Tuning a firearm

Who here has done it? How many have you tuned.
I refer to the ultimate performance of a particular gun. not make, model or caliber.
I have 2 out of 20 some odd that I have tuned.
This requires hours and hours of time. The monetary investment is limited to the gun, optics and dies. Then it is like marriage. Time is the most critical investment.
What grain of bullet does she like? Which powder? How much? How close to the lands of the barrell do we start? Over all length of cartrige. On and on.
Lets tart with my cheapo.
#1 The .223 New England break open with Tasco scope.
Less than $200 American. Accurate to "say when".
Off the shelf, cannot tolerate anything over 60 grains. I do not know what twist it has. I do know from hundreds of rounds, Remington is a dirty word to this rifle. Sierra and Nosler are like magic. Powder, I have been gone from home too long. If you are interested in the exact load, say so. It boils down to, this was a piece of shit rifle/scope combo until I "handloaded" the correct combo. Trial and error. Now, instant gratification out to 250 yds. 40 grain sierra match.
It just will not stabilize a bullet heavier than 60 grains.
#2
The Ruger 77 mkII in 243 WIN.
I had a Browning BLR in .243. I had convinced myself that the 6MM or .243 was the ultimate for Texas. Most of this info came from the Speer reloading manual from around 1980. Legal game in my region was easily brought down by the 6. Hours of research led me to believe the .243 Win. was more accurate than the Rem 6. I do not, nor have not owned a Rem 6. Opinions are what I offer. I traded the BLR for a 77MKII and Simmons scope. The vows were complete. It was months before she even told me what she did not like, much less what she liked. After much trial and error, she divulged her secrets.
The particular load has been reliable on 35 lb feral pigs at 375 paces and coyote to 20 yds.
The ballistics defy science. Get hair in the crosshairs and squeeze the trigger. Something falls everytime. 9 point at 250 yds. Best venison I ever had. He never new what hit him. Fell in his own flesh blown out the side opposite of me. Then I killed 2 coyote off of him before I got there. The Ruger is mine for life. The H&R can be had.

The truth, the whole truth and nothing but the truth!

You can't reload rimfire anyway. As far as selecting bullets for loading, you can determine which weight range to look at based on the twist. If it's a fast twist for that caliber, go heavy, if it's a slow twist, go light. In .223, for instance, my wife's Remington varmint rifle has a 1 in 12" twist, so 55 gr and below is going to be the best choice. My M4 has a twist of 1 in 9", so anything from 52 up to about 69 gr will be suitable, and many of the M4/AR rifles have a twist of 1 in 7", so anything 62 and above will work best.

tuning in

I am in the process of tuning my MAS 49/56. Bought a scope mount, attached a 4x10 Tasco.
I am feeding it 125 gr ballastic tip rounds. Working on the amount of power now.

If a man can make you mad just by talking, then he is far brighter than you.

Okay, good.

1 in 9 is a good all-round round rate of twist for a 223. The weights you are most likely to find in bulk practice ammo, 55 and 62 gr, are both within the useful range for that rate, so plinking won't be a nuisance if you decide to stretch the range a bit.
