I'm getting the mil/MOA conversion down pretty quickly, but it's still just a little odd seeing .10th mil clicks vs. 1/4 MOA. I AM loving being able to see misses on the mil reticle and not have to convert it back to MOA to make an adjustment on the turrets. Shooter's already been converted to MILs for this rifle.....

Yep

I would tell you how a 105 A-max would seat but apparently I sold them and cannot remember doing it.

They're only .013" longer than the 105 A-Max, can't imagine that the ogives are much more than a blonde CH different?

If you have a bullet comparator, have Eddy give you the base to ogive measurement for the scenar and you should be able to load an Amax to the same OAL and make the comparison. That should tell you if it will work or not.

How does the 3-9 SS do at longer distances without parallax adjustment? Non-issue?

Wish I had a comparator around, that'd make things easy. I do believe Scenars have a longer ogive than the A-Max, so the 105 should work from the box pretty handily. Maybe Eddy will find an A-Max or two and give me an idea.

I shot the SS 3-9 at 900 today, and I will say that the reticle was a bit hard to use with the way the sun was shining. Very clear and bright though.... might have to mess with the focus a bit and see what happens. The no parallax adjustment doesn't bother me at all.

Do you have a way to measure base to ogive on a round loaded to the dimension you want? You need to get one of those sinclair nuts for measuring if you do not have one.

Take a steel caliper and set it at bullet diameter. Score the bullet at the ogive and then measure the distance to the score mark. Can't take credit for the idea. Mule Deer's, IIRC.

Got a few measurements, but I don't know how good they are...

I ran out in my shop (Well limped my crippled up arse out there) because somewhere in the back of my mind I remembered I had another 243AI out there. I checked the twist but it was a 10T as well frown

While out there I took some pics of that 243AI and of the bullet along with some measurements that could help you out. The little piece of barrel stub on the bullet is one of the greatest reloading tools ever. I have started making one for all the guns I build.

Here is that 243AI cute little thing but it needs a shortened action screw. It has a pillar in there that has a bolt holding the gun together, the screw hanging out is just hand tightened into the screw that is halding the gun together.

Here is the dummy round inserted in the doo dad after I spun it to make some marks on the bullet.

Here is a pic of the dummy sitting in a SA mag box I keep around for size checking.

Here is the bullet being measured with one of those sinclair nuts on it. Subtract one inch to know base to throat measurement.

Here is the COAL of the dummy round with the 105 scenar.

My 105s are at 2.18 when seated to 2.805" COAL. Does that make any sense at all?

Yep. If it will feed at 2.805 you should be good to go.

Did some calculating and it looks like that reamer will jam A-Maxes at 2.815".

Damnit I've wanted a 22-250 for a while but all this 243 ai talk has got me wanting one, good new is the donor is staring at me, leaned on the wall right now. Is It bad to want one with a #3 in an Alaskan at 23 inches

Sounds about perfect to me.....

Kenny, any idea how close 2.768" puts the ogive to the case mouth?
