I am wondering how much the length of the TSX will effect the loading in the 500 AR. Will the TSX take up to much powder space?

thanks

Going to go do family Christmas stuff today but can take a measurement of the bullet vs the case later tonight or in the morning and post back here unless one of the other 500 AccRel owners beats me to it. I plan on using mostly solids with mine and feal very comfortable with powder capacity.
Rodney.

It has a significant impact on .500 A2 case capacity, so I'd imagine the effect will be similar with the .500 AR. It's a really big bullet.

quickload says 2175 for the XLC -- I don't ahve any TSX on hand to do actual load dev work on

I was hoping for a 570gr in the 2200 to 2250 range with mild pressure. The TSX might not let me get there. I am not familiar with many other bullet brands, what are some other GOOD cape buff options?

Tanz,

The TSX bullet is 1.562" long so it will consume a considerable amount of case volume. In the 500 A Square, which is considerably larger than the 500 AR, this amounts to approximately 20 grains of powder over a Woodleigh which is roughly 0.25" to 0.3" shorter.

For cape buffalo I recommend Woodleighs, preferably their PSP. They simply work well.

The "considerable" difference is 9 gr , ... 7.25%.. and it fits in the standard length mag .. to put it in perspective, the 500 jeffe is 10 grains larger than the 500a2 .

However, the comparison is about the .495 a2 vs the 500AccRel -- they are very close in capacity, about 1%, one is belted, one isn't.

And, for once, I agree with Scott .. wood psp 600gr bullets work GREAT

I will look into the Woodleighs. Are there any other bullet brands I should look into? With the TSX I am comfortable not using solids for backup shots, but will the woodleighs give that same kind of penetration?

thx for the help

Jeff,

I will give you than 9gr ain't truly "considerable", but with the TSX bullet even the 500A2 doesn't have enough volume (that was my point anway). So the AR case will be even more handicapped due to it's smaller case volume.

What have you used the 600gr Woodleigh PSP on?

An old picture I scanned in tonight showing the effectiveness of the 535gr Woodleigh. The rifle is a 500 A Square magnum. Shooting 535gr Woodleigh SN at a muzzle velocity of 2350 fps. The bull was dead right there. You can see the entrance wound on the left hand shoulder of the buff. The bullet was recovered from under the off side hide.



Nothing quite as convenient as getting them on the "road".

I've got the opposite question using the 570g TSX in my 500 Jeffery. I'm seating mine out to an COAL of 3.73 (third groove from the top). I think I'm leaving too much case capacity since the A Square call for 101g of H4895 giving 2303 fps, and I'm getting almost 200 fps less than that. I'm using Rem 9 1/2 M primers which are supposed to be on the cold side too so that may be a factor. I'm going to chrony my loads today if I can wake up the older son to go shooting. If they're consistent with the last time (just ove 2100 fps), I'm going to switch primers first, then try seating a groove deeper (.10"). 2300 fps with a 570g TSX seems like a good number for the 500 Jeffery.

Chuck,

I got around 2190 fps with the 570gr TSX in the 500 A2 using 91gr of IMR3031 at a COL of 3.67", which was a fairly compressed load (say 103% to 104% load density). I was using CCI 250 primers. I wouldn't think that you would need that much more 4895. In the 500 AHR I got 2255 fps with the 570gr Woodleigh using 103gr of IMR4895 COL was 3.67" and case fill almost needed a filler say ~ 92%. Again that was done with CCI 250 primers. I have never used the Remington primers you are, sorry to be of no help there.

In my experience the TSX give higher velocity for a given powder charge than Woodleigh or Hornady bullets. So it would seem to me that either your particular TSX are undersized, or you got a slow lot of H4895 (if the problem doesn't lie with the primers).

In smaller cases, ie 300 Win mag, 30-06, 308, and such it is has been my experience that the weaker primers (CCI200 and Fed 210) gave higher velocities than the stronger primers (CCI250 and Fed 215). I have never tried this experiment on the large cases (don't have that a set of gonads, sorry).

Good luck.

ScottS: What make of rifle do you have in .500 A2?

Nice buff btw!

Ian,

First, thank you! That was my first (best) attempt at fixing a Ruger RSM. The rifle is an early Ruger RSM which was rebored, with a recoil plate (Remington, Savage, Kimber, etc) between barrel and action, and a second lug dovetailed and soldered into the rib on the bottom of the barrel (the Rugers actually have two ribs the nice one you see an a second on inletted into the stock which has been somewhat butchered, at least the old ones do). It was sold a number of years ago, and since then I have built another on a 1993 416 Rigby I have had since new and shot the barrel out of (I forgot you cannot do that on a big bore or even a heavy medium bore ).

I hope you and your's are having a very Merry Christmas, and I hope a prosperous and Happy New Year!

By the way, that isn't even my buff, but a charge I had to stop after the hunter of "record" was charged, missed, and I don't know what but didn't fire a second shot. I was told before hand to drop the bull if something like this happened, so when I was told shoot I did. The actual pre-hunt instruction was something like "NO screwing around, if it looks bad and I TELL YOU to shoot drop the F@#KER with ONE shot NOW!!!" The hunter of "record" was actually in the "road" about 25' from where that buff is laying when I let the Woodie fly. I was about 20 yards at ninety degrees to the road (this wasn't supposed to be my bull I was to get the BIG one which I did).

Scott thanks for the info! Awesome shot on that buffalo by the way. What a great hunt that must've been! I'm so jealous, hopefully within two or three years a cape buffalo hunt is in the cards for me.

Just got back from the range, getting just under 2100 (around 2090 fps average) fps consistently in my 500 Jeff with Jamison Brass, Rem 9 1/2M primers, 101g H4895, 570g TSX and OAL of 3.73". Since my accuracy is very good, sub .75" at 100 yards when I do my part, and I have 7 lbs of H4895 left, my plan is to try Federal 215M primers, and then just increase the powder charge until I either hit 2300 fps or see accuracy deteriorate or see pressure signs (which I don't expect to hit) since 2300 fps should be attainable under the 500 Jeffery pressure of 40,000.
