On my way to Hell in a handbasket
I was approached by a co-worker who was wondering about the accuracy of the AIA M10 series, available through a number of dealers including Marstar. He's looking specifically at the M10 No. 4 Mk IV version.

I have worked on more Longbranch No.4's than I care to mention, but have no info on these AIA's, including quality or accuracy.
Can anyone pass-on any (first/second hand) info that might be of help to him?

I'd hate to see him drop over $800 when I could get him a very accurate and original No. 4 Mk 1* in .303 for a whole lot less.

Thanks for any info.
 
Forgive me being a NooB over this as I have never thought about it, but can use regular .308 Winchester ammunition? :confused:

I'd like to try one someday as a plinker/hunting rifle.
 
You can use either commercial 308 win or 7.62 nato milsurp. They like handloads, tailored for the individual rifle even better.
There have been some very good deals in the EE on some of these lately, with very low round counts. I love my heavy barreled model. bearhunter
 
I just got mine yesterday.
(skeet skeet)

It is solid. Beefy. As previously stated, fit and finish: top notch. the pics on marstar dont do it justice.

Im taking mine out to the range this morning as soon as theres enough light. ill give a range report tonight.
 
I did a report on my first AIA back on 28-viii-06. You can read it on or about p. 48 on the milsurp thread. There are a couple of other good reports on this rifle.
It's a pretty solid bit of kit.

Thanx for the info! :)
 
The no4 mk iv is an excellent shooter I have shot mine at 200 yds. with a parkerhale ph4 peepsight and it is accurate. I also shoot at 500 yds with a bushnell fixed 10 power target scope and it is very accurate. It likes handloads.
 
With respect to handloads - are there any signs of incipient case separation observed? Pretty common with original Lee Enfields.

That happens quite often with the milsurp LE's in 303. Because these rifles have generous chambers and cartridges headspace on the rim, they tend to stretch excessively on firing. These brand new AIA's are usually issued in .308 (headspaces on the cartridge shoulder datum line). Using proper SAAMI chambers, i.e. very little case stretching, ergo: no typical 303 head seperation issues.
 
As I have stated before I seem to have never had a case seperation despite having 4 .303s from different makers and handloaded for all of them at one time. I keep the seperated case tool in my cleaning but in 10 years I havent had to use it!

You just know the one day you leave it home on your workbench... It's a moment when tools become more like good luck charms. :D
