What is the sQuare rewt of sod ?

I opened the chokes in a pair of Lefever'Optimus'12b bbls. Orig. choke Dim were both L/R 041" Opened the L to .005" rt to .009". I kept a magnet under paper when cleaning off the 'Swarf'.The total weight I collected with the cutting oil, was 3/4 of oz.This was not a 'Real precision measurement'I used my 'Postal scale'I have a photo of the 3/4oz in a plastic container in the W/shop. cc/dt

I did a swag at the metal volume removed and it doesn't look like it could be more than 0.3 oz total. But that was generous on metal removal. So, my real guess is 3lbs 15.4 oz.

Miller and Chuck are right on, in fact, Chuck is exactly right. The barrels weighed back in at 3 lbs. 15.4 oz. Good cypherin' guys.

So, will I have a lot of problem with gettin' too far in front of a slow crosser, now? Maybe Jonty can help me figure if a left or a right crosser will take less muzzle speed due to continental drift.

It took me several years to decide to open those chokes, and I may not have done it if the gun had still been original, but since it had been re-everythinged already............. It'll be much more useful now. The big HE will remain as is as long as it's mine, .042 and .043.

Due to the extra speed of the swing, if the swing were in a north/south direction, the extra gyroscopic effect of the earth's rotation could cause you to either fall forward or backward, depending on which way you were facing.

This post makes me want to hang up my guns.
The thought of being associated with such lunacy
really bothers me. I'm serious.

Would the speed of swing be faster North or South of the Equator ?

It would be the same if you were the same distance from the equator north or south, but in a different direction. The biggest adjustment would have to be made, naturally, if one were ON the equator.

You guys are gunna be REALLY disappointed......not one mention of the Solunar Tables...if ya messed with those chokes in a minor period and fired 'em in a major.....it might shoot BACKWARDS!!!...or meybe just twice as fast, "Midnight Magnum" ?

Good fer witches and bats?

Stan,
Could you please furnish me with the original dimensions please? Also I would require the current dimensions to promolgate the actual amount of metal removed, also it would be useful if you knew what the actual barrel material is because this obviously affects the specific density and metallurgical make up.No problem if this is not to hand as I am not too far from Sheffield which used to be the steel industry capital and no doubt I can find the information from their reference library.If that draws a blank I have a friend who was a representative for Bohler steels in Austria before they went tits up due to the burgeoning Chinese economy, which incidentally is funded by Brits & Yanks who have moved their businesses out there due to Union interference and the ever shortening working week, which in Germany as become a major problem as they seem to have a religious festival which takes place nearly every week on a Friday which means that the workforce is usually intoxicated all weekend running into the following week with sickness before running into the following weeks festival, which may not be as bad as France who have a complete shut down in August.If you could let me have those dimensions I would appreciate it.Failing that if you post me your address I could come over and stay with you for a month and we could do the calculations hands on, which would probably be a better idea anyway. So I will just go and pack a flight bag and await your reply. I don't have a problem with a visa because when I went to the American Embassy and spoke to the lady their she transferred me to another man in fact I was transferred a lot but they gave me a visa very quickly and waved me goodbye . I will see you later, I'll ring from the airport when I touch down. Don't worry if it takes a long time to come and collect me, I'll find someone to talk to.Bye.
