Thanks again all for your inputs. Jim ... I understand now that your test data is not readily available, no issue here. I have noticed you and Mozella both refer to trimming, chamfering and pointing as the process to follow. All I find on the internet for bullet pointing are bullet pointing tools which seem to address using a press and die to adjust/point (over simplified for brevity on my part). Are you aware of any available written data describing how to trim/chamfer/point and can you point me in the right direction (no pun)? Thanks again.
The best thing you can do, is measure, trim, measure, point, and try different things and test them yourself. Measure as many aspects as you can think of, of the bullet before and after trying to modify them(base to ogive, bearing surface, over all length, etc). You'll likely end up messing up a few, but you will find a point to where you're not changing the important aspects (distorting the bullet). Then shoot and test what you have done.
I am relatively new to it myself, but I have a barrel thats been inconsistent this year, and I tested the same load with trimmed, pointed, both, and its really come to life since I started. I have also shot reference groups with untouched bullets. I just wish I started sooner, but I know what my winter project will be.
Everything will start to make sense to you when you measure all the aspects of the bullets, do your thing to it, and re-measure and see how consistent you can make things.
EDIT: Also, there are a few guys here who still post (Matt Kline and Jim O'hara to name a couple that I have shot next to before) who really have a lot of experience testing, shooting, and winning.(And some setting records for more then 10 years) I know you clarified that you didnt mean to come off as attacking their methods, but we keep losing guys like this on this forum because of snarky comments. When these guys are giving up information, absorb every bit of it, and when something makes sense to you too, test it. Maybe it doesnt make sense, but test it. Then you too will understand. Some things will work for you, and some may not. It all depends on the level you are at.
