The 30-30 has been around for a long time for a good reason, it works. It is still very popular East of the Mississippi. Most shots at deer are under 200 yards, the effective range for deer. It has even been used on Moose with acceptable results, just make sure you place the right bullet in the right place at a reasonable distance. It does not dislocate your shoulder either. 12 year old kids as well as the experienced person at 82 can use it with confidence. In the Handi, you can load pointed bullets and extend the range a little if you need it and is one of the most accurate loadings to boot. What is not to love, indeed!
Good Shooting and Good Luck
