Measuring Bullet Bearing Surface

[EagerNoSkill]

Hi All

Question about measuring bullet bearing surface.

I have bought, weighed and now measured several hundred Berger and Lapua bullets.
I am VERY impressed by the overall quality of the bullets - the weight differential is less than 0.6g out of 300 bullets


My question is what is the realistic measurement parameters since I still dont have the Ovenpaa/Spud device :shifty: (HINT)
I am using the Hornady Comparator with a digital dial caliper

In this case, for example, I partioned the bullets in .0004in segments

Like < 0.3740 0.3741 to 5 : then 0.3746 Plus

Any more and I get too few bullets and I doubt any real benefits
- any more time spent is better used to earn more money to be able to shoot more!


Any advice comments confirmations?

Thanks Spud

Your advice is always valued and followed 99% of the time - the other 1% is the "im a male and know everything" gene :-)

[spud]

after supper , crikey i thought you were more dedicated than that , watch whilst eating your supper

thats an order

[ovenpaa]

I have most of the parts to make another four (No DTI's at the moment) the new version has a revised design if you are interested and Spud does not have any in stock yet. I will need sample bullets to suit.

[spud]

can i have sme stock then david

[ovenpaa]

Sure, let me know how many and the bullet sizes, I may need sample bullets if it is something I do not use.
