308 load with H4895


Registered Users do not see the above ad.


Been wanting to try some loads with 150 gr Game Kings but the Sierra manual does not have load data for H4895, only IMR. i like the "H" due to temp condition (supposed to be) and have loaded the 150 above but only to 41.0 gr. does anyone have a suggested max load for this bullet and powder using Win Brass, BR2 or 210M, case trim to 2.005, seating depth i have played with at manual spec of 2.750 out to 2.790.

i plan on trying the OCW in hopes of finding a good optimum starting point to tweak but need to know a max load.

if there is another powder better, suggestions welcome. also have the 165gr GKg and by searching a lot of folks are using 46 gr of Varget, which i have, but havent gone above 44.0 with no pressure signs. just scared to go that high in charge i guess.

thanks,
Ron

Hi Ron, welcome to the forum.

Recently was working loads for my .308 with H4895, 150GKs and WLR primers in Win cases. Hodgdon's data which lists 46.0 grains as max with a Sierra 155 grain HPBT bullet. Their load recipe called for Win cases and Fed 210M primers and 2.775 COL.

My rifle shot the 150GKs best with BLC2 and IMR4064.

Sierra says 43.0 grains of Varget is maximum for their 165 grain pills. My rifle will take quite a bit more without pressure signs but the accuracy wasn't there with Varget.

That load should be OK with a 150 gr. since the .308 runs at a higher pressure level. I use the same charge in my .30-06 with 168 gr. for the M1. Its well below the top pressure wise.

There shouldn't be any problem using the same charge of H4895 as you list with IMR-4895. They are seldom more than a grain or two apart one way or the other. Hornady #9 shows a max of 44.0 with H4895, 46.0 with IMR-4895 for standard .308. There is only half a grain difference in the service rifle section for the .308. They also mention Varget as giving top performance with all weights.

MontyF,

i saw the 155 Mk at 46 gr on Hodgdon web page but figure the jacket may be thinner than the gamekings, my assumption here. i may just use about 44.0 as a max and by using the OCW method going one increment over that and then watch for pressure signs.

i havent tried BLC2 yet but have loaded with IMR 4064 a bit and seems a little sensitive in my 308. Varget for the 165 with a 42.5 load does very well. not a speedy load but accurate.

i know have 2 308's, one rem 700 and one vanguard, that i replaced barrels on. both reamed with 95 Palma reamer, 1:12 twist shilen, 24". the rem shoots very good but want to work some other bullet loads and try the OCW method. the vanguard hasnt been fired yet but plan to load some this evening for range time tomorrow.

Rifter,

i saw that as well in the Hornady manual but not figured that was for their bullet construction. i have loaded a good bit with Varget and produces good results, RE15 does as well. just in the mood to try something different. i may try loading some test for pressure rounds with Varget up to the 45/46 see watch for pressure.

Let us know how you come out after your range session.

Varget gave me it's best results at 44.0 grains with fair accuracy +or-.2 either side. That was with the 150GK. Tried the 165 Accubonds, which shoot well in all of my other 30 caliber rifles.... didn't like them. Also tried 165 grain Hornadys both flat base and boat tail along with the 150 ProHunters. The 150GKs came out on top by a thin edge.

This M70 really prefers 125 Prohunters with W748 but I consider the bullet too lightly constructed for hunting.

MontF,

i well post tomorrow on results with the fresh barreled vanguard. wil be long day as i need to do a break in and go from there.

so what do you figure is max load with Varget for the 150 Gkgs. book shows a much lower charge than i think most folks are using on the 165's at 46grains. i ask as i plan on tying out the OCW method and see how it works for me.

my 270 win loves the 130 Prohunters and Gkgs with either imr 4350 or RE19. one pretty little hole.

Ron

I ran 'em up to 46.0 grains. Accuracy was dropping off with each increase so didn't pursue it futher. At 46.0 there was no pressure signs in my rifle. Hodgdon's specs say 47 pushing a Nosler bullet. Noslers generally require less powder to hit max pressure compaired to many other bullets.

FWIW - I'm loading ~44.5 of H4895 under the 155 grain A-Max and getting excellent accuracy. I like the extreme versatility of H4895, which is excellent for cast bullet rifle loads, as well as reduced-recoil loads.

Getting incredible accuracy from this powder, in my son's 308, has been a welcome bonus.

H4895 is one of two powders I buy in 8 lb jugs. It seems to work for me in a variety of chamberings, many of them quite well.

I haven't tried A-max bullets yet in my .308, might be one of the next i buy.

Powders that I've found to work well in my .308 rifles using 150 grainers are:

1. Varget
2. WW-748
3. IMR-4064
4. IMR-4320

I've never tried H4895 powder but many have with good success.

The "Extreme" properties that Hodgy touts, are cartridge specific. So if you think the difference is statistically valid, use Varget in the 308, NOT 4895.

For 308's I am a longtime lover of W748, now CFE223.
Found pressures with temperature using Varget, not so with the two listed ball powders.

I use 44.5 grains of H4895, CCI 200 LR primers, Winchester cases, and Hornady 150 grain SP Interlock bullets at 2.745" OACL. This load is averaging 2573 fps. in my Ruger scout rifle with 16.5" barrel. This load works well with no problems in MY RIFLE. Start lower and work up as your rifle may have different preferences.

Another load which works well in my rifle is 43.0 grains of IMR 3031, CCI 200 LR primers, Winchester cases, and Hornady 150 grain SP Interlock bullets at 2.475" OACL. It averages 2598 fps. in the scout rifle. It tends to be slightly more accurate than the first load. Start lower and work up. This load was developed in MY RIFLE, and yours may have different tastes.

Good luck and enjoy!

All,


thanks for all the loads and powder suggestions. I have good luck with the H4895, tried IMR 4895 but get more consistent results with the "H", well at the light charges I have been using. same for IMR4064, and RE15. varget is pretty good. think I need to try some charge increments to check pressure and load some from there.

also think I will try the WW748 and 4320 as here and other forums have folks like you suggesting its a very good powder for the 308 win.

any suggestions on a chronograph as to which brand/model. I have an old shooting chrony that is the bottom line (what ever that was) from about 15-18 years ago. I just don't trust its results, when it reads the shot. have been thinking about the Beta Master or the CED M2.

Ron

I have the earlier (M1) CED and an Oehler 35P. Overlapping the screens (Oehler with 4 ft spacing and the CED with 2 ft spacing let's you do that) they always agree within 2 to 8 fps of each other. Bryan Litz mentioned in his book that he found the same thing comparing the two. I've noticed a couple of complaints in the Midway reviews, but they appear to be due to defective parts that would be replaced on warranty. I'd rather have a design I know works well in principle than one I have less faith in, though, so I'd still go with the CED. Whatever you get, see if you can check it against units belonging to others.

Another powder to check out is CFE223. Hornady is showing excellent speeds with that from 150 gr. all the way to 200.

The cadillac of chronographs is the Oehler, but you pay for it. Had one years ago, and like a **** fool I sold it. Now I use a Shooting Chrony F1 Master. The readout is a separate little box that sits on the bench. I have found it to be very accurate, and the price is right at just around $100. The only real difference between it and their more expensive models is the amount of memory.
