With these requirements...
The areas I will be hunting are coastal swamps, thick overgrown pine forests with cut downs and pine bays sprinkled here and there. Shots in this area range from point blank to about 300 yards and alot of the time they are on running deer that you end up jumping going or coming from your stand.
Yes I will be hunting some of the nastiest brush you have ever seen. Some times you have to get on your hands and knees and crawl up to 50 yards to get through some parts but after you get through you might find yourself in a pine bay that is totally void of under brush with nothing but large pine trees spaced pretty far apart where you can see from ground level 50 to 300 yards or so.
To be honest...you need at a minimum a medium bore caliber with a well constructed bullet...The problem is...your not going to get this...
in a easy to find caliber that I can find relatively cheap practice ammo for (I need the practice) that is very accurate in a handi.You want something that will put an animal down on the spot...buck nasty brush..and be flat enough & accurate enough for a 300 yard shot in the open...and still find cheap ammo to practice with...I only know of 1 that is like that right now...because of the ammo prices...and that's not guaranteeing it will stay that way...that would be a 30-06...Right now you can get Federal ammo at most Walmart's & Cabela's for under $10.00 a box
If you took up reloading...then there are a few calibers that would work well...I also saw a real nice Handi combo yesterday that I am real tempted to go and
put in law-a-way buy it...it's a 22" 444 Marlin/ 24" fluted 270 Ultra with camo stocks...This would give you the best of both worlds...and would be
almost a perfect combo for me...if it was a 45-70...then it would be IMHO...With my Nosler Partition loads both would be perfect for just about any situation...and both can be loaded cheaply to practice with...so too could the 444/270 combo if you got right down to it...I guess I'll buy it..My wife thinks I should any way...
