Depends on your barrel and your grip. Mine is a 16", but tapered and rather pencil thin. If yours is a bull barrel, it would be better. And my grip is the Competitor, as the original gun in .30-30 was intended for IHMSA, but the grip is horrendously lacking for .45-70. A different type, or a Pachmayr would improve it. I took mine to Magnaport Intl. to have a full rifle job done on it, but to no avail. Best I've done in a session, even gloved, was 15 rounds. Before Magnaporting, it was 3. It's a hand grenade, and I don't shoot it anymore.Wonder how a both barrels at once on a DT 45 would compare with my T/C Contender 10" 45-70? That one gets my attention enough that I got some gloves to wear when I plan on shooting it more than 5 or 6 times in one session.
