Fixed.

Fireball2,

I discovered my son-in-law is a natural born bear hunter. He sees so many he doesn't even hunt them anymore. Maybe I should get him together with you and me.

.450 vs .468. You ain't that good....

We need to take a day in the mountains with your son in law, some sammiches, Gatorade, optics, and rifles!

I'm just starting to work with some 150's in my 284 with R17. Initial shots hinted at very good accuracy though I've some work to do as I'd like to hit 2850-2900 fps.

The 140-gr TTSX is stellar in this rifle both accuracy-wise and in velocity with R17 but on some longer range deer kills there was less (as in hardly any) expansion than desired. Hence, trying another bullet. These looked like a good bet and are only a "smidgen" longer than the mono- 140's.

I don't think the velocity issue as described will be one in this cartridge.

I have got chrono readings with Re17 [without pressure sign] that were so high, I would bet big money it was not possible:
270 130 gr NBT moly 3.34" 57.7 gr Re17, 22" barrel measures 3129, 3228, and 3228 fps.

That rifle with 4895 and that bullet is usually 2875 fps.

But once I calculate the powder charge reduction safety margin I need with Re17 wild temperature coefficient, all gains are lost.

Clark, those are certainly high numbers but not outrageously so. IIRC, and someone may correct me, but back in the 50's-60's an outdoor writer (JOC ?) mentioned filling the 270 case with H4831 and under a 130-grain for 3100 fps+. And again if memory serves with a 22" barrel.

A couple weeks ago I popped the top on a still-sealed cardboard can of mil-surp H4831 and went up to 62 grains with the 130-grain Hornady Interlock Spire Point in a 22" barrel Winchester Model 70 Classic. Average velocity was 3159 fps, without any moly on the bullets, and I could lift the bolt handle easily with the little finger of my right hand.

How old is that powder?

It's World War II powder for 20mm cannons. It was either retrieved from broken-down 20mm rounds, or powder that hadn't been loaded yet by the end of the war. Hodgdon bought tons of it and sold it as H4831 until they ran out in the early 1970's. So it's around 70 years old.

Dang, that's crazy.

I have several pounds that I bought back in the '60's, and it was surplus back then. It still performs as well as it ever did. It's good stuff.

They should be perfect for folks shooting deer with the .300 AAC blackout.

That is the bullet that I have used in various 270s to kill a mini ark full of deer. One year I actually killed 17 with it,from under 50 yards to nearly 400. None of the 17 took a step,no not one.

Now days such bullets are very unfashionable,flat base,cup in core,nonbonded with a less than ideal ballistic coeffecient.But they often are more accurate and generally can be loaded to higher velocity than the modern uberwunder bullets.

And they kill stuff really quickly because they do tend lose some of their original weight.

The GMX (BC .450) velocity gains and accuracy eclipse the LRX BC .468) marginal BC advantage. My .260 shoots the GMX at 2910, vs the LRX at 2850. Yes on paper the LRX has less wind drift, but for hunting applications, 120 GMX shoot flatter and more importantly, is more accurate at distance.

John: Let me know if you can spare a few pounds. That Mil-Surp 4831 is all we ran in our .270's up until a couple of years ago when we ran out. It has no equal in the .270 with 130 pills.

I used to buy that same powder from the old Buttreys Grocery store in Bozeman, Montana back in the late 60's in bulk paper bags for .67 cents a pound. We put in Ball canning jars to store it. Talk about the "good old days".....grin!

1966: thereabouts
Hamburger ~$.25

Fries ~$.25

Tall malted ~$.25

Gas ~$.25 gal

MS H4831 ~$.67 lb

Those WERE good days. 😊

Yep.

Still had some of those bags until recently when they got so brittle, my thumb would about poke thru the side of a bag, just handling it. I transferred everything into empty powder cans, now labeled with a Magic Marker.

The powder still smells good, looks good and shoots good. No dust or evidence of deterioration.

A friend talked about buying a 100lb keg and splitting it with his shooting buddy in the '60's, he said it ended up costing about 30 cents a pound. When the delivery truck arrived the driver wouldn't unload it (fearing it would "blow everyone up") so they wheeled it off the truck themselves. Good times.
