    Just for question, What kinda accuracy are you guy's getting with the accumarks factory? Mostly the 338-378, 30-378 and the 257 weatherby if they make it. Thanks

    I am getting 1" groups @ 100 Yards and suspect that a better shooter with better bench equipment could get much better out of her. I'm not even using premium ammo, just some Remington core-loc garbage off the shelves at Wal-Mart. I used to have the 30-378 and thought it was rediculous for what I needed. It was a testosterone purchase shortly after the rifle/caliber combo came out. I now have one in 300 Win. Mag and am very pleased with it. I'd like to think after a little smithing and some premium handloads, it would be 1/2" or better. Hell, it might be now............. I'm not the best shooter. /ubbthreads/images/graemlins/frown.gif

    Depends on the loads.
    The 338-378 is the newest but so far it has already shot a bunch of 1" groups with just throwing it together. No load development. We are still breaking in the barrel. The current load is out of the Barnes book. 108 grains of RL-22 shoots 225 TSX's at 3202fps but the ES is running about 50 fps. It will need some work but still 450 yard testing it is very impressive. I want to try some 225 Accubonds and some other powders in it next. 3300fps should be doable. I don't have a 30-378 but do have a 300wby and 2-257's. My 14 year old wouldn't give mine back till he got his own. The 257's shoot light bullets best so far. I have BD 8-32 on mine and use it for varminting. The 300Wby is shooting 200 grain Accubonds into .6 inch groups at the moment. I'm still working with it. I bought it used but the guy I bought it from said it shot 4” groups at 500 yards for him with TSX’s. The triggers on all of these are adjusted to around 1 to 1-1/2 pounds. Depends on who is going to be shooting it. My 257 is set at 15 ounces. They all are very sweet rifles. I never used to think much of muzzle brakes but now I wish they all had them. They all are really fun to shoot. We have been doing a lot of 450 yard shooting on water bottles. Next weekend we go out we are moving the targets out to 700 to make it more challenging.

    So 1-1.5moa at 100yrds isnt to bad with this rifle /ubbthreads/images/graemlins/confused.gif It has a nxs with night force mounting hardware. It's the 338-378. Any body have any loads I should try? Thanks

    I would expect it to shoot under 1". What are you looking to shoot with it. What game animals, how far? I'm thinking it is capable of anything on this planet. If you just punching paper or varminting with it you can use non-premium bullets. The Barnes book seems to have the most up to date load info for the 338-378. The info lines up on my Pact chonograph very close. They are pleasing to look at too, don't you think.

    Mostly deer and elk. Up to 600yrds if I can find a good shooting load.

    That will be easy. Now, how do you like your loads? Fast and flat as in 3500+ fps or slow and steady? We are working on the middle ground with the 225 grain bullets at the moment. When we get something that is really tight I will sound off.

    Those are the most hideous looking guns I have ever seen who did you say makes them?? They probably don’t shot any better than they look. Just kidding I love my AccuMarks

    Mostly looking for a good accurate load. It will mostly be used for deer so the fast and flat would probably be best. If you have any experience with good shooting loads out of the accumark I would like to know. I know mine wont shoot the same but would still like some suggestions. Thanks

    Screech,
    I just have to ask, did a deer do something bad to you when you were young? Why the cannon for just a deer?

    Just for fun. I've shot them with lots of calibers from .243 to 300rum in the past. I shot one last year with it but I'm hoping for some better accuracy. Thanks

    I know what you mean about shooting the big gun for fun. My cousin shoots deer with a 375 Wby.

    Here is 3 shots rapid fire from my Accumark in 257Wby. Don't forget to subtract .257 from the reading on the caliper to see the real group size. Sorry the pic is so big.
