Bullet stabilization, barrel fouling or breaking in?

1. What happens to consistency if you back the Projectile off the lands by a thousandth or two? 2. After ten rounds and cleanings any quality barrel should be broken in. 3. Stabilisation vs overspin? Since keyholing isn't apparent, under stabilisation isn't a problem. 4. How muck tighter consistency could be achieved with another Projectile? Sometimes fitting a square peg in a round hole has consequences. 10 shot groups 10 times display the actual consistency. There shot wonders are fine if you don't expect to shoot more than three shots, but in such circumstances the consistency of the single clean cold bore is more relevant. If one shot one kill is the goal, there isn't a fouling shot involved! If a 40 round match without interruption is the goal, the most consistent 40 rounds need to be found. Great 3 round groups that are not repeatable for 40 rounds are of no use in a 40 round match. Purpose needs a little focus! JMHO.
I see what you are saying.
I'm just scratching the surface with this rifle. There's under 50 rounds shot out of it, at this point.
I'll try to focus through the veil of my ADHD!😄

ADHD gets the best of us hahaha. All I know, is that rifle is going to shoot plenty good!!!
 
It's a fine line these days between spending a fortune on components and getting enough data to be valid. I am seeing more and more that finding the right combo of bullet and powder is most of the battle. It's seems when I do that load dev is usually easy and the load is very tolerant of minor changes. This is where the internet can help. Found out what the most popular combo is and look up some data. Pick a midrange load and start there. I like to shoot 8-10 3 shot groups with hunting rifles. 5-6 five shot groups. I shoot them at the same target. I do this at 100 before moving out.
 
Cajun's advice is spot on. It is amazing when you find the powder the bullet likes or vise versa, does not seem to take long.

Fourth and fifth shots heat up a barrel, where copper fouling can seriously degrade accuracy. Also, time extends the chances for wind changes in longer shot strings, which often are nothing more than an indication of how stable the air temperatures and wind are at that time.

Barrel quality from the foundry, heat treat, uniform bore dia, and bore smoothness rears its ugly head. Each barrel will have its fouling characteristics, and the Teslong bore scope will teach volumes keeping accuracy at its best where 1/4-3/8 MOA thrives.

A wind flag(s) will help you sort out flyers from wind switches and velocity changes. Serious shooters are slow on the uptake of the simple Physics that wind moves bullets.

180s have a lot of bearing surface, watch the copper in your barrel. Play with ballistic programs, there is a distance where 162 & 168s are offer less wind drift and bullet drop....don't outsmart yourself.

I have Wilson barrels in 6 BRA and (2) in 22/243 AI, they are great shooters but I had one that I would not chamber due to bore ID uniformity. The three Wilsons that I do have chambered are very smooth inside, more so than a very popular Cut rifle barrel brand. The Wilsons are MUCH smoother than a couple of Shaw's that I had a couple of years ago.

I will not comment on the issue of bullets going to sleep other than Aberdine Proving grounds took pictures of various bullet nose designs and bullet yaw for an Olympics 22 Rim fire Project.

Might be worth running a couple patches of rubbing alcohol then a couple dry patches after that, once you've completed your cleaning routine. For me that's seemed to greatly reduce the number of foulers I need to return to original POI/POA as well as "normal" accuracy.
I haven't heard of running rubbing "isopropyl" alcohol in a clean bore. Do you run dry patches through it to remove the water? I'm pretty sure rubbing alcohol contains water.
 
Back in the Day, IMR 4350 for 150 grain and 165 grain projectiles at approximately 2770 and 2625 fps respectively used to perform well accuracy wise. Just food for 🤔
