280 ackley improved 1@8 twist load ?

[NZ_Fclass]

Reloader 22 rocks in the 280AI - my guess is that 26 will too. Don't forget H1000. 1-8 twist works well, as do the 175/180g pills.

RL23 is probably the best powder for the 280AI, for F-class applications anyway.

For any application in my opinion.

I used to use 22 untill 23 came out.

R23 is a great powder but you can't find it anymore.

If i can run paper around the barrel. Does it still need opened up?

If you have the synthetic stock, it will flex with some pressure, especially with a bipod! I could run 2 one dollar bills up to the chamber taper and the barrel would touch the 'noodle' stock with slight twisting off the bipod!! Dropped 3 thou brass shim in the lug cavity and used 5 thou on each side just past the lug and staying low!! This raised the barrel about 30 thou at the stock forearm!! The target grouping improved with no strings!!

About one month ago, my son took a very nice dominant antelope buck, heart shot, at 450 plus with the 280AI in Wyoming!! It had 4 deep scars on the back, at the base of the neck from "LOCK UP" of horns!!!! He shot it using the bipod. The next day, standing and slung up, he took a whitetail doe at 150 to fill the freezer. He butterflied the heart with the 165 Sierra Gamechanger!! The shiming works on the 'noodle' synthetic stocks!!!!

aim small, HIT BIG!!!!

If you need to open up your barrel channel find somebody with a mill you use a Dremel and it will look like a 1 tooth beaver with a cavity

The barrel channel is not the problem. It is the flexing of the synthetic stock itself. Any downward pressure on the stock, side to side pressure of the stock, or any combination of the two will result in stock/barrel contact at the forearm end. I use the shiming method just in case I want to sell the rifle in its original form!!! Relieving the channel would cause a noticeable gap. The best method for opening the barrel channel is using deep well sockets and sandpaper!!!

If its a cheap SPS factory stock installing pillars and filling in the voids with fiber glass helps alot if you wanna spend the time, ive done it and they shot well after that.

Reloader 22, 23, are good powders for the 280 Ackley but don't overlook Retumbo especially if you're using 160 to 168 grain bullets.

Why would you put fiber glass in a stock that already flexes??? Fiber glass is designed to absorb energy by flexing!!!!

As a retired engineer, I'm will be setting up the router table, cut 4 grooves for carbon fiber rods, and epoxy bed, adding lab grade fine iron filings as a filler and strong binder, to the barrel groove!!! And the epoxy I have on hand is Marine grade!!!!! This is 10x stronger than polyester fiber glass and much more rigid!!!!

I have used the iron filing/marine grade epoxy bedding on 2 Remington varmint/target rifles with outstanding results!!!

NOTE:
In 1963, the Carl Gustaf factory in Sweden developed and Patented Epoxy bedding of the lug! Glass bedding (Polyester resin) started in 1965. I have a CG-63 with the PP number stamped in the epoxy bedding!!!!! And, that target rifle shoots circles around Remingtons. It also has a Norma 29.5" Palma barrel!!!

Because it stiffens the forend.
Have you ever installed pillars and filled the voids with fiberglass? Theres a big difference in a gunstock and let's say an application like a boat.
If you haven't done it dont knock it untill you try it. Will other things work like epoxy's absolutely.

Like a boat, there are places on the boat repair where polyester resin is used where you need flex!! Other places, like the transom and junctions of other parts require the 10 times stronger and stiffer epoxy resins!!! If you want stiffness and strength, go with epoxies!!! Adding the filings increases stiffness and strength!!!
