Any Gain twist barrel shooters?

[R.J.Bruce]

Another thing to remember is that both the Colerain, and the Hoyt, gain twist barrels are designed with deep grooves for a patched ball.

Most, if not all, of the data on the web is referring to a gain twist barrel with shallow, square bottom grooves designed to stabilize a long-for-caliber lead conical.

If a shooter is going to try shooting a lead conical in a Colerain or Hoyt barrel, then they will need to protect the base of the bullet, as well as seal the deep round bottom grooves, with some form of an over powder wad.

According to Scott, he has one customer that has taken a .58 caliber Colerain gain twist rifle to Africa on safari, and used it with great success against African game utilizing both patched balls, and lead conicals. The 1:36" twist at the muzzle will stabilize all kinds of bullet weights. The limiting factor will always be the human shooters ability to handle the recoil.

Boredom has come but I wanted to find out about Gain twist barrels pros & cons

In ball shooting barrels it has no real advantage because the bearing surface is so narrow the change of pitch contacts that it doesn't effect much how ever in a conical shooting barrels it will help strip the paper patch if used ,more uniformly. It also tends to dampen barrel oscillation as the progressive pitch change on a bullets much longer bearing surface increases pull on the barrel linearly dampening harmonics.
