Is that going to be the same for a straight 280 also? I'll probably have to be upsizing .270 brass or have to order .280 Win (nickel) brass and then fire form them to go .280 AI. Unless you know of a source for good .280 AI brass??Quote:

I've never had a straight .280 so can't say. You would have a better chance seating a VLD long though than a conventional bullet IMO.Quote:

I’m not a fan of nickel plated brass. Why? The nickel plating can flake off especially during reloading etc....the nickel is very hard and can scratch the bore and chamber.
VLD bullets vs a regular or just say different bullets....to get close to the rifling you have to play with the seating depth. VLD’s typically because of the longer pointer ogive you will seat the bullet out further in a given chamber to closer to the rifling.
If you want make up a couple of dummy rounds of where you want your bullet seated. Keep one for reference. I then send one to a reamer maker like JGS and ask them to make a chambering reamer to match the sample round. Then you can get it the way you want it.
For a few years back around late 90’s I ran a 280AI for some of the local sniper rifle matches. I shot the 168SMK for 300 yards and less and the 180 VLD’s for anything past 300 yards.
The Nosler brass Frank mentions is top notch with that being said the Lee FL die I had would not bump the shoulder. I trimmed the die bottom and got it to work but couldn't get the bottom inside smoothed out enough to not scratch the brass.
I sent 3 fired cases to Redding and they sent a FL die that worked with my chamber. They said it was a Sammi chamber so the Lee die was obviously pre Sammi.
I got the rifle for payment in moving some shipping containers and it was an early 80s Remington 700 with a Shilen barrel on it. Not my favorite rifle but it's kinda grown on me.
Trimming the die bottom is one way 6.5savageguy. When I think something like this is happening where the die doesn’t seem to be sizing the brass enough or cannot get it to bump the shoulder....take the shell holder for the press and take .015” off the top of it. That’s usually more than enough to give you more adjustment down on the die.
We had to do it for a local customer (from IL) a few months ago and I had to do it for my 6BRA. I took off .015”. Needed about .009” to .010”. Once I found how much I need to bump the case about .0015” to .002”....that when I go to set up my die I put a .005” shim on top of the shell holder and run the die down till it bottoms out on the shell holder/shim and then tighten up the lock ring.
I’d rather mess up a $6 shell holder then to mess up the die and have to send it back.
Even though the shell holders are some what hard I have no problem putting in the collet of the Hardinge lathe and can just face it off. Other option is to put it in the surface grinder. Either way will work.
Thanks Frank,Quote:

Thanks again for all the info guys... If I am going to go down this road I'm going to put it on my Savage 111 action (5 years or so old) and order a CBI already chambered. While I do understand how to hand load and seating depths, I don't want a big headache in the reloading process. I understand the basics but I'm nowhere near an expert... More of a plug and play guy myself, just not so much that I am ok with running factory ammo.
I've had great results from my other builds using CBI barrels, I was just thinking this one would have similar results.
