    I just found a new savage .338 lapua mag and it is being held for me,so I can drive up and pick it up. I would like to some load info for .300 grn bullet and what velocity I should get. 2. They also have a .338-378 wby accumark and now I can't make up my mind. If anyone has any info on both rifles or input it would be a great help.

    Hi there, i have just brought a Savage 110BA in 338 lapua. i have had it for about one month and fire approx 150 rounds through it doing load development and just practicising/getting used to a new rifle.

    i used to shoot a Sako Varmint in 300winmag and although a very nice gun capable of sub MOA groups......and proven in the feild with a 962 yard one shot kill on a stag.....the round was not as stable as the 338 in the breeze.

    the Savage took approx 70-80 rounds to settle into decent groups.....the first few cleaning sessions showed reasonable copper fouling....but now its great and cleans easily.

    The load i have settled on is as follows:

    300grain Sierra Match King
    Lapua brass
    Federal 215 magnum primers
    88.5 grains of H1000
    loaded overall length of 3.75inches (95.25mm)

    this load produces 2615fps and is very mild to shoot.......i like the load as it is not anywhere near max load but shoots 0.5-0.8MOA tested at 400,800 and 1000 yards. Although i;m not a great shooter and at the 0.8MOA end of the scale out at 1000yards.......i have a freind who is a great shot and he is sub 0.5MOA with this load.

    i'm also hoping that with the relatively light load that i will get a few extra loads out of the expensive lapua brass.

    hope this helps

    If you want to get velocity with the 300 grain bullets I would have to recomend the 338/378
    because of case capacity.

    If velocity is not important the Lapua is an excellent choice.

    With lighter bullets it's a toss up both are capable of good velocities with 250 gr bullets.

    The cost of brass or loaded ammo is high for both .

    I was once the proud owner of a 30-378. At about $3 dollars per case and some of them getting loose primers in just a 2-3 shots. The 28 inch barrels didn't last very long. When it was ready for its third barrel I was going to just change it to the 338-378. But I got an offer for my 200+ cases, all the related reloading, and 700 - 800 hundred of 210 and 240 vld bullets.

    I took the money and toned down from barrel burning and bought a 34 inch 338 Lapua. Very happy:) I decided on 34 inch after reading a test on this forum about a 338 that they started with 42 inch or something and started chopping off one inch at a time and doing the range chrono testing. Very good info.

    I shoot a 338 LM with a 32ā€ barrel and with the 300gr SMK I can get speeds around 2850fps. This gun will shoot sub moa with just about any load, right now I am just trying different powders to see if I can squeeze any more speed out of it!! As far as the brass goes I have been pushing this round since I had it built, and Iā€™m on the seventh reloading of the original 100 pieces and they show no signs of fatigue. I would go with the Lapua over the 338/378 any day of the week. I hope this helps with your decision.
