Seneca Big Bore Light Hunter II, .45 cal

A well placed shot would but it doesn't meet the fpe requirements of a lot of states. Texas has the lowest requirement (215fpe) and most other states with requirements are 400fpe. This gun meets neither

Yes the end of the barrel is threaded

Same

Yes

Both calibers can shoot airbolts. The 50 cal is best for large game. The 45 cal will still do the job. It does not have quite as much muzzle energy.

.456 will give you your best seal and best results.

Actually, it uses .458 diameter which would be the same as a .45-70 rifle. You can get many lead in HP, Round nose or flat nose that should work. Pure lead will expand better though at low speeds. Check out Mr. Hollowpoint online for nice big soft hp's that perform well on deer/pigs.

.457/.458

Absolutely. Check out the highroad on YouTube. They have taken cape buffalo using the arrows. Check local laws though, because you cannot use bolts during archery season in many places or at all in some places.

It's actually .458 which is the same as a .45-70.

Yes, they make bolts for .50, .45, and .357

Ultimately, it will depend on your take on what's easy and what ain't. That said, a 244cc tank ( like the one on the 909s) is very doable, but I tend to fill to 2500 psi with a tank and top up to 3k psi with a Hill pump. Filling a 500cc tank from empty with a pump will be a workout but people do it. I like my method, fill to 22k-ish on a tank, shoot it down to 1500 or 2k then pump it back up to 28 or 3k and shoot more. I hope this isn't too vague and that it helps.

Having plenty of experience hand pumping my Marauder to 3000 psi, I can't imagine that the 500 cc tank on this would be any fun at all. Unless you're Hercules, you really should have a hpa tank or some filling method other than a hand pump.

Too many unknowns here to give a intellegent answer but why would a person want to pump this gun's 500cc tank up by hand?

If you intend on shooting more than ten rounds per session invest in a scuba tank or similar.

Depends on fill pressure which I do not see. If it is like 3000psi not to bad if more like 4000 starts to get real difficult.

NOT! Better to get an air tank. There are scuba tanks, full are at 3000 lbs so after a fill or two, no more complete fills available for the rifle. There are DIN valved high pressure scuba tanks. A 100 cubic foot 3500 psi tank will give you plenty of fill ups, and the ate the smaller scba tanks, 4500 psi, up to 100 cf that would super please me, except for 1; their cost, and 2; very hard to find a place to fill them. Then there are the small gap, 4500 psi tanks with regulators. The regulators van be a great safety feature as they can be set so that you never over fill your gun. Still hard to find a place to fill them, and still $300 plus. Hand pump will require 100's of pumps to fill the rifle. You have to exert force both on the down stroke and up stroke. You can not pump fast , it will over heat and ruin the seals. Many PCP guns can not be filled from a hand pump unless there is some pressure in them. Pumping is quite a work out and you would end up spending 3-4 more time pumping than shooting. Plus about every 50 pumps it pays to take a five minute break to allow the pump to cool.

This is more a "hmm" than an answer, but I use a pony bottle to fill my big air consumers in the field and, referring to the actual answer above, I'm * pretty sure * that if you swap out the air inlet fitting with a Foster fitting you will beat that bleed- off of tank air when you bleed your hose prior to disconnect. I hope I'm right, and this helps, cause this is my next airrrifle.

Suggestion, you'll need more than a buddy bottle to refill. Too much work for a pump. Check the state for reg.'s on PCP hunting. You need the gun for the game, you need the lightweight refill tank for the field, and probably a scope. you need Practice You have alot to get used to in sighting in a .45, it's loud and pwerfull. You need practice and probably need a compact scope so sighting in will be necessary for accurate kills on big game.: so you need the PCP bottle that carries 4,500 PSI for refills. (yes you need to get that refilled as well so either get local fill help at a scuba shop or get the Shoebox compressor.) $299 for the tank plus refill cost on it or see accessories for shoebox compressor. get a compact scope, see accessories - scopes buy affordable - call them for suggestions in your price range. Be prepared so you don't get dissappointed with your PCP. You want to kill what you aim at so you need practice, a pump will wear you out. This handy carbon fiber tank is small enough to tote around in the field in your backpack while hunting or eliminating pests. Easily fill your air rifles and pistols with the easy on/off quick-disconnect coupling. If you shoot field target, this will take the place of a buddy bottle. Since the tank is filled to a pressure of 4,500 psi, you'll get a lot more refills to your 2,900 PSI PCP rifle than you would with a buddy bottle. More refills, less hassles, no pumps and no heavy tanks! Features Carbon Fiber Tank Max Fill Pressure of 4,500 PSI Regulated To 2,900 PSI Output & up to 10% 90 Cubic Inches Only weight 4.10 lb . 4.50 Inches Wide 13 Inches Tall [Top of valve] Includes: Fill devices with female Foster quick-disconnect fitting and Carbon Fiber Tank (call them to fit the Sam Yang .45 500CC)

There are two methods of filling the air cylinder on the rifle. The easiest is the use a scuba tank and purchase the optional regulator that simply pushes on to the front of the gun, open the valve and it fills. you must be quick when bleeding of the residual pressure in the hose to keep from losing pressure. The second is to purchase the optional hand air pump. I have yet to use this method, but it sure bets lugging around a 60# air tank when in the woods.
