Really only your rifle can answer that. Some rifles like T-7 some hate it. Some rifles get little or no crud ring some get a hard crud ring so bad they can hardly load the second shot. Most of my inline rifles like T-7. It shoots sabots and conicals well. It is easy to clean. Very powerful. And makes a nice smoke cloud without the stink. It also washes out with simple water.

It has been know to cause serious crud built up. So use a witness mark when you load. If shooting sabots, swab often, and keep an eye on your breech plug. If you shoot it in a cap lock with patch and ball, check you patch. It like to burn them up.
