.308 Accuracy Loads w/165gr

Just curious of what your accuracy loads are for .308 rifles using 165 gr bullet

Pictures of groups would be cool also

IMR 4064 and Varget seem to work really well with 4064 performing just a little better for me.

no real way to answer that, its gonna vary rifle to rifle. Need more information like what your shooting it out of, what kind of bullets your using and so on...

I was just trying to get other people's load performance just out of curiosity but I am shooting Hornady 165gr SST/Interlock out of a Savage 10FXP 1:10" twist and believe it is a 22" barrel

I havent been to the range in a while so no targets that I can find, but I shoot 165gr SST's. CCI large rifle primers, remington brass, 43.8gr of varget will give me sub moa every time, and the occasional 1/2" group... this is just rested on my shooting gear bag, no vice or anything cool like that....

42.5gr of military pulldown 4895, using a CCI LR primer and Federal, Remington, or Winchester brass usually produces a good load in my rifle. I originally tested this load for 168gr Speer BTHPs, but found that it also worked very well for other bullets. This charge weight has a wide sweet spot in my rifle.

I highly recommend using Dan Newberry's Optimal Charge Weight method to develop your own load.

I just loaded Interlock BTSP 165gr using that method. Had some issues with my Lee Scale and my digital Frankford Arsenal scale batteries ran low so was inconsistant so had to get new batteries. Could not get LEE scale to stay zero or give accurate readings.

The trick to the lee scale is to put the beam on the base the exact same way every time. I will take it and put it on, then move it all the way to one side, and then back untill its in the right spot... its harder to explain then to do... Look closly at the underside of the beam and the slot where it fits in the base, Its basicaly a blade the fits down into a slot, and if you're not careful on how you do it, you can get it in different each time, and get inconsistent readings. Once you figure it out, its very accurate, I trust it more than my digital frankford arsenal scale, which I got just as a backup to verify the lee scale. I thought it as off since it showed the powder drops from my auto disk as much lower than the chart said they were, but of course I have since learned that the drops from the auto disk are ALWAYS lower than the chart says they are

dacaur:do you take the beam off to set the weight you are trying to get out of the load or leave it on the base while adjusting it? I will take it off and look for the slot like you were talking about and maybe this will help me use it. When it was on the other week, my FA digital scale was exactly on according to the Lee Scale. Do you find your FA to be accurate?

Yea I take the beam off the base to adjust. Any time my lee beam scale acts wonky I know the end is probably touching the magnet. just reposition so its not touching and its good again. On mine, the end is really close to the "front" magnet so if its not on just right it touches, but I can get it on good the first try 9 times out of 10...

I'm not sure about the FA scale yet... If I calibrate it it works and matches the lee scale, but a few times its started to go off track, and I have had to calibrate it again, but its like 45F in my basement where I am loading so i wonder if the cold is affecting it or something...

I dont entirely trust it yet, I still like to verify things with my beam scale before loading, but I use it to adjust my perfect powder measure for load development and switching between calibers, makes it much easier to know how far off I am on the load I am trying to drop.... I've only used it a few times though....

dacaur: when you say adjust it to not hit magnet how do you do this? or is that fixed when you put it on straight where it balances on that small slit on the base? I went out and saw what you were talking about and checked and seemed to be working better.... FA says 50 degrees up to 90 I believe in the instructions maybe that may be making it off sometimes

yea, just reposition it so the end isnt touching the magnet. it seems it can go into the slit slightly crookid, and when it does it skims the magnet slightly and messes things up, I just wiggle it a little in the base so its not touching anymore...

goin out tom to try new loads using RL 15 and new bullets(Interlock BTSP vs SSTs). Suppose to be windy so will see how it goes though. Used OCW load development

Are the weights written on the target all you are using? If so, they are way too far apart, IMO. When I developed my .308 load for hunting, I loaded 5 rounds each in .2gr increments. If I did it again I would do 3 round groups rather than 5, and I would start about midway in the powder range rather than at the min load, I went through a lot of bullets, and found a LOT of loads didn't work well. Its amazing how just little bits of powder can make such a big difference. Some weights gave groups as much as 2.5 inches! The difference between 43.6 and 43.8 was dramatic for being only .2grains.... 43.6 gave about 1.5" groups, and 43.8 gives sub moa every time. You could just be passing right over the sweet spot.....

Right now I am developing a load for my uncles .300 savage with a different method, where you load 1 round each in .5gr increments from min to max and shoot them all at one target, starting from low to high they will track up the target as the powder increases, and at some point several rounds will all be in the same vertical axis, and thats where you start load development. We did that part a couple weeks ago, and based on that I am loading 3 rounds each of 38.8, 39, 39.2, 39.4 and 39.6gr, and hopefully one of those will be the cats meow in his dad's old gun....

yes. well I did this way based on numerous suggestions on Dan Newberry's load development http://optimalchargeweight.embarqspace.com/? I am new to this so tried a new method for this batch. Any suggestions on better way would be nice. out of those groups I believe 42.9 shot the best


So the method you just mentioned at some point the different loads will start hitting the same spot vertically at the target and then you use those loads to work up? I planned on loading 42.7,42.8,42.9,43.0,43.1,and 43.2 tom to see

Browning... Varget, RL15, and 4064 all have almost identical burn rates.

Try some IMR4064 or something with a similar burn rate.

And ya gotta be certain that copper is being kept at a resonable level and that you are using good shooting techniques.

QL is predicting IMR4064 should be a great powder for this combo.
Nice velocity and a slightly compressed load to take powder position out of the equation.

RL15 is showing 44,468psi, 2585fps and 92.2% case fill at 42.9gr.

IDK what your book max is on the RL15, but it looks like it could go much higher.

QL says even at 47gr you are still within safe pressure limits.

So, up that charge of RL15, and if that don't work, get some IMR4064

Can I ask why you are staying so low on the powder charge?

just started working up on RL-15 and new to reloading so started about 10%below max. books are stating 44.3-44.5 is MAX fot this bullet.

In Newberry's method, you charges should be no more than .2-.3 grains apart. Your loads on that photo were much farther apart, which defeats the purpose.
Use a narrower range of powder weights, and shoot with .3gr apart. Round robin the groups, shooting 1 of 1 charge weight, then 1 of the next charge weight, and then back to the starting charge weight.
You're looking for where there's a large sweet spot, not necessarily for the best group. 42.9 is the best group, but it would make for a bad load if 42.8gr and 43gr loads go to completely different locations. You want a spot where at least 3 charge weights worth of groups shoot very close to the same POI. Then load the middle charge. That should give you the most "stable" powder charge.

well his method states start 7-10% below max(which in manuals is 44.5gr). And I understand not looking for best group but consistant POI. So starting below that states load 1 bullet@2% above that, then another @2%, then another at 2% to have sighters and check for pressure. Then for the loads of 3 bullets it states go (.7-1% above then keep going up in those increments from previous load).

So that should look like this if my math is correct(using 1%increase in load):
1@40.5,41.3,42,1
3@42.5,42.9,43.3,43.7,44.1,44.5,44.9


using .7%:
1@40.5,41.3,42,1
2@42.4,42.7,42.9,43.2,43.5,43.8,44.1,44.4,44.7


at 1% looks like increase of .4gr and at .7% it is .3gr increase


So would I do the .7% or just go up .2gr each load and work up?

Hmmm.... I checked that dan newberry link for the first time.... seems like a lot of BS to me.... it talks about creating a universal "starting" load that will shoot well in all rifles... well, if thats the case, then why not just develop the load once and tell us the recipe? If we each need to follow the description and develop the "OCW" load on our own, then that would suggest that "all rifles are different" after all, which it seems he is trying to disprove in the first place....... Just My $0.02.

It also seems strikingly similar to the method I described above where you load a bunch in .5 grain increments, shoot them all at a single target, and look for the 1.5-2 grain range where they all group at about the same vertical axis, which would be the OCW range, according the the link, then you fine tune from there.... seems like his method does the same thing, just with a lot more bullets wasted finding that optimal range....

dacaur: I think I responded to your method but can't remember. You just shoot one round and look for same POI then how do you fine tune from there?
