    Strelock

    Is anyone else out there shooting a 308 with a Bushnell elite drop dot recticle? DOA 600?

    Im wanting to compare notes as according to Strelock my 150 gr SST load of 2206H at 2830 fps is close to the dots ending at the 600 yard drop dots. that my load should be at 593 yards?

    I not so sure with Bushnell recommending even hotter loads for the reticle to work.

    Has anyone had a play???

    What say you?

    a few hundred meters of elevation would give more error than 7 yards at 600, pretty close match i would say.

    Remember that it will also depend on what zoom you are at as to what ranges the holdovers will be.

    Strelok tells me that mine line up almost perfectly for 300, 400, 450, 500yds at 15x zoom. Load is 168gr SMK's at 2700fps.

    It will only give you an idea though until you test them at the various ranges.

    One thing to remember is that in theory 7yds at 600 will give you more error than 7yds at 300, due to the trajectory. The projectile will drop a lot more in that 7yds at 600yds. So if possible play with Strelok, and if it's a choice between a small error at the closer holdovers or at the longer holdovers, go for the closer ones. Then go test them at the different ranges.

    Ill have to get on a longer range shoot to see what the story is, I using 44.4 grains of 2206H, can go up to 45.6 max. i should see what velocity this gives.

    Mines a 3-9x40 so the dots are calulated on 9 power.

    Help an idiot out...?

    Gone to using factory hornady American whitetail 308 150gr (what I had lying round, someone else using rifle) sighted in with new scope and stock last night at 100m, 1.5inch groupings... It will do, could have done better on my part. Went out to 350 yards and drop was around 9.5-10.

    This morning playing wih Strelock I can't get it to behave, box says muzzle velocity 2820fps and a bc of. 338 (online) Strelock puts his at 5.75MOA for 350... Help?!

    350m is about the limit of my shooting ability anyway but just be nice to work it all out.

    Rifles a t3 with full length barrel and a Dpt on the end running a Vx1 4-12*40

    In my very limited experience, factory stated MV are often optimistic at best.
    Borrow a chrony and get the numbers from that

    No can do before my trip... Velocity has to come up to 3200fps for it to be right... Doubt it somehow. Real world tells me it's a bit over an extended hand span thumb to little finger so gives me a good ballpark hold over as I can't be bothered twiddling knobs with this scope

    Sounds like a pretty typical factory 150 grn .308 load.

    Just bump the velocity back to where it fits?

    I just got strelok+ myself and so far find it rather fiddly compared to shooter.
    Will be sticking with shooter as it has not let me down yet.

    That BC sounds low, even for a 150 gr 308, but thats what the website says. Also check the figures for scope height and POI above aiming point at 100m. Probably around a 2.8-3" vertical offset? That speed does sound fast off the packet. What barrel length you shooting from?

    I just ran your numbers through strelok+ myself and it seems 300m is about the point that pill will drop off in its arc. Ran it at 2700fps and moa was around 4.7 at 350. I guess it is that shitty BC!

    Box reckons:
    100yd = +1.9
    200yd =0
    300ydyd = -8.4
    400yd = starts to fall24.9
    500 falls off the earth at -51

    I just re ran my hand load set up with 150gr SST pushed at 2690fps. BC is .415 I think, ie still shitty. You can see the ballistics aren't too dissimilar to that previous table with your numbers but mine is carrying a little more energy further. Basically at 350 my load is only an inch above yours so suffering the same peril of being a 150 gr 308.

    Cheers @Feral has added to my knowledge but using 100yd zero.

    Need to measure scope height again. By the time I have it sorted I'll be swapping scopes for the set up to the Toby shoot. Maybe I need 2 308s....

    Or just different 308 loads
