I had let it build up on me a bit and did not realize it until I ran a borescope in the barrel. ( I was really impressed with how this barrel is holding up, the throat isnt bad at all considering how much powder is being burned)
I am not seeing a 1.1 BC but upon some further use of the hats out to 1400 I settled on .96 at 200ft above sea level. I am not using multiple BCs and this is based only on my drops at various ranges plugged into exbal. I did bust two gallon milk jugs on two consecutive shots at 1400 yards a couple weeks back. Kirby builds a heck of a rifle....i guess RG does a pretty good job with those bullets too.
Someone who knew more about this stuff could probably fine tune the numbers better, but having my elevation within a couple inches at every yardage I shot out to 1400 yards is plenty good enough for me.
I want to hear the results of any long range matches yall shoot.
I got lucky in that my zero was exactly on vertically at 400 yards. Additionally, the gun groups the load under .2" at 100 yards and that helps too. The ES on the speed is way under 10 fps and that helps too.
The drop I initially quoted was the drop for the lowest bullet impact in the group... Specifically it was the worst case scenario..... I would rather folks find out for themselves how good they are when you sharpen everything up and get all the variables down to an absolute minimum..... For now I use 1.0 for the BC...... I let everyone else crunch the numbers and post the 1.1s. My flak jacket nor my fire suit is thick enough to withstand the response had I posted 1.1 for the BC.
Yes, I did leave some accuracy and BC on the table that can be further tweaked and evaluated later when the 86 lb 1000 yard Kelbly bench gun arrives.
As far as the gun is concerned, it is a hodge-podge of talent that put it together..... Allen Hall made the action, John Lewis chambered the barrel and I did both the bedding work and designed the reamer. It shoots fairly well for an old hunting rifle with about 1200 rounds down the tube that had both the chamber designed and bedding job performed by an amateur (me)......... That is a good example of how easy it is to put together a good shooting gun when good components are used.
While I am at it, I wanted folks to know that the bullets I shot were not weighed or sorted in any fashion. I just dipped my hand into the box and used what I pulled out....
So in other words, everyone else's results should be more impressive and better than mine.
On the matches, the gun will not arrive until early May and who knows when the big rest, rear rest and dies will be done..... We will be farming during that period and working up loads when everything is available.... Once the the loads are worked up for it and all the accessories are completed, we plan on campaigning it for as long as we can...
If RG will pay the expenses and all is working well with it, I hope to be ready for the World shoot up in PA this year..... That would be a very good international stage to have a "coming out party" for the bullets.
