What diameter, length and twist would you recommend for the 28-30 rifle barrel on a Ruger #1 action? Thanks for your answer, Hank45

Book shows .285" diameter with a 14" twist. A 7MM barrel would be .284" but finding one with a 14" twist may be a little hard. Douglas has a 12" twist that should work http://www.douglasbarrels.net/chamberings/

Bartlein will make any twist you want including a gain twist so one might consider a heavier bullet than normal for wind sensitivity purposes.

Take a look at their T-Style Rifling

What weight bullet are you planning to shoot?  The factory loads were 120 grain, as were most of the fixed handloads.  But breech seated bullets or Pope style ML bullets were in the 135 to 140 grain range.  Plus there are 7mm moulds that go as high as 180 grains.  I have a Lyman 285221 that casts about 175 grains.

The real tackdrivers shot 135 grain bullets.

I think the 285221 and later on labled 287221 could be had in 7 different weights.  They ranged from 90 grs up to 175 grs if memory serves.

There are several top of the line mould makers that can provide you with a bullet design that is to your liking and more importantly they will fit it to your individual rifles requirements for accuracy.

There is nothing more frustrating than to have a new rifle not shoot and allot of blame is put on everything and everybody but the ill fitting bullet generally ends up being the culprit.

If it were me I would pick a bullet weight that I want to shoot,  have a barrel made to the proper twist rate to support it and then have a custom bullet mould made to fit the bore, groove and freebore of the chamber.
