What's an Amax like as a hunting bullet? Also, my rifle has 1 in 11.25" twist and may not suit a heavier bullet such as a 208!

The amax at 800yards leaves exit wounds big enough to put your hand in. My 1-11 twist stabilises them but any slower might be pushing it

You are right there Cam, the A-Max just plain works !!!

What are they like closer in guys, say around the 100 - 200 meter mark?

leathel,has any one mentioned using someone elses scales?what if you scales need calibrating.hope that hasnr already been mentioned.

My 2 cents for what it is worth...

You have way overcomplicated things just keep it simple, put the bore scope away, don't worry about .1-.2 grains of powder in a case that big, & lengths or run out to the nearest .005, change powders, even primers especially with the fast IMR 4350, change projectiles try lighter BTs or Accubonds, if it won't shoot them it is beyond help, change brass, check all the simple stuff, scope, rings, bedding, crown etc, change to shooting 3 shot groups, don't worry about neck tension until it shoots, get some else to shoot it, it recoils do you flinch ?

It is very easy to spend heaps of $$$ on a rifle that won't shoot, instead of admitting defeat & re-barreling it.

The 5R is very similar to the Sendero, generally they shoot very well.....

The data I have found says the 300 win mag should be 1-10 twist like most of the Remington 30 cals which gives them an advantage over the Tikkas with the heavier projectiles.

I would be more concerned with your accuracy issues than problematic ES readings.

Yeah, look I agree Greg, with regards to my accuracy issues, the Chrony ES (despite the Chrony being set up only 3m from the muzzle) was really a "One Off" with that sort of extreme spread, most of my other strings are generally well behaved, it was just that "One"!.. The accuracy issues, however, I am very concerned about for that's the very reason I bought this rifle and all I'm getting is a "scant" 200fps over my ole Ruger MK11 in .30-06 calibre that's shooting 180 Grain Noslers at 2,800fps with an accuracy of no more that 1-1/2" five shot groups consistently, for nearly twice the weight in rifle! (Geeze there's a lot of sad faces in my camp!)

Um, now yeah, the second thing I agree with you is... that the rifle "Should" be a 1 - 10" Twist, however, interestingly enough I actually did a YouTube Video on my rifle when I first got it, and there I demonstrated (by use of a cleaning rod and insulation tape and a rule of some sort) that my barrel (despite it having 1 in 10" twist written on the outside of it) was actually, as fellow Internet users claimed, a 1 in 11.25" Twist! So I now know first hand that it definitely "IS" a one in eleven point two five inch twist! Go figure that! So, as I say, it may not suit the heavier 208 Grain Projectile!
