I have the hevi-shot model and with the old Rem. hevi-shot in my Win. 1300 it is much better than any prior lead loads with the old factory full choke. I don't care to shoot beyond 40yards or so and I had a reliable 35 with the factory choke, but now have an excellent pattern to 40 and around 100 pellets in the 10" circle at 45yards. Many people on this site have posted much better results with higher quality equipment, but I found the undertaker helpful at a good price.
