115 Dtac ogive

[Jarrodb1975]

If anyone gets some free time can you measure the ogive length of a 115 dtac? Preferably with a Hornady comparator. Just trying to get an idea of the variance that’s out there. My lots are .758.

Just did a random 10 count. 8 were .759. 2 were .760

Thanks. Did u buy the lot recently?

 

[Lunchbox27]

Negative. Maybe 6 months ago

Here’s my BTO and lot numbers. No idea how old of lots they are as I bought them off the px

 

[Jarrodb1975]

That’s a lot of variation. I guess when I get a new lot my load will have to change. Believe I’ll give the new ring nose a try.

I’ve been through several lots. I always slightly adjust but accuracy is always good. I shoot to 1450. I can’t blame any misses on the bullet

I bought a box a couple weeks ago I can measure the BTO if you need it to see what the variation is.

 

[Jarrodb1975]

I would appreciate it.

10/4 buddy I’ll be back home directly and I’ll get you a measurement.

 

[Bb214]

I measured 5 of them and they all measured .752

 

[Jarrodb1975]

Looks like a .010 difference is normal. Wander what it is on something like a Berger 105 hybrid.

 

[Jarrodb1975]

Probably be a non issue as your throat wears as long as they were longer.

Just keep in mind the +/- for everyone's different calipers, not to mention the Hornady comparator inserts....is probably not insignificant.

But, lot to lot variation is certainly real. For the Berger 105s I find them very consistent within lots, but did see close to 0.010 difference between my last two lots.
