For those shooters interested in improving the consistency and accuracy at mid to long range shooting,
bullet metplat uniforming can produce remarkable results. Trying to minimize the mechanical variables,
the "thing" that does the actual "flying" needs to be as close to identical to reduce "hit deviations"
Too often reloaders "due diligence" on brass preparation,powder selection and charge weight,neck tensions
and seating depths but "trust" that their bullets are "match" and load them right out of the box.
Just because the box says "Match or Target" doesn't mean they are ready to shoot.
Last winter,during brass and bullet prep (shooting downtime for me) as an example,I sorted 3000 Berger
Match Hybrid (same lot). For my first sorting I elect to measure Overall length (base to tip) .
The resulting Bell Curve was very wide and had a spread of over 50 thou.
This deviation may not show up or make a difference at short ranges,but it will definitely play havoc with
you at distance.
Bullet sorting is just a given these days for Long range accuracy nuts.I addition to overall length,metplat shape
,size and consistency play an important role.So begins the shooters ability to "improve" the actual factory
bullet with metplat treatments. Bullets can be trimmed to same lengths and the overall size of the metplat
reduced by pointing.NOT in all cases will you be "giving up" BC but actually gaining.
In addition to this ,sorting to weight,base to ogive,etc. all play a role in launching the most identical bullets
possible.This is not to say ALL your bullets will be exactly the same.When shooting ,only those that are being shot together,
"string of fire" need to be the same.I end up with "groups" of bullets that are to be loaded together so I can control
deviations.
There is a reason I've posted this note in reloading.I was going through my kit getting started on this winters projects.
I found a Whidden Metplat Kit (multi caliber) that is excess to my needs and have posted it in the EE.
If you are considering taking your reloading levels up another step,I suggest considering in addition
to bullet sorting, bullet profiling.
Just a self serving FWIW note....
Oh and as an afterthought for those that are sorting and after the 1st hundred or so are not seeing much difference...
it's at that point you are sorting NOT to be sure all are the same,but are sorting to find that 1 or 2 really out of wack
bullet that would have ruined your day had they been included with the rest.( It's too easy to stop sorting when all seem to be in order
half way through the lot)
