When began this thread, I did not expect such well informed and educational answers! Thanks to all! I shall continue to experiment with the longer jumps!

Most of us have admired the dense, straight, Walnut grain on many US M1 Rifles. It is revealing to report that during the adoption of the US M14 Rifle (1957), the plastic stock was considered and dropped. The reason being that the military believed that the American fighting man wanted only wood...
As a tad, I much admired looking at firearms stocked with fancy wood. Later I discovered that many men who owned those pieces of art that could fire projectiles, never took them out of the gun room! Still, when I began to gather my own battery of hunting pieces, I coveted the fancy wood. In the...
Where was I when the theory changed from getting bullets close to the lands, to seating deeper to give some more jump to the lands?
For years I read that the way to get optimum accuracy, was to seat the bullets very close to the lands and work back until the "sweet" spot was discovered. For...
I have been using the same big Lyman tumbler since the late 1980s. It still functions fine. I don't remember the last time that I changed the corn cob media. I have the restoration liquid that I, on occasion, add to the media. I tumble brass for about 90 minutes. The media is getting more black...
I suppose that if spending 5 minutes a day over the four day period is obsessive, then I am guilty. I have always believed that if the lead and/or copper is not taken out, accuracy will suffer and I like accuracy. I never have worried about barrel replacement, in part, because before I have...
Since killing my first white tail in the early 1960s, I have concerned myself first with making a quick, clean kill with minimal suffering. When I took my doctor on his first hunt, he bagged a mule deer and a pronghorn. Both were heart shots. By time we walked to the animals, they were very...
Elkman, I pray that you and lot more of us here, have many more hunts left to do!
I do remember post WWII days, when my Uncle Arthur returned from the war in Europe and had to wait until 1948 before a Win. M 70 in 220Swift was available anywhere!
Conversions of War Trophies was very common and...
Not being critical, one way or the other, but just being honestly curious. Is there anyone here who only owns one rifle? Barring first season novices, and barring the economic necessities of some, why do you only own and use one rifle? What do you find are the advantages of only owning one...
The older I become and the more that I learn, regarding firearms, the less I seem to understand. I began cleaning rifle bores in the 1950s, when after a day of groundhog shooting in Maryland, I would pull the bolt on my uncles Mod. 70, 220Swift and my Dad's Rem. .222 cal., and runs two or three...
Thanks to "bullet" and others who encouraged me to back off the OAL. For years, I have read that getting close to the lands will reap tighter groups. Maybe I was not reading more recent data?
I really do not think that this rifle likes 120gr. bullets. I tried a number of different OAL...
Perhaps our bent toward certain caliber rifles comes from our beginnings. I was a Cub Scout when my Dad put me in front of a groundhog with my "cat and rat" .22cal. rifle. At 12, I graduated to a .22Hornet and not long after that, to a 220Swift.
Deer were still scarce in the eastern parts of...
Even Jack O'Connor, near the end of his writing days, admitted that the 280Rem nudges out the 270Win. He said that if he had no hunting rifle, he'd buy a rifle in 280Rem, but for someone who already had a 270Win, the 280Rem would not do enough, in terms of an improvement, to warrant the change...
Sorting some cartridge cases around my gun room, I noticed that I have a couple hundred .270 Win. cases. I no longer own a rifle chambered in .270 Win. Seeing those cases made me wonder why I have, over the years, gone from one caliber to the next and one rifle to the next.
My only answer is...
Realizing that each rifle is different, in terms of OAL that turns out to be best, I did get this response from the Sierra Tech Team:

Scotty, is it particular to 7mm-08 that one needs to back off OAL more than usual?
With other calibers that I have loaded for a long time, I am very close to the lands. This like .0005" to .0010" off the lands. With the 7mm-08 I am backing off much farther to try for better groups.

Scotty I will check MV next week.
Bullet, Sierra recommended 2.800" OAL. I will try what you have recommended. I was going by getting the bullet .005" off the lands and working back. It does seem to like getting a jump into the lands.
