tikka 270 barnes triple shock recipes
 

was wondering if anyone is hand loading barnes triple shock 130 grain for the 270.Any help be appreciated.

57-60 gr of H4831. The end.

Suggest you try a more efficient powder .. like Ramshot Hunter or H-100 V

Use the 110 with R17.

Oh, I have. You couldn’t give me any more 100v and good luck finding Ramshot Hunter.

But, the OP can experiment to his hearts content. But I know where I would start.

One of the 4350's is what I'd load with a 130 gr bullet.

Those were only suggestions for the OP Chuck. Not intended to upset you. RL 17 would would also be a good choice with that bullet. Just about anything but H4831 unless you like compressed loads and unburnt powder. IMHO

Unburned powder?

I load for my buddy's 270 with the 130 TSX bullets with a similar load to Chuck's other than it's with the IMR variety of 4831. I can't remember the charge weight off the top of my head, but it chrony's at about 3050 fps out of a 22" Browning A-Bolt.

I’m curious if someone has a newer or newest version of Nosler’s reloading manual that can take a picture of that cartridge and billet page and post it. I don’t have access to one but I’m willing to bet I know what they recommend.

Newest Nosler Data is available on line for almost all cartridges.

Here is the actual Barnes load data inc case you are interested.

I always liked 4831 SSC in the 270 with 130s and that is what we loaded for many years. If we could find 4350 in SSC would have tried that but the 4831 was much easier to come by. Lately we have also been using H 100-V in them and it works great too. Same velocity, lower pressure, low SD and great accuracy.

Yes, unburned powder.. unless you are using a 36 " barrel you will be spewing about 5% of your powder out of the Muzzle.

I wouldn't use a Barnes bullet to begin with. With a 26" barrel I use IMR4831. With a 22" barrel IMR4350.

Are you making this stuff up on purpose just to get a rise out of me?

Both of these powders would be burned completely in an 18” barrel.

You Thinkthey should be completely burned. Reality indicates that your thoughts are wrong. Carry on with whatever you think Chuck. It works for you.

“One of the most frequently
encountered misconceptions
in handloading is that
a charge of smokeless powder is still
burning when the bullet (or shot
charge) exits the muzzle. As “evidence,”
many shooters cite the muzzle
flash, especially visible in dim
light. Nope, that ain’t burning
powder. Instead it’s the hot gas produced
by burned powder, re-igniting
once it strikes the oxygen in the
atmosphere.
Instead, almost all smokeless powder
burns within a short distance in
front of the cartridge. The exact
point varies with the powder’s burning
rate, the cartridge, the projectile
etc. But even in huge “magnum”
rifle cartridge, over 99% of the
powder is burned burned within 4-5 inches
of bullet travel.“

John Barsness

Read it as you wish. Smokless powder supplies it's own oxygen, ceated by the potassium nitrate in the powder formula. This leaves a finite amount of Oxygen available inside the bore from the initial powder charge. Once Burnt,... and I dont think powder or gas can be re-ignited once it has been burned.. or can it ?
Upon exiting the muzzle, the unburned hot powder receives a new oxygen source from the atmosphere and completes the burn.

As is the case with the 270 /h4831 example, 95 %. of the powder has been consumed just short of 14" in the bore. John Barnsness notwithstanding.

All the cool kids are using RL 26 now anyway. Efficiency notwithstanding.

Why not. It does as well or better better than H4831 in the .270 /130 scene doesn't it!

What percentage better?

H 4831
chge 63.0 gr
case fill 114.0%
Pressure 65000 psi
MV 3384
Powder burn 94.50 %


RL26
Chge 64.0 gr
Case fill 104.6
Pressure 55000psi
MV 3376
Powder burn 98.94 %

24" Bbl / case cap H2o = 67.0 gr

I don't know about you, but I'll take the 10K less pressure any day

Salavee, one question. Have you ever opened a real bottle of RL26 in your life?

I am not sure if I can get those velocities out of 270 WSM .
And we are talking 270 WIN here.
Are you sure those numbers are right?

57-60 gr of H4831. The end.

It really is that simple. I’ve never met a 270 that didn’t like that combo. But of course I’ve nowh near met them all.

My experience also

As a matter of fact, I have 4 lbs here. Do you need some ?
