6mm ammo?

Can anyone give me good advice on buying the best 6mm hunting ammo?
My barrel is a 1:10 twist and is 26" long. Was thinking about a 105 grain Berger VLD bullet? This twist lends itself best to heavier bullets like 100-108 grain.
Thanks for your feedback.

I reload for the .243 with a 1/9 twist using a 100 grain Nostler Partition. They work great with that rifle. I believe you can buy them factory made also but the price tag is up there. Sorry I cant be more help with the 1/10 twist, but I bet those or something bigger will work.

Not to rain on your parade, but a 1:10" twist will not stabilize a 105 gr Berger VLD bullet. Bergers have a 9r ogive, making the bullets very long for their weight, so you need a tighter twist to properly stabilize them. I am currently building a 6mm-06 for a customer, and I used a 1:8" twist barrel to stabilize the 105-115 gr VLDs, as recommended by Berger.

You might do well to try a few shorter bullets:
Hornady 100 gr Interbond
Sierra 100 gr SPBT
Speer 105 gr SP

Or go to the tried and true 95 gr Nosler Partition.

Depends on what you are hunting and which 6MM you have...

Before reloading I tried every thing and was never disappointed. Standard 100grain Hornady Customs stuff was probably most consistent. With that long barrel you may want to give the Hornady light mags a try. The Corelokts were great and the Winchesters shot well too but the partitions (great bullets) just didn't shoot well. It will be a trial and error thing as far as accuracy but all are very good on deer. Since reloading I went to 85 grain btsp Sierra's and love the blood trails it leaves and so far are the best I have used on deer.

I picked up a very good used .244 barrel (1-12 ) and still use it for deer. Out to 100 yards it handles Hornady 100 grain RN very well. I would think 1-10 should handle 100 grains equally well. It is a matter of experimenting for you.

Ive got an old rem classic in 6mm and it shot remington corelock factory ammo as good as any handload i worked up. It liked that bullet so much that i bought a 1000 of them years ago and its what i load in it. Ive had great luck on deer sized game with that bullet. Ive also gotten great accuracy out of the 100 grain sierra but the corelock seems to be a bit stouter and holds together a bit better on deer.

Thanks for the info:

Good info and apprceiate the feedback. I was told that the 1:10 twist was ideal for the 105 grain bullets?? Oh well, guess you learn something everyday.

Well, it is about right for the nearly defunct 105 gr ROUNDNOSE. Stabilization is governed by bullet length, not weight.
It will handle a 100 gr flatbase spitzer.
If you want to shoot a boattail, check the maker's recommendations for twist. You would have to go down to a 90 gr Berger, for example.

I use Hornady 100 grain RN and as of last fall they were still making them.
#2455 RN 1-10 sounds like a standard .243 WIN twist rate. I also have a .243 and it works O.K. with heavy or light bullets, depending on the brand. I believe you are talking about the old .244 REM like I have (1-12), because when Remington changed the .244 name to 6mm, the twist rate went to 1-9. The above post sounds right, when you go to heavier bullets you need the length. The only bullet around 100grains that will stabilize in my .244 is the Hornady 100 grain RN.

Might take a look at the Speer 90gr spitzer. That's a money bullet in a 6mm or 243 for quick kills on deer size animals. The twist is right for that weight/profile.

yeah its odd. I have a 260 with a slow twist that still shoots heavier bullets great. The rate of twist thing seems to be a more general rule of thumb then an absolute. A more-often-than- not "rule". Very interesting about the old round nose bullets. It is another old timer favorite. Though I never used them I have heard over and over they hit harder than the spitzers.

I agree with you. I think velocity has a whole lot to do with stabilization. It is not everything, but definitely has an affect on which bullet to use. You should try 160 grain RN in your .260, they really wallop a deer.
