Roy Hunter 103's

[Dave Way]

Today I started base to ogive measuring some of Roy's bullets that I picked up last week. The results were so amazing, I had to share. I started out doing 50 and was going to stop. Before I knew it I had done 100, and then, all 500. 496 of the bullets were plus or minus .0005". 4 bullets were just outside this at .0005" shorter. .0015" total variation for 500 bullets is nothing short of phenomenal. I don't know how he does it, I'm just glad he does.



Longest.



Shortest.

Phenomenal! But you just wasted hours of your life... but then again so did I watching the college football playoffs

 

[dmoran]

Good ol' Roy ..... he's the man !!!

 

[Bc'z]

I'm betting those 4 will shoot a group.
How did they weigh?

 

[CaptainMal]

Roy likes praise. In fact, most all of us do.

Keep it up. He deserves it.

 

[Dave Way]

How did they weigh?

I just weighed 25 and they were 102.58 gr. to 102.66 gr. I also measured 10 out of each of the other three boxes. They were all the same as the first box. That saved me from BTO measuring the other 1,470 which is saying a lot because I tend to measure everything.

Id like to see you load up those outliers and see if they shoot in the same group as the perfect ones

I shot them as sighters last night Dusty, but they were so close to the same length that I doubt they would have shot any differently. I chose an arbitrary load and seating depth and printed a couple 4 inch 5 shot groups at 1K (30.6 gr. H4895 at +.008"). Both groups were all vertical so I'll adjust neck tension, but that wasn't too bad for a first test with a new bullet with no load development. They are going to shoot small.

These look like great bullets!

Have you measured the overall length? That and measuring the diameter of the bullet at the junction of the boattail and shank are the only sorting I currently do.

Dave what speeds were you at with 30.6 ?

I didn't chronograph but Vapor Trails run at 2,960 FPS with that charge.

Jason, there was .0085" difference in OAL but I have only measured 25 or so at this point.

Dave.

 

[6BRAckley]

.0085 variance is pretty good...curious to see how that will hold up as you measure more (if you choose to). I sort bullets into batches of no more than .003 total length variance.

What do you estimate the B.C. at?

 

[Stan Taylor]

Well crap I guess me an the ole Dasher an my Berger bullets might as well stay home.
P.S. give me the heads up when you are going to the club's I shoot an I will save match fees an maybe I can get some of them 103's.

 

[piaa1209]

Are you trimming either of the hunter or vapor trail bullets

Nah, this barrel is about wore out. New one going on this week. May not be a good one but I doubt that. Let me know how those 109's do for you. They look interesting. See you at the meeting in a couple weeks.

To answer a couple other questions, I have not trimmed and don't know the BC of these bullets.

Dave.

 

[Stan Taylor]

I am anxious to test as soon as we get decent temperatures.

Dave,

I've decided to shoot all winter now that I no longer sort bullets, lol.

Looking more like snowmobiling weather. You are a true diehard. Wonderful pic. Have nothing even close to that here in Pa.
