Default For .308 Winchester?

Out of several powders in the 'middle' range, I find IMR 4985 works very well for me. I shoot the same ammo in both a Garand (yes, in .308 Win) and a Remington 700 bolt gun.

With 174 grain match bullets (G. I. surplus from where I bought them) over 41.0 grains of IMR 4895 I get excellent results. (That's a top end load, but not over what my book shows as 'do not exceed'.)

The group shown measures just under two inches and as the notation shows, was fired at 285 yards at a local match in front of witnesses. The shot on the far left was from the next target and not mine. Fired from a bench rest, not offhand or prone. Yeah, I'm kind of bragging.

90% of my .308 loads are cast bullets.

In my 700VS,factory loooooooooooong throat.....I quit looking for a bullet,220's weren't getting anywhere near the rifling.So,if loading for Deer....give me a handful of Sierra 150 plainbase'd Gamekings and some Varget.Loaded to book "max".

I've never found anything better than H335 in the .308.

Just curious. Do you trickle your powder to scale or just dump it by volume.

VV N550 will give you some screaming velocity at less than screaming pressures. Gotta love a good double based powder.

I set the measure with a Redding scale, and dump charges from the measure into the case.

I even dump with large extruded powders.

I've done rather extensive testing with super accurate varmint and target rifles, and I can tell no difference in accuracy between dumped charges and hand weighed charges.

I guess that's why the bench rest boys dump from the measure. Many believe that volumetric consistency is more important than weight consistency.

Thank you. I was told this, but was skeptical. I have received my parts for dumping from Dillon and am set to experiment. I use Varget for my .308, but will give your powder a try too.

I think you'll be pleased with it. The first "batch" of 335 that I bought was 100 pounds. It cost me $135. this was MilSurp.

A week later, I called Hodgdon for another 100 pounds, and they were sold out.

It seems that some joker had won a world bench rest championship shooting a .308 with H335. They sold out of several million pounds in 48 hours.

I have tried many different powders for loading .308, for use in both my bolt-action Savage and NM M1A. I use the 168-grain bullets for all of my loads. I can tell you that overall I have had the best luck with IMR4064 hands down. It has produced very good loads with great consistency. I have also had good results with IMR4895 and Varget using both rifles. IMR3031 produced a good target load for my M1A. H335 is great for my 30-30 loads but I have not tried it it for .308.

Those are all excellent powders. For my taste, I prefer to stick with spherical powders over extruded powders whenever possible, mostly because they flow through the measure so much more smoothly.

I think you'll find that H335, and BlC#2 will both work extremely well in your 308s.
