My Win 70 in 7RM likes it jammed about .002 but after pulling a slug, I only do .001 jump. But that is still too long for the mag. However, 1 round in the chamber and 1 round on top of the mag works fine. And the bolt will cycle that round on top perfectly. So that gives me a 2 shot rifle. Then I put 2 short ones in the mag first and that gives me a good 3rd followup shot if necessary; so far, knock on wood, I've not used even the 2nd shot.Although some rifles like the bullet touching or jammed in the land, there is always the chance that the bullet will pull out, when extracting a loaded round. You must have very consistent seating depth to prevent dumping your powder into the action. This is why you hardly see the bullet jammed in hunting rifles.
I assume he means 2 x1000ths, ie 0.002"This is a local matter, and not a matter of opinion, but of tested best.
Do you mean 2" or .002", or something else?
I was just asking for confirmation. It's possible to matter.I assume he means 2 x1000ths, ie 0.002"
I just purchased a Nosler Long Range Carbon Rifle, chambered in 28 Nosler, and have started working on a load using the 175 ELDX bullet. I tried Norma 217 powder but was unable to find a consistent charge weight. The velocities were all over the place. I tried Retumbo and have a good velocity node around 81 grains and velocity just over 3200 fps.
Having read the discussion above, I can see it may take many rounds to find the right jump. Does anyone have experience with this bullet, powder, and cartridge combination that may be helpful in minimizing the number of rounds down the barrel and still find an accurate load.
Skip,There seems to be a question of varying opinion on whether to have a 2000 th jump to the lands and option of bullet touching the lands for best accuracy. What's everyone's thoughts here?
