So you think you need high BC and magnificantion for long range shooting....

    Well, Its common knowledge that you need a BC of at least .5 and preferably +.7 to have real long range consistency. Also common knowledge that if you do not have a high powered scope, your just wasting your time, at least that's what some think. Personally, I feel image quality is far more important then mag power.

    Anyway, just tested a rifle that SHOULD NOT be a long range chambering at least in the load used for this testing so wanted to offer some video proof that sometimes a non long range bullet can really surprise us and with a low powered scope.

    The rifle specs are as follows:

    APS Raptor Stalker rifle (10 lb bare rifle weight)
    375 Allen Xpress
    26" barrel length
    Swaro 1-6x scope (non parallax adjustable)
    350 gr TSX loaded to 2800 fps (.420 BC)

    Now, this load is for hammering a cape buff at 50 yards.....

    Here are some pics of the rifle

    Anyway, here is a clip of the long range accuracy test session with this rifle and 350 gr TSX at a measured 1070 yards. First shot was taken after testing with the 250 gr TTSX so that's the reason for the low impact. After a scope adjustment the rifle was landing within 1/2 moa of point of aim which was the white spot running diagonal in the center of the view. Turned out this was an old cow pie which is why the second shot after the scope adjustment is very difficult to see. If you look close you will see it impact on the far left edge of the target with not much signature. The rest landed just below the target.

    Now, remember this rifle is fitted with a 1-6x scope that has no parallax adjustment. The target is roughly 1 moa wide and 1/2 moa tall to give reference to the group size. For more reference, the small round white rock down and to the left of the impact sight is 1/4 moa in size. Most of the shots fired went WELL under 1/2 moa with all easily going under 3/4 moa.

    Wind conditions were also a bit tricky, at my shooting position, the wind was full value 8-10 mph from my right. At the shooting location, it was around 10 mph but from the 2 o'clock direction. Made very little difference.

    Anyway, think this rifle and load could EASILY hammer a whitetail at 1070 yards!!!

    Nothing like having a rifle that could not be better suited for taking a cape buff at 25 yards or chasing brown bears in Alaska and on the same day take a Kudu or caribou at +1000 yards with just a scope dial up!!!! They do not get much more flexible then this.

    Another very interesting post about what is possible with equipment that most folks don't think of as long range!

    I have been doing some work along the same lines to see what is possible with my 375 H&H. My initial results exceeded my expectations. I still need to finish load development and get some shooting done @ 600 yards to validate my numbers. I don't have access to a longer range than that, so 600 it is.

    I fooled around some with 250g TTSX's, but had such good results with 300g bullets that I have decided to go that direction. I started out with a Meopta 1.5-6x42. It's a great scope for field use and offhand shooting, but the eye relief is a bit short for bench work.

    It looks to me like Hornady 300g BTSP's @ 2700ish will work very well with a RZ 1000 reticle and carry enough freight to take a deer at 1000 yards. I just happen to have a scope with that reticle and plan to test the combination.

    If I can get them to shoot, CE 300's or 320's will take me out to around 1500. Then I will have to find some place where I can shoot that far!

    Thanks again for some excellent information. I really like the .375's and feel there is a lot of untapped potential to be had there. I find it encouraging to see the results of your work! gun)

    I am getting the same thing. I will take fiftydriver's word for it. Would love to see the video, though.

    Me too. I don't have a pass word or account. That is a nasty looking hammer though. Those Buff should be loosing sleep.

    All I see is a hillside and a rock of an unknown size and bullet rounds hitting somewhere in the vicinity of the rock. There is nothing measurable here so I have no idea if you have a 1 moa group or a 5 moa group.

    Set up a target and give us some actual measurements. IMO this video means nothing other than your rounds are hitting in the same general area, which any rifle could do.

    Well the video was very clear to me. The shots looked well under MOA from the video and if Kirby said it was half MOA or less than that's what it was.

    Beautiful rifle Kirby, and great shooting! What twist is the bore and what's the magazine length?

    Got it. Cool video. I won't quibble over the finer points,but I will say this. I don't want him shooting at me at 1,070! gun) 6X scope or not.

    Yes I agree . This proves or highlights nothing in my view.
    Although I do agree that high quality glass is better than lower quality but higher power in most cases and to a point .
    Eye sight has a lot to do with it also , with 20 20 vision and a top quality scope you can see better than some other people who have less than perfect vision and no so high quality scopes.
    I think the needs of personal choice is a whole lot more complicated than what one single person may be happy with.
    I know a young guy that can see my 30 cal holes in the target at 200 meters with the naked eye.
    I can't see them at 50 meters . There is no way we are going to be happy with the same scope power .

    I think you missed the whole point,:rolleyes: nice shooting Kirby I wish I had a place for one of your rifles. Living in the Midwest really big hammers are some what impractical.:D
