Thread: Whats this about?

.300 Winchester Short Magnum

"Readers are however advised against adopting suppressors and brakes in the lax fashion that is very common at the time of this writing. Without close attention, both brakes and suppressors can be highly detrimental to accuracy and barrel life."

I just reading through this and want to know what he means by without close attention. what close attention should I be looking at?

People doing a poor job of threading the barrel?
Neither a suppressor or brake should affect the accuracy of a rifle, but poor fitting could.

What does a brake do to effect barrel life?

You needed to read the whole paragraph Toby. He answers your question. I cant comment on wether he is correct or not though. Although my 300mag certainly gets hot using the suppressor.

"Readers are however advised against adopting suppressors and brakes in the lax fashion that is very common at the time of this writing. Without close attention, both brakes and suppressors can be highly detrimental to accuracy and barrel life. Both suppressors and brakes can cause heavy carbon fouling which can decrease chamber dimensions, increase pressures and lift velocities over the course of a shooting session. Over barrel suppressors trap heat and during rapid fire with light weight barrels, ruin extreme velocity spreads. Winter developed hand loads can produce severe pressures in the summer during rapid/repeat fire. Muzzles can be completely destroyed via moisture condensing onto carbon deposits, causing severe corrosion (including on stainless steel) or in other instances, causing a swaged burr at the muzzle. Both brakes and suppressors are excellent, extremely useful tools but should always be utilized carefully. With either addition, the shooter must be vigilant with both cleaning and shooting methods"

He is claiming that brakes increase carbon fouling. He says the carbon decreases the chamber dimensions, and thus this increases pressure.

Wouldn't have thought the cleaning regime would be any different.
