338 Lapua 250 vs 300 in 1x9 twist Savage?

I just got a 338 lapua in the savage 110ba and need help on reloading. Whats a good accurate bullet for this gun...it has a 1x9 twist i think. I see alot of people shoot the 300's instead of the 250. why is that....i was hoping the 250 will work since it would be flatter shooting, and slightly less kick. Please give any recommendations on bullets and powder...thanks

The 250 grain bullets are my choice because at the distance the Lapua is capable of the 250
grain will have flatter trajectory and just as much energy because of velocity.

If I were going to shoot 300 grain bullets I would opt for a larger case (338/378, 338 Excalibur
ETC. to get the velocity at or above 3000 ft/sec.

Any good 250 grain bullet will give you every thing you want. I use the 250 grain Accubond
because of its performance at POI. Sometimes depending on the game and distance I use
the 225 Accubond and It is amazing.

My 338s are all 1 in 10 twist so you should do fine with the 1 in 9.

Re: 338 Lapua 250 vs 300 in 1x9 twist Savage?

good friend here is loading for the Savage. He found with the 1 in 9 that the 300's did much better. His groups were tighter by far. His thoughts were that the 9 twist was almost to fast for the 250's.

Not saying he is right or wrong on that thought, but all his testing he did, the 300's shined over the 250's.

Re: 338 Lapua 250 vs 300 in 1x9 twist Savage?

i have the 110Ba in 338LM....

my load is:
300g SMK
Lapua brass
88.5g H1000
fed 215M primers
3.75 over all length

just fits the magazine and shoots 0.5-0.6 MOA out to 1000 yards

my rifle to 70-80 rounds to settle but i now have 150 rounds through it and it just keeps getting better and better.

Re: 338 Lapua 250 vs 300 in 1x9 twist Savage?

here are the two proven loads for my BA110
both shoot sub moa (probably around 1/2 moa and better if i am on my game)

225gr nosler accubond
neck sized lapua brass
CCI LR magnum primers
87.0gr IMR 7828ssc
OAL 3.670"
2900fps muzzle and stays supersonic till about 1300 yards depending on atmospherics

300gr SMK
89.2gr Retumbo
cci lr magnum primer
lapua neck sized brass
OAL 3.714"
2780 fps muzzle and stays supersonic till about 1900 yards


haven't been doing too much with 250grainers (have only shot over a chrono with hornady factory loads)
the 300's have been shooting well and the 225gr accubonds were one of the fist loads i made for it and they have been shooting so good i haven't felt the need to waste powder on load developement for the 250's at this point .....

on a side note from what i have found regarding the 1 in 9 twist rate... i have heard people say "the 1-9 is too fast for the 250's and lighter etc.... " but my 225gr load seems to shoot great, seemingly in contradiction to the "too fast" claim

as for the 250's being flatter shooting....
according to my ballistic program the trajectory to 1000 is a wash when shooting 250's at 2920fps and 300's at 2780fps,
the 250's are 5.8MOA for 10mph wind @1000 vrs 5.4MOA for the 300's,again a wash
the 250"s have 1718 ftlbs @ 1000 vrs 2078 ftlbs for the 300's
250's go transsonic around 1700 vrs around 1900 for the 300's....
so i would say try both and pick the most accurate one because unless you are pushing it out further than a mile you wont be disapointed by either...

I have to agree with J E custom that the 250's will probably give you everything you want... the 300's might just give you a bit more ...

as for the recoil the brake on the 110BA makes my 300grain loads kick like my 308....
