Tipping and pointing bullets?

Take a look at the Bryan Litz testing on this subject in his new book "Modern Advancements in Long Range shooting" Volume II before you make a decision.

I dont know what Litz says about the subject, but can assure you pointing makes a difference. Some bullets or calibers, it helps more then others. There is as much as 12 inches elevation change at 1000 yards. That means they are gaining BC. The thing you need to be careful with is overpointing and distorting the bullet. Matt
 
Trimming meplats uniformly works for me.
I don’t do any other steps.

When I was using Sierra bullets, the meplats varied by vast amounts, that is the only reason I did it. The UGLINESS didn’t bother me.

Cheers.
:D
 
+1 on what Matt said, he is a 100% right. A lot justify not doing it because they are too lazy and others
that say it doesn't work because they don't sell the pointers or don't know how to use them correctly.
Some authorities are dead wrong, but they make money off it...... jim
 
As Matt said,

Trim a few bullets color them, and with all else the same(load/seating/etc) they WILL shoot lower than the untouched.

Point a few bullets color them, and with all else the same(load/seating/etc) they WILL shoot higher than the untouched.

The key is making them consistent. All of this is easily seen at 1k. I havent tested it shorter than that to know how soon it will show.
 
I use the Hoover trimmer and pointer. I'm in the early stages and very much a newbie on all things long range. But I can tell for sure my groups are getting more consistent. Especially after trimming and pointing. Wind and mirage are bad majic to me. Only trigger time will fix that.
 
Can you give a brief synopsis?
If you trim and/or point bullets the full chapter is worth reading. There is a one page summary and a one page recommendations at the end but I think it is worth reading the full chapter to fully appreciate the strengths and weaknesses of the summary and recommendations. If you are data driven, there is some good data however Brian says there is more testing that needs to be done since his data only represents a few bullets. I agree.
 
I feel like Hoover's approaches to both trimming and pointing are better than other tools & combos.
#1 their trimmer takes datum off the ogive, leading more toward uniform meplat diameters -than of bullet OALs.
#2 their pointers have the option of different profiles for different ogives -for lower pointing transition.
 
He also says annealing does no good. Matt
This is somewhat off the subject of the thread but if you anneal or are considering annealing I think reading the complete section on the annealing testing and the results that Bryan reported is worthwhile. His testing was somewhat limited in scope but this is the first time I have seen someone do testing and present data on this topic. I am not saying that other testing has not been done and the data reported but just that I have not seen any. I have seen a lot of opinions and beliefs reported which may be valid but not test data like Bryan presents. I think there is a lot more to Bryan's report than "does no good" and it is worth reading the full report if you are interested in this topic.
 
the wonderful and i assume extreme time consuming research done by Litz is all with sammi chambers and 24-26' bbl......it gives you some guidelines, but, i will assume if shooting F class 98% have custom reamers and 28-32" bbl....so unfortunately the only way to know is to spend lots of time and $$ of our own to get our own results with these "custom" set ups and i dont have the time to do test like he does, so i use it as guidance or reference.....unless i can say i can read the wind perfectly, none of this pointing/annealing probably matters as much as wind reading

AMP has an interesting series of articles on annealing (more on the science of it than the benefits when shooting):

My own testing concerning annealling shows tighter SDs and smaller groups than without annealling, so I continue to do it.The further fact, that I am getting at least 12-14 loadings from casings without cracking, means I will continue the practice.
