Hi
I'm trying to find the best possible powder for my 6mm Rem.
Can a good soul lookup in Quickload for good prospects please

6mm Remington
26 inch barrel
1 in 10" rifling
Hornady brass: 57.4 grain of water

Right now I am shooting Berger 80g FB Varmint # 24321
Bullet length: 0.927"
COAL: 2.835

But I would also like to find out for the Hornady V-Max 87g # 22440
Bullet lenght: 1.037"

Quickload gave the classic near 100% density at near Maximum pressure indicating excellent efficiency. The warning is real. Work up toward that load and your very first signs of pressure indicates where your firearm and load vary from the Quickload prediction. Back off safely from the first sign of pressure for a repeatedly safe load. I back off slightly more than my margin of error. You will have to decide. 2% charge weight reduction from first pressure sign works for me but YOU set a value YOU are safe with.

Thank you Onondaga.
I know Quickload is for real. Their max loads are most always a few grains above the lawyers loads...
no worries, I will be safe.

Stef,
it would be extraordinarily odd if your rifle and bullet you list don't like Hodgdon Varget really well somewhere in charge. I always recommend a traditional long range ladder test and I have recommended it to you personally before to find the charge with the broadest sweet spot in 20 shots at 1,000 yards. That really works too.

You ask for the best powder for 80 and 87 grain. I'm surprised that quick load can't vary the barrel length to 26 like your 6 mm.

But in years past i got away from large rod type powder like varget. It just doesn't meter well and modern powders get higher Velocity with less pressure. My 80 grains were right at 3500 fps and 87's at 3400

When Hodgdon HYBRID 100 came out. I did testing from 75 gr to 100 grain Then when Hodgdon SUPERFORMANCE came out I used it for all my 100's and 105's

I only use 80 and 87 as my varmint rounds with H100V and SUPERFORMANCE for all my 100's for many years I've actually switch to r-26 for all my 100 grain.

The cases are so small that magnum primers are not required. I don't use a magnum primer unless I'm shooting a real magnum which means exceeding 80 grains of powder

I use a RCBS powder measure and Varget sucks crunching and cutting through the long rod type powder. All these new ball type powders just pour through like water.

the 80 and 87 grain really Like the H100. right from Hodgdon reloading online site using a 24 inch barrel. My 80 grain I toned down to 3500 fps sweet spot and 87 gr to 3400.

I need to do some test with superformance and 87 grain. i would probably start right at 50 grains and work up in .3 increments. In my load notes H414 showed some good velocity with 80 grain I just never pursued it. Varget is something that used years ago with light weight .243 dia bullets 70, 72, &75 when it ran out I never bought it again. I just don't like fast for the caliber powders. You use premium gas in a hot rod

The 6 MM Remington is a great round, to bad it has been all but forgotten for the most part.

I agree... But good things come and go and sometimes come back again finding new life in a specific niche.

284 Winchester is a good example.
When it arrived, some said it will make the 280rem and 270win obsolete.
The 284 came and went. Fast forward a many decades...
In the past 10 years the 284 Win has been the most popular F-class 1000 yard cartridge.


Treat that trigger like it’s your first date, not like you’ve been married to it for 20 years.

From both an accuracy and velocity standpoint I found IMR 4350 to be an excellent powder in this round for about 3 decades before Varget and Quickload were put on the market - in 3 different rifles as well as the similar .243 in 2 different rifles.

I dispense my powder with an old Autoscale and it has no difficulty at all dealing with the even larger grains of IMR4350.

36 Years ago, before I sold my 6mm Rem, I used 45 gr of IMR4350 and 80 gr Speer SP at 3580 fps chronoed in 24" bbl. Was awesome on rock chucks in Idaho. I had to trickle every load. I suspect the H100V would be an excellent powder as I've found it mirrors 4350 in pressure, accuracy and velocity. And as Budlight said it meters very smoothly with no need to trickle. I don't know about the Superformance powder.
