3 identical factory rifles

So I have the opportunity to have 3 Howa Mini 223s here, all with 20' light barrels. I'd like to shoot them as a set and establish just how they shoot with various ammos. I'll use groups of at least 10 shots at 100M and using a variety of factory ammo and reloads. I'd like to explore a few things like barrel heating (fast groups versus slow ones), accuracy and one rifle will have a variety of tuning tweaks etc.

I'm interested in ideas on what sort of tests would interest people. I'm not a scientist so although I'd like to minimize variables, the results might not be that useful, just sayin!

Chuck a very unstable/ borderline unstable load load and see if all three behave the same.

Try different barrel break-in methods.

Whatever you do, shoot a 10rd group with every ammo type, keep clean and clearly labelled targets, and present the results in this format - what % of loads met what performance

Attachment 280564

Boat tail vs flat base everything else the same... Ten round group of liqourish allsorts loads to see if all three behave the same,one may spray the other cloverleaf.

10 rounds of the federal blue box each

None of the 3 are new, so break-in is a bit moot sorry. They are all however low round count

Haha, that was on my list for sure!

If you went 7-7-6 you could split a single box lol.

Speeds will be interesting.

Start a "Give a Little" page.

Over daybag with firm hold. With bipod firm hold,with bipod off hand on heel of stock.....it's 223 so shouldn't change much lol

You could try different cleaning regimes.
1.daily carbon + 100 round copper;
2. Carbon only then a protective oil.
3. Daily Anti rust only no solvent.

One thousand rounds later .....

Or allocate one to just a boresnake…
