    I plan to start reloading for .308 hopefully around Christmas and I am starting to research powders and load recipies. The main purpose of my loads will be whitetail deer hunting (150-300lb here in Maine and 10-300yards possible range) with some paper punching as well. I plan to buy 150gr and 165gr Sierra Soft Point Boat Tail Bullets, as these weights have worked well in factory loads for my gun. I plan to load in once fired (from my gun) federal brass, likely with CCI or possibly federal primers. My question on powders: I would like to try H335 as I have heard, being a ball powder, it meters much better than stick powders, but I seem to see many more references to Varget, h4895 and imr4895. I have also looked at prices and h335 seems cheaper. What are the negatives of h335 that I seem to be missing (if any)? Also any input you feel would be relevant to these specific loads (including tried load data) would be much appreciated.

    This is what I pulled from Hodgdon's site:

    165 GR. HDY SP Hodgdon H335 .308" 2.750"
    Gr- Fps- Pressure-
    Start: 39.0 2432 44,500 CUP
    Max: 42.0 2608 49,100 CUP

    150 GR. NOS E-TIP Hodgdon H335 .308" 2.800"
    Start: 40.4 2551 46,500 PSI
    Max: 43.4 2790 59,100 PSI

    150 GR. NOS BT Hodgdon H335 .308" 2.800"
    Start: 41.0 2619 42,600 CUP
    Max: 44.0 2787 51,200 CUP

    Only thing I've found in my research so far is that H335 has a faster burn rate than the others and seems to take up less volume. My concerns with those facts are will it be harder to find a 'pet' load because its faster, will the accuracy nodes be smaller/thinner? With it taking up less volume I know I'll have to be more vigilant about not over charging (I don't know if it would be possible to double charge?). Is there a possibility of reduced accuracy from not filling the case?

    Sorry for the overload of newbie questions.

    Thanks in advance!

    Among the gents I shoot with on a regular basis at range we're members, general consenses on their preferred powder for reloading 308 is Varget powder. Not sure, but believe they also prefer Sierra Game Kings 165gr with the Varget. They hunt, I don't. Can't recall anyone ever mentioning using H335 for .308, or any other cartridge for that matter. I have used Varget with good success in a .308, but pretty much limit max grain of my bullets to 155gr.

    I prefer to use Ramshot TAC powder for my .308 target shooting. TAC's burn rate is between that of H335 and Varget. Check the Hodgdon burnrate chart, probably will not find Ramshot TAC on it, but IMR 8208 is shown and TAC's burnrate is darn close to it.

    You should find the Ramshot powders to be lower priced than Hodgdons and all four of the Ramshot rifle powders I use on a fairly regular basis in around 7 various cartridges, from .223 to 30-06, are a ball type powder that meters great and seems to be clean burning to me.

    I have used Varget for years. The nice thing that I think you will appreciate in Maine is it's very consistent no matter the temp. It fills the case more (which is what you're looking for) and you can use it in multiple calibers.

    the siera's shoot good for me. ive used h335 for my .223 but not .308. it does meter well. for my .308 like IMR 3031.
    my main 2 loads are sierra HPBT for chucks, and hornady SP for deer both the 150gr variety. with 42gr of IMR 3031

    Your question assumes there is repaeatable predictability to loading ammo. I do not believe there is. H335 is a good choice for the 308, if not ideal. I use BlC2 and 748 in most of my rifle loads, but I am loading (in most of them) for reliability and combat effectiveness. The only real way to find out the answer is to load and test the ammo in your gun.

    RL 15 is a good choice as is H335 and Varget. Many powders that work in the 223/556 also work great in the 308/762.

    I use a lot of H335 in 223 caliber loads,but have never tried it in 308.
    Varget,Reloader 15 and IMR XBR8208 are excellent 308 powders.My best accuracy loads come with Reloader 15.
     
  11. 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.
