6xc best powders for lite bullets

[steelhead king]

I'm building 6xc with a 12 twist barrel for varmint hunting. I'm planning on us 60-80 grain bullets. There doesn't seem to be much data out there for the lighter weight bullets. Let me know what you guys are using, or point me in the right direction. Thanks,

There are many other powders that will work.

I love 80 gr Berger FB Varmint... They're stupid accurate.

 

[Zero333]

Let me know what bullets you're gonna wanna shoot and what powders you have on hand and I can see if I have data for it.

 

[steelhead king]

I will. I was also planning on buying powder if I can find what I need.

Before my XC, I was getting excellent results with IMR 4064 and 4895 with 65gn v-max bullets from a 243 Win. Both powders performed great surpassing my expectations and gave me a nice, forgiving powder charge window to work with. Best loads were with maximum charges.

Tried some RL-15.5 in my 6-250AI yesterday with 80 Nos BT with very interesting results. If you have some try it starting around 41 grs with a 75 - 80 gr bullet.

I used 34.5 4895 with 70 gr bullets. Since there is no 4895, I would start with the same load with N140. I have also used 36.5 H4350.

I've had a 10tw 6xc for varmint and predator hunting for almost 10 years now. Great cartridge IMHO.

For 68-75 gr bullets I've used R15, 4064, and 4895. Just recently I tried some Staball Match in it wth a 70gr that showed some promise also.

For 80's -85gr I've used 4064, R-15, AA2700, and WW760. I liked the 2700 real well with those bullets.

It's an easy cartridge to load for in my experience with it. Enjoy. WD

Although high, Cabela’s is still showing H4895 in stock.https://www.cabelas.com/shop/en/hod...5&bc_lcid=t5006366862778368lw5669266929524736

2nd on the RL15, with 75gr vmaxs. They did very good for me.

Steelhead King,
I had a 1:10 6xc I used H4350 from 65-95 grain Bullets and it shot extremely well but as others stated many powders work well it’s a easy and forgiving cartridge to tune

Thank you.

Varget has been great with 85 gr. SGK in mine. Good velocity and accuracy. I have some Ramshot BigGame
that I haven't tried but I'm thinking that should work well too.

Good luck with yours and report back. John.

In my 6XC with 85gr Sierra BTHP, These shot excellent with groups at or below .2 and 3300+ fps and this bullet has anchored every single groundhog on the spot in every cartridge I've used since 1976

Believe it or not my 6xc likes most everything some. I had to go through a bunch of different powders to find what it like the most, I never had that problem to that extent. Mine is a 1-8 twist and I finally settled on Sierra 107gr MatchKing with IMR4831, and RL19 with 108gr Berger's elite. The powders that most had great luck with the H4350, which shot good in mine but the IMR4831 & RL19 out preform it. The only problems with my loads is both powders are somewhat heat sensitive where the H4350 isn't as much. But it just goes to show every gun is different. You love your XC as they are crazy accurate and very easy to load for for sure.

I have 75 grn Sierra HP. I also have 4895.
.

H-4895 & IMR-4895 are almost the same but may differ due to lot to lot consistencies. However, with the 75 gr Sierra HP you could start at 38-39 gr and work up to 41 gr.
Load density might not be the best with this combination, but it will work and worth a try.

COAL for the 75 gr Sierra HP is fairly short at like 2.520"

 

[steelhead king]

Thank you. That is where I will start. I'm waiting on some parts so I can finish the rifle.
