.308 Win 16" Covert Barrel 1/8 twist
-
Hi guys, I am going to development some loads for this barrel. I plan on using H4895 with 175 gr SMK's and Federal 210M primers. Have any of you had success with this combination of ingredients? Thanks in advance.

I don’t have experience with a barrel that short. My 308 barrel is 22” and I haven’t tried anything but varget in it.
I would try it and see what it does. Add powder slowly until you see pressure and see if you get the velocity you want.
Is this for hunting?

My 308 has a 16" tube however it has a slower twist so I'm not much help with anything over 150 grains. I have used 4895 before I'll see what I have in my load book for this rifle. It is a bolt rifle and the barrel came off of Remington Sendero and was rethreaded for my action. You might get some impressive muzzle flash with the short barrel.

I have a 24" barrel in 8.5twist for a .308. I run imr4064 with 195tmk and 175 smk , only powder I use in my .308's. Off top of my head I think 42.1gr with 175 and 40.6gr with 195. Can double check tonight if needed.

H4895 is one of the go-to powders for 308. I think you'll likely have success. If not, Varget is a good place to try.

Both for long range target shooting and hunting as well. Thanks

Thanks. I have 4064 as well, so if I don't like the results with 4895, I will try it next.
