Why left hand twist?

I'm sure there is a great explanation why, but I can't think of it.

I was breaking in my new EABCO Accuracy 6.5X284 barrel yesterday and the jag unscrewed and off my rod. I know it's going to do that, but I thinking about the next shot...shooting my 300wsm in between shots while letting the solvent soak. So I had forgot to tighten the thing.

Sooo, I thought I would find out "Why"?

Oh...how did the new barrel shoot? I was very pleased! I just grabbed a load out of thin air with 140 RDF's...yeah, I know pricey bullet for break in. I ran 5 over the magnetospeed just to see where the load was velocity wise and had a super low SD and ES! So I have a nice starting point once I have a few down the pipe.

I get frowned upon for using budget gear, but I think my entry level "stuff" works just fine!

Savage Axis Action, EABCO Accuracy barrel, Boyds thumb hole stock, Axis trigger kit, EGW base, Vortex rings and Millet MRAD scope.

Any way, let the barrel cool...dialed up my dope from the JBM calculator and fired one shot at clean white steel...400yds.

Used my glasses to give scale on steel size!

I don't know but you got to love a gun that shoots like that. Hope you find it repeatable. Lol I don't want you to shoot at it with my glasses on it.

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

Cost and performance do not share a simple correleation. Absolutely staggering cost is very easily achievable without concomitant performance. It's just easiest to get staggering performance with staggering cost.

The idea that a guy in his garage can't put together a .7MOA-All-Day rifle with parts that tend toward the bargain side is laughable OP. People do it every day. You can thank modern computer controlled machining for all of that. Once you get the craftsman out of the mix you no longer have a "Monday morning car" or a "Friday afternoon car".

Please gawd let everyone in here be old enough to know what the hell a "Friday afternoon car" was.


EDIT: This is not to say that a craftsman is a bad thing, but they've lost their place somewhat in society. Their product has become more niche, oriented at the wealthier and older sets, where it rightly belongs. We'll all be old some day and if we're smart, we'll begin to understand by then what craftsmanship is for.

Shooting seems to be a lot like auto racing. A guy shows up in a beat up pile of junk, yet smokes everyone because he has turned and learned to set up the car. Take a used off the shelf rifle, clean it, bed the action, install pillars and you have a made it as good as you can, with what you have. Of course, you can throw everything but the trigger guard and build back to new or better. I am not a competition shooter. So accuracy mean something different for me. A 3" group of 5 shots or more will fit the bill for me. Now I am not saying I will not work to make it better, just I dont need sub 1/4 moa. I will never knock anyone for what they choose to do or what they shoot. Not everyone, me included, can afford top of the line.

"A 3" group of 5 shots" what distance?

I have one 7RM that with a particular load spec makes a 4-6" group at 100yrds, a 3" group at 500 and a 3" group at 900. I kid you not, group are basically hand size at any distance. I took it to a mile last spring and put down a 10-inch 3 shot group. It's 10-twist and I'm punching 180's out of it so they're not quite as stable as they could be until the bullet has slowed down a bit. Thankfully I have no real reason to really shoot it at anything under 500m.

Well for hunting, for me, any distance. Although I have never had a rifle that didnt shot 2moa or less out of the box. Maybe i just have lower expectations.......that explains my ex ......

Well, there's an excuse to hunt Red Stag in New Zealand with one of my right hand twist rifles!

Also gets me to thinking....if you flush the toilet in a motor home while crossing the equator, will the drain vortex reverse direction?

Glasses don't appear to be damaged. Must be they're ballistic grade lenses

You think you have a LH twist because the Jag unscrewed?

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?

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
