Bullet Jump Help

[shootingcharley 3]

Just wondering if anyone has had this problem and how did they solve it? I have a Ruger Target Varmint in .204 it appears that it has a built in bullet jump? as when i put the OAL gage in and push the bullet in to get a setting the bullet just falls out of the end of the case it will not reach the lands ??, Has anyone had this and how did they get round it.

There is no way around it. Most of the time you will tighten your groups by seating just off the lands but that is not always the case!

You can tighten your groups by neck turning and seating your bullets with no run out and more often than not, this will produce more accurate ammunition than seating just off the lands alone.

I certainly would not despair, fact is your shooting a hunting rifle with a hunting load, correct? If so, then squeezing every last BR micro millimeter isn't necessary.

With a bullet falling out of the case before the ogive touches the lands when using an AOL gauge, the way around it is to hold the fifle pointing upwards vertically push slider until bullet touches lands - lock off, then measure the bullet from base to ogive then add this figure to the amount the plastic rod on the gauge is protruding from the neck - this will give you your distance from the lands

 

If you are already shooting with an accurate load, then measure what the ogive is on your chasen distance and then deduct this figure from the known distance from the lands to tell you how far back you are shooting - I would guestimate somewhere between 120 and 140 thou back from the lands. All this talk of 5/10/20 thou back - Mr Lee has a lot to answer for - the problem is that most people dont know a rifle can easily have two or three sweet spots at considerable distances from each other. Charley, tell us how it shoots at your chosen zero range

To be honest it shoots fine i am not doing this to try to improve anything i would just like to know how far i am off the lands with this load which is 24.0 Grains’ of Re-Loader 7 behind a 39 Grain BlitzKing .

I have done as you suggested and worked out the jump it is in fact 157 thou off the lands and i have no plans to change this as it shoots fine. This is as near to the max the magazine will allow me to go.

Here is a 5 shot group at 120 Yds, so it shows you do not need to be right on the lands to get good groups.

Impressive Charley - looks to me like you spend time on case preparation and have a good cleaning regime.

Yes it's true I have spent a lot of time on case pep I feel it is as important as the powder you use, as is the cleaning of the barrel, in fact it is a combination of all these things as you well know, it can be frustrating at times but if and when you get it right it is also very rewarding.

Its just a standard factory chamber, so lighter rounds are shorter and so trying to move the oal out to suit the lands the bullet head will not sit into the case,

 

its the same in my 243win, 58grs 65, will not touch the lands... but stil shoots great groups,

 

if theres not an accuracy issue don't worry about it,

That is mighty impressive ! I am not able to get groups anything like that but then again I don't try as I mainly shoot foxes, but without going into the reloading element what do you use when zeroing you rifle ie do you have fancy benchrest or is this just off a bipod ? I zero just off my bipod and I can't get steady enough to shoot groupls like that.... what I guess I am asking is what is your secret?

Hi there well I do my zeroing off sand bags but I shoot off a bipod using a sand bag at the rear of the rifle, this is where most of you movement comes from if you use a bipod, It need not be full of sand it can be cat litter which makes it light to carry but it must be big enough to give you support ware you need it, My bet is it would improve you gropes no end.

 

Have fun Shootingcharley. :hmm:
