Why left hand twist?

[lancetkenyon]

If you shoot in the Northern Hemisphere the left hand twist will offset the drift to the right due to Coriolis somewhat.

I have heard this before. But you are talking a few inches at 1000 yards difference.

I have a .30-06 Winchester Enfield w. 1:10" left hand twist. The difference in spin drift, besides direction of drift, is only 2"-3", depending on azimuth. Basically, 1mph of wind will push a bullet more than the effects of a left hand twist vs right hand twist. And since I don't have an indoor 1000 yard range, I can't do any actual testing for verification.

That being said, 97% of rifles use a right hand twist.

But it is cool to have a left hand twist WWII era enfield.

Skipglo, I feel the same way. I dont need to or probably can hit anything at a mile no matter what I use. I havent had a deer complain about my ---- being off by a fee inches yet. For the cost of some of these scopes I can build several erifles.....and not just with cheap junk. The one I plan on building now should cost around $2000 glass and all. I am all about less is more......except for beer or whiskey

Lmao.... Amen to that

Wow....honesty! And no regrets. I was much more into accuracy 46 years ago my friend. I was happy with 2.75 inches at any distance. The difference is we were shooting for meat and 2.75 or 3" got the job done. Way too much television and you tube today
Hell every 6 year old today is shooting 1/4 moa at 3 miles..... aren't they? Ballistic cell phone programs, wind meters and laser rangefinders, and 1 mile spotting scopes...sorry 10 mile spotting scopes, and range dial shoot scopes...yes life is better with them, no doubt...but I wonder.,.how many 4 inch at 800 yrd groups there are today....with open sights...you know...the ones that came with the gun?

My good friend from Princeton, MN has a son 22 or 23 whom is a National Small Bore Champion. Eric Hazelton is his name. This young man hits the 10X ring on a target at 1,000 yards, Standing with NO MECHANICAL REST! Just a Leather jacket, OPEN STEEL APEATURE SIGHTS with an 80gr. SIERRA HPBT MATCH KING outta a .223. Feel WELCOME to CONFIRM THIS I FORMATION on CAMP PERRY'S website. Or simply GOOGLE Eric Hazelton! Now that's SHOOTING FELLAS!

Here's me doing an offhand shot at 800yrds with a 7BR running 154gr pills at 2250fps. They go transonic right about at 800 or I'd have shot at the 900yrds target.

Anyway, you'll see the target swing when it gets hit. To find the target follow the road up to near where it ends. Where it makes a loop at the end you'll see 2 horizontal target lines. Those are the silhouette targets. The 800 yrd target is on the right side of the road roughly between those 2 horizontal lines, more toward the lower horizontal than the upper. Watch for movement when the shot goes off and you'll see it.

Short version. Crank the sound AFTER THE SHOT to hear the hit.

Nice Shootin sir! I raised a few EYE BROWS with this HOG taken at 873 yards 1 1/2 years ago with my .308 Sendero, 168 HPBT Match Handloads. The 4 WITNESSES were Strokin me as I was Dopin my scope about SUBSONIC, TRANSONIC! BUT I think it was BIONIC they called me when they saw the HOG do a 3ft Backflip! He he he

PS: The HOG had NOTHING to SAY! GO FIGURE...

Please tell me you were standing up. Wouldn't matter if you weren't but somehow it would if you were because that's a 3" wide target a solid half mile away. By any standard, well done.

873yds is impressive no mater what position you shot from!

Hogs move around so much, you were fortunate the bullet arrived before he moved!

Congrats on a hell of a shot!

theosmithjr...I'm on a cruise in the Caribbean and we are in St. Thomas USVI and I just got strong enough data to see your pictures.

Daym your talking Ground Hogs! I thought we were talking wild pigs!

Great shooting...I have not taken a shot at a GH since the late 70's.
