20 Νοε 2008 · Wondered how good ER Shaw barrels were. What kind of accuracy has been gotten out of them. Notice that they only do 1 in 8,10 or 12 twist in a 308 Cal. Will the 1 in 8 work for 208 to 240 grainers or is there gonna be some problems with the twist????
13 Σεπ 2018 · Displacement hardens the bore, which makes it more durable. As seen in benchrest records, both types of rifling can produce great accuracy. Shaw barrels are mostly button-rifled. 3.
21 Ιουν 2017 · Many barrels with common over bore used by LR shooters have 1000-1500 rounds life. BR tradition would have thorough cleaning every 10-20 rounds and then needing 1-3 foulers IMO cut down on cleaning till it actually meaningfully effects accuracy.

28 Νοε 2020 · My Shaw barrel in 6.5 CM was a copper mine. It shot terrific when clean, but accuracy went south as it coppered up, and it did that very quickly. They make a decent hunting rifle, but not so much if shooting groups in targets. Use it for what it was designed for and you'll be quite satisfied.
27 Ιουλ 2012 · Mike’s program predicts barrel life using five variables: 1) Bullet Diameter; 2) Powder Charge weight; 3) Powder Heat Potential (KJ/kg); 4) Pressure (in psi); and 5) Bullet Coating (yes/no). Mike provides a table with Heat Potential ratings for most popular powder types. The user needs to know the pressure of his load.
25 Δεκ 2005 · Found this Excel spreadsheet on calculating barrel life. It's pretty interesting in that it uses popular powder's heat potential in its formulas. It's a SWAP; Scientific Wild *** Prediction; not an exact number of rounds a barrel will last.
