And the reason the 6.5 X 55 might be named after a highly skilled WWI German airplane pilot's nick name is. . . . .
You must be very bored today?

around the middle of the article you linked (how is that done?) he says he machined rested the rifles when he did the testing. but the main thing is he is doing that without massive charges of powder in big magnums
I still don't get it lol. I am PC dumbAhh read it thoroughly this time i must have skipped right over it.
To direct link to another site you highlight the address of the site from your address bar when your on that page, then right click if on a computer and choose "copy" or if on a smartphone hold your finger on the address bar for a second or two, and it should automatically give you an option to "copy"
After that from a pc you right click in the post field where you want it to to and hit paste (yeah i just over explained copy and paste......). From a smart phone you need to hold your finger down for a second or two where you want it pasted, then it will give you the menu for that option.
1stmarine, I know you think you're doing something clever, but it's really not. What you've discovered is that some factory ammo is loaded hotter than and some less so. When you compare apples to apples, SAAMI max loads across the board, you will find that all the cases with the same capacity and max pressure will drive projectiles of similar weight to similar speeds out of the same barrel. There is nothing magic about any of the bore sizes.
The .243 will drive a 100 gr to about 3050 ft/s (IMR 7828 SSC)
The 6.5CM will drive a 120 gr to about 3000 ft/s (IMR 4895)
The 7mm-08 will drive a 120 gr to about 3090 ft/s (IMR 4895)
The .308 will drive a 125gr to about 3150 ft/s (H322)
That's all for a 22" barrel. In each case I just ran the load in quick load and took the top IMR/Hodgdon single base powder. With similar technology powders and similar pressure levels, there is no at-the-muzzle performance difference to speak of. The 6mm and 6.5mm will outperform down range due to higher BC depending on exact bullet choice.
Of course the ideal powder gets faster as the bore size increases.
You would see my name and scores ten to twenty places below his when we both shot at the Nationals. He held tighter and doped the wind better than me.would have really liked to witness you and Tubbs shooting together.
What is your source for these numbers?
If they are based on your experience or someone else's protocol, please share the criteria used in their development.
What range? What ammo?M40 barrels can go for 15k rounds within 1/2 moa that is more than acceptable for anyone other than perhaps elite competition
What range? What ammo?
what caliber rifles were you 2 guys shootingYou would see my name and scores ten to twenty places below his when we both shot at the Nationals. He held tighter and doped the wind better than me.
M118 ammo at its best shot almost 2 MOA at 600 yards in precision test barrels, a bit over 1 MOA at 300. M118 ammo lots were made with bullets from 3 or 4 machines; not good for accuracy nor precision shooting.Service M118 right? I am talking about the M40A3 and M40A5. Don't know about earlier models with the hart barrel.
I only shot 30 caliber except my first year at the Nationals for one match when M16's were first allowed, then 22. I shot a 26 caliber magnum for a couple years in local matches Tubb shot 30, 26 and 24 caliber all over as far as I know.what caliber rifles were you 2 guys shooting
