Yep!
When it gets beat up a bit I'll try a more reasonable color scheme.

Wow this has got to be the longest thread I've ever read! 113 pages if you print it, good reading for going home on the bus. Even followed some of the links to other threads. Read BB's elk & Tiger Stripes story again. Got me psyched for the upcoming fall!
It is a good thread and I have learned a bunch from it. So now here's a few questions.
<ul type="square">
[*]I notice the majority with 270AM's have 30 inch barrels + brake. Seen a few who have 28" + brake. Is it just personal preference?
[*]What are you guys estimating the barrel life is on a 270AM?
[*]I notice some have the rifle throated for one specific bullet (i.e. the wildcat 169.5). Is that more related to the preference of the customer, or is it a better way to go with the build?
[*]I haven't found anything relating to the design of the 270AM and how it's design came about? What did it start from and change into to become the 270AM?
I realize my questions are probably more suited for Kirby, but please anyone feel free to pipe in.
Really enjoyed reading this thread!
Cheers.

Last time i checked i had one of the 270AM's that had the most rounds down it, around 850 and it was still shooting great. I have since had Kirby re bbl it to a light wieght 270AM. BJ's had around 650 rnds down it and we have scoped the bbl and the throat looks really nice, better than his 6-250 with 1200 rounds down it.

[*]I notice the majority with 270AM's have 30 inch barrels + brake. Seen a few who have 28" + brake. Is it just personal preference?
<font color="blue">I had mine built to 30" as initially I wanted all I could get from it velocity wise, however after receiving it, I decided to tone down my need for speed and pick a decent velocity which would allow me to use it for as long as possible. THe 30" barrel also gives you some room to have it set back and cleaned up once the throat starts to get too crusty. The brake was installed on mine to allow me to see the downrange hits at 22X of the Nightforce. </font>
[*]What are you guys estimating the barrel life is on a 270AM?
<font color="blue">Mine was built to shoot mostly in hunting situations. I probably have around +/- 250 rds through it total. I broke in the barrel, then worked up a load for both the 169.5 and then the 195 Wildcats. As for a useful number, it would depend on the loads, rate of fire, and the cleaning regiment. Sometimes the cleaning can be as bad or worse on a barrel than the shooting is, depending on what is used and how often. You have to figure that in a standard .270 Win. load using 50 - 55 gr of powder, four consecutive rounds will generally get the barrel pretty warm. Most loads for the .270 A.M. use about double that so the consecutive round count about doubles the heat and adds up quickly on wear and tear. For my best groups, I generally do not shoot over three shots in a string. Besides, in a hunting situation, with this class of rifle, you shouldn't need more than that to effectively incapacitate just about any game animal, using the right bullet. </font>
[*]I notice some have the rifle throated for one specific bullet (i.e. the wildcat 169.5). Is that more related to the preference of the customer, or is it a better way to go with the build?
<font color="blue">When I ordered mine it was basically for one specific purpose, and that was to anchor a big hog at long range. I wanted something a little different, and the .270 A.M. seemed to fit the bill. I talked with Kirby extensively about what it would do, and how he thought I should set it up for my purpose, and must say that I have not been disappointed in the project. In that, I figured that the bigger the bullet, the better the hit ratio would be under hunting conditions,(enviromental factors). Yes there are a few heavy bullets out there in .270 but not many. The 140gr bullets can be screamed out at some very impressive velocities, however, this also shortens barrel life. My fireform load is using some old Nosler 150gr Solid Bases, that are running around 3450 fps and could easily go higher if I wanted. I also found that after I tweaked the seating depth they would shoot around 1" at 500yds so they can easily be used for hunting as well in a pinch. My main goal for the Wildcats was not necessarily to push them to the limit but to find a good load for each that could do what I needed and still not have to much holdover. After doing a lot of figuring, I came up with a top velocity for my rifle of 3250 fps for the 169.5's, and found that I could get excellent results at 3150 with the 195's. I could go higher with either bullet, but these suit my purpose in the accuracy and velocity dept, and have proven to be devestating on the hogs. </font>
[*]I haven't found anything relating to the design of the 270AM and how it's design came about? What did it start from and change into to become the 270AM?
<font color="blue">This might not be the first of it, but it does detail some of how it came about, I am sure that Kirby can fill in any remaining questions, 270 Allen Mag, Extreme Sporter Range test... </font>

Did you guys build single shots or repeaters? What was your reasoning for going with what you chose.

Slopeshunter,
The boys are getting you good information to your questions and I always feel its better to get it from actual customers then the rounds creater anyway, less bias information for the public.
But if you want any specific rifle information, feel free to drop me an e-mail at the address below in my signature.
Other then that, it looks like your questions are being taken care of very well!!

Slopeshunter,
My 270 AM has about 230 rounds through it. Most of them were used to learn how to reload for the cartridge. I've never paid any attention to COL and setting back shoulders before. Also I spent quite a few rounds shooting at long range before I was really ready to. /ubbthreads/images/graemlins/frown.gif Plus throw in the shots spent field calibrating a drop chart to the Mil Dot reticle then switching to clicking in MOA. My largest adjustment was/is to the fact that the rifle is accurate enough that I can notice atmospheric changes ("Hg, Hum, etc.) from range session to range session.
I went with the single shot for the following reasons.
- ADL stocks are supposedly a bit more stiff than BDL stocks.
- The glued in aluminum block is bound to stiffen the action at least a little bit.
- Not handicapped by magazine length and 'potential' feeding issues.
- Never bothered with flattened bullet tips.
- I like the idea of a single shot. If your prepared a second shot, if necessary, it isn't that far behind the first. If you have a spotter with you then reloading begins immediately upon firing the first shot as they can call the shot for you. At times I don't have a spotter, thus my expectation of seeing ALL of my own hits
- Oh yeah, I almost forgot. It was less expensive as the 721 bottom metal is not nice and I gave my BDL bottom metal to some fella in Slidell, LA. /ubbthreads/images/graemlins/grin.gif

Supermag,
No big game blood has been spilt with the 300 AX yet but this fall it will be. I have not decided what I will use on my elk hunt. It will either be a 300 AX or a 338 AX. I will take them both and which ever one I have in my hands when I run into a bull will be the one used.
I am currently waiting on a specially designed barrel from Satern barrels for my 300 AX that will hopefully work well with the thin jacketed bullets as well as the heavy jacketed bullets. When that barrel gets here I will do more testing and keep you up to date.
My new APS Raptor receiver is almost finished as well so I will be reviewing my new receiver here soon as well!!!
Hard to sleep at night with all this fun stuff, then throw a new little baby girl on top of it and I really get tired quick!!! /ubbthreads/images/graemlins/grin.gif
