would be the closest load to the .300 RSAUM.

It should be safe if nothing else.

A 110 bullet and 34.0 grains of H4895 is a starting load.

I would be VERY wary of downloading the .300 RSAUM with anything due to the danger of over-bore magnum pressure anomaly's.

Here is some Hodgdon H4895 reduced load data you might find of some help.

Thanks RC.....Yes, I'm just looking for a safe starting load the the lever action and I'll check velocity if the accuracy is ok. I have had very good accuracy with the factory loads. Thanks for your input.

I don't think H4895 will give you very good results. It's just to slow. Way slower than what conventional wisdom would suggest. Powders with the burn rates of H4198 or SR4795 is where I'd go. Even H4227 and Reloader 7 seem a little to slow.

I'm looking at my notes from 1997 when I played around with J&D sabots in my .30-30 (probably still have 3 or 4 hundred left). That was right before I got a chronograph, which is to bad, so I don't have any velocity data. It was also before I started using a Powley Computer so I was flyin' more by the seat of my pants and relying on what I could find in print (almost nothing) or on the Internet (which was much smaller in those days).

I was using 45gr, 50gr, and 60gr Hornady HPs. H4198 loads from 29gr to 32gr, and H4227 loads from 22gr to 23gr. All my notes say about the same thing: "100% backed out primers", "50% backed out primers", "4 of 10 primers backed out"....

At that time I thought it was because my loads were too hot. Now I know it's just the opposite. The loads were too light. It was the lack of the phenomena known as "bolt thrust" that was allowing the primers to back out.

The next year I got a chrony and did chrony some factory Remington Accelerators in my .30-30. Ave velocity was 3362fps.

Were I to do it today (and I WILL... one day) I'd start with a load of 31gr of SR4795 and a 60gr bullet (66gr with sabot) and work up. That's what my modified Powley Computer is indicating with a 3400fps mv. That sounds about right, but I'd look around for some more data points before I loaded anything and pulled the trigger. 37gr of H4198 is another load I'd try.

A couple of watch outs and suggestions. Remember to add the weight of the sabot to the weight of the bullet when you're looking at loads or plugging numbers into a program. My notes say they weight 6gr each (another source I saw said 12gr so I'd want to double check that). Until the they leave the barrel the bullet & sabbot are one projectile.

Don't put your chrony to close to your bench. The sabots fall away after about 40 feet. Otherwise a hit from a sabot could destroy your chrony (I'm on my 3rd or 4th chrony, so trust me on that one). You also don't want both the sabot and bullet both flying thru the screens. It'll mess up the velocity reading. Look for your sabots on the ground. If they've blown apart, or the petals have torn off, your velocities may be to high. If you can't find them at all, that is probably an issue too.

A well written article on sabots:

Let us know how it turns out.

Thanks Kernel, That's all good info. I'd still like to try the H4895, just wanted to make sure it would be safe to shoot with the load I came up with, in a lever action.

I have seen loads for the .300 Win Mag, that's why I was asking about the .300 RSAUM.

Welcome to THR, spitzer1017.
More than likely, H4895 will not give a good burn cycle with the light .224 sabot load.
It is also difficult to insert the bullet so that it's concentric to the bore. I've had to use a V-block with a dial indicator to manually center the bullet properly in the case. I used Rel-7 but was never impressed with the accuracy of the combo.

Anyone else have suggestions on a load using H4895?

I loaded some 55gr accelerators around 97-98 to be fired from a 14" contender and a Marlin 30AS. Keep in mind thay need to be single loaded in the lever action. I was using Accurate 2460 at the time and got 12" + groups at 100 out of the rifle but the pistol liked them a little better. Not good enough to hunt with though. Under 25 yards they were fairly accurate.
It was the only powder I had at the time and I discussed load development with Bill Falin Jr. from Accurate while he signed my Accurate manual #1. :cool: I never made it to testing with 4895 or any of the other powders I had intended to. Someday I will get to it. Sorry, not much help here.

That's o thanks for the info...

Does anyone else have any input on this sabot load? I mainly want to know if it will be safe....I've had good luck with other loads using the sabot.

30 grains of H4895 using a CCI-200 and a 52 grain BTHP.

Anyone else have any comments on a sabot load using 30 grains of H4895,CCI-200and a .224 52 grain BTHP. Just trying to get an idea of pressures. Don't want to harm my pre-64....

I ran your load through QuickLoad. It estimates a max chamber pressure of about 13600 psi, and max velocity of about 2200 fps. Seems to me it should be quite safe.

I'd be happy to send you the details so you can verify my inputs. Let me know.
