500 Yard Standing Offhand CHALLENGE

[fish_e_o]

i was impressed by the 300 yard one by Bergerboy i'm astounded by the 500 yard target

nice work

[Bergerboy]

What is even more amazing is if you use an extremely long 200 yard zero for a 38-55, the standard 255gr flat nosed bullet and a ripping 1600ft/second, the shooter would have to be aiming roughly 185" or 15.5 feet above the target. It would also be interesting to see if any of that target is left unobscured by the front blade of the sight.

A 500 yard zero was used. Front globe sight as well, so no blade...

The rifle is a Model 94 in 38-55, with a bit of work done to it...

Unbelievable! Just WOW.

I tried with a Finnlight 270wsm, Zeiss scope. I gave up after ten shots for zero.

A 38-55 hitting at 500 yards? Geeze, trying to shame everyone into trying? Lol. excellent shooting

[Lefty-Canuck]

Nice shooting!

The more I look into this 38-55 tack driver the more amazed I get! This bullet goes transonic at 265 yards! I cannot believe that maintain stabilized flight for the remaining 245 yards and none have keyholed through the target!

You are making a few assumptions that aren't correct. 255 grain projectiles were used, but faster than 1600.
It is an old rifle, and I have had it for a long time. It was of the first rilfes I ever purchased, from an old timer in BC. When I bought it, all of the small parts were in a coffee can, and the barrel and mag tube were in bad shape. Bore was good though. I have shot this rilfe lots, and at greater distances. The only time I have had a bullet go sideways was trying some "experimental" slugs that turned out to be .375"...

I am actually a fan of the 38-55, what bullet at what velocity were you using?

[sns2]

This is likely the most impressive display of "hunting shooting" I have seen. Just awesome. I bet your freezer is full. Great job!

Thank you for the compliment, but this was no means a hunting type situation.

But yes, my freezer is full.

Rman, that is some pretty skookum offhand shooting. I notice some kind of "sight" on your gun. How does that setup work. I punched in your calibre, bullet weight and speed and it drew me this trajectory (I could not find the barnes bullet but this should be close)










Are you still able to see the target with that sight? I am assuming one would have to aim pretty high to compensate for the bullet drop.

I have a .450 marlin and i am keen to see how far i can lob a bullet with her

By the looks of that graph, his 38-55 would have been at quite an angle!

[marxman]

Rman why dont you play it straight like anyone else would do and shoot the challenge with something normal this stunt is like chinese to me i have no idea what it means

The line of sight remains flat, regardless of the angle on the rifle...
And again, lots have shot this round further, and more accurately, well beyond this distance.

The line of sight does remain flat. The inclination of the barrel does not.

So what is the inclination needed?

You do realize that is inches on the Y axis? How angled is a rifle holding 45" above line of sight at ~300 yards?

Yes I do.

As long as you have enough elevation on the rear sight, an adjustable aperture, and a front sight insert of the appropriate diameter, some patience, and the ability to process the information provided by actually shooting at targets, you should be pleasantly surprised at how far you can hit the right sized circle.

Yeah surprised is right.

You seem to have questions you need to ask. Why don't you just ask them?

I could ask questions. I really like honest answers. Cant see that happening.

Yeah, every time I hit the gong at 500 yards I am pleasantly surprised.

[Pudelpointer]

Wow, there is so much "win" on this thread it is shocking.


First, a quick search shows commercially available ammo available for the 38-55 running a 255 @ 2950.... so it is not at all a stretch to run a 255 at 2100 - is it "over pressure" for the cartridge design? Yes, it very likely is. Is it over pressure for the rifle in question, possibly but obviously not catastrophically.


FYI you cannot "convert" CUP to PSI. You can make an educated guess, but that's it.

As for the continued assertion that a 255gr ~.377 bullet will become "unstable" as it changes state from supersonic to subsonic show a lack of understanding of ballistics. Will a long nosed, ultra high BC Berger become a tumbling hunk of metal changing states? Absolutely. Will a heavy, stout, sub 2.5 BC lose its stability making the same transition? Maybe some should get that figured out before commenting further.


Do the "naysayers" have personal experience with Rman that would cause them to disbelieve his marksmanship? Or are you just unable to accept it?

I don't know Rman, but I have no reason to doubt his claim. Now, if he later admitted that he was actually leaning on the hood of his truck....

[Pudelpointer]

Since others can't figure it out.... the 375 Win (available in the '94) runs at 50,000CUP.



Just, wow.

not... yet. metal fatigue is a funny thing. although he may shoot it many years and be fine it does not mean that there is no potential for damage.

i would be very angry if a friend handed me a rifle and i shot it only later to be told he was deliberately loading over the limit.

different strokes for different folks.

Nice shooting Rman. You clearly put your work in and got results.
