Savage 110 ba, 250 gr accubonds, H1000

Anyone have these bullets for the 110? Best group I got was .73x and know that can be MUCH better.

Went from 88.0 to 92 in .5 increments, coal of 3.600.

0.5gr is the kind of increment where one is simply searching for a reasonable group size. Once you find the reasonable group size, you are supposed to perform a sub 0.2% sweep (0.1-0.2 gr in 338LM) to find the sweet spot for this set of brass, that set of bullets, and your particular gun.

After you narrow down the chargeweight, you run bullet depth seating experiments, neck tension experiments, and various case preperation echniques to see just how good you can make your gun shoot.

Sounds to me like you are on step 1.5 of a 5+ step process.

Re: 338 help

I must respectfully disagree about 0.1-0.2 gr. in 338LM. With Retumbo or some other extruded powders 0.5 is more realistic.

Not to mention, the accuracy of the chamber,quality of the barrel etc. H1000 is an excellent powder and probably the LEAST temp sensitive- but frankly 0.5gr. increments are plenty.

Remember, there is a chance,that the barrel you have just won't shoot the accubonds?

At what distance are you attempting to create a load for?

Re: 338 help

This was just at 100 yds...first time I reloaded for this gun.

Will go out to 1200 yds eventually though.



I just finished up loads for my 308 and 243 and was very happy with the results. Not with the 338 though lol.

I don't have lapua brass yet (using my S&B brass from break in) but don't think that's the problem.

I know there's a few people on here with these 110's and trying to find a proven load that I can work up to.

These bullets are short and fat compared to the match bullets I had, and couldn't even load them to mag length without the bullet being jammed into the lands.

Re: 338 help

Its been my experience to stay off the lands,unless its the 300 Berger.After 6K rounds of 338LM, I've gotten the best results with the Hodgdon powders. H1000,Retumbo, US 869, and H50BMG for 30+ inch tubes.

For me load development at 300 yards usually results in good mid range loads to 1000.

Re: 338 help

Anyone have any loads to share? Especially if its a 110ba or 250gr accubond. H1000 powder

I'm going to load some more up this week and give them one more shot before stepping up to 300gr

Re: 338 help

I worked with 250's for a while and got no good results. When I switched to 300's, I got good results right away. I am using 90 gr's of RL-25. I tried other powders, but this was the best one for accuracy/fps. I personally think it's a waste to shoot a 338 at 100 yards.

Re: 338 help

Believe me, I can't wait to stretch the legs on this gun and get to the 1k mark. But if it won't group at 100 yds it won't group at 300 plus. I can do 100 yds in my back yard vs driving 1hr plus to go to a range.

The coal on the last set I loaded up was 3.600 and for the new set I'm loading up this week ill be at 3.680. Maybe and hopefully that will help it some getting it closer to the lands.

Re: 338 help

My 110BA just didn't like 250 grain bullets..even Berger OTM's seated to lands over 92.0 Retumbo and 91.0 H1000. Had to single feed those. Had flyers.

It did like Hornady 285's touching the lands over 90.0 H1000, which still fit in the magazine.

Why not just start at the lands or maybe .01" off the lands as it seems most people have found works best with 300s.

Is that .730" for 5 shots, or 3 shots?

What makes you think that that barrel/rifle/ammo combo will shoot better than <3/4 inch, which isn't too shabby for a Joe Blow factory rifle?

3/4 inch for 5 shots is pretty good and well within that rifle's 'accuracy requirement'.

Re: 338 help

Try some US869 which is a ball powder.

 

[woodland-ghost]

Re: 338 help

.730 for 3 shots, I'm sure it can do much better, I got my 243 and 308 much tighter than that and they're nothing special.

Also that 3.680 coal is pretty close to the lands, 3.690 coal is hard to close the bolt

Maybe the AccuBonds just won't shoot for you? There are plenty of other bullets you can try for hunting applications.

5 shot groups should be the norm, but 3 shots into .73x" is good enough for most hunting applications, I would imagine, but I'm not a hunter, so who knows for sure?

Nosler makes some Ballistic Tips in 225gr IIRC and maybe they will work better in your rifle? Sierra GameKings as well, in 250gr, perhaps? Hornady SSTs?

Take care and good luck.

Re: 338 help

I just wanted 250 gn for the occasional coyote, and that grouping would be more than good enough...after I test these I will be going to a 300 gn match bullet

How much better than sub MOA do you expect from a stock Savage 338? See how it does starting at 300 on out to your goal distance.

Re: 338 help

As others have stated, don't waist time shooting at 100 yards, do your load developments at 300 yards minimum, I think you will be pleasantly surprised with the results. H1000 and RL25 are other great powders to try. 0.50 Grain increments are plenty for ladder test with these powders but once a node is found you can adjust powder charges by 0.10 to fine tune further. Remember that your throat will wear over rounds and your OAL will have to be adjusted to achieve the same "jump".
