.308 powder questions
 
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 use IMR XBR8208 and Alliant Reloder 15.

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.

opaww 10-14-2012 07:13 PM

I use 44.2grs of RL-15 with 165gr sierra game king and also with 168gr HPBT Hornaday match it works well for me

nitestalker 10-14-2012 07:35 PM

RL-15 in your .308.:)

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.
