Your Winchester 70 (for which you did not list a caliber) is likely not the same as your 270 (which is a caliber, not a model number) If you look on the barrel (generally stamped right below the iron sight or just before the barrel joins the gun), you should find the caliber of the rounds for expected use.If you did not buy the weapons new, there is a possibility that one of them was re-chambered for a “wildcat” round. In that case a factory brass may be longer than what you need, preventing you from closing the action.Any competent gun store employee or a local gun smith can easily find the correct ammunition for your weapon.Remember….the model such as for example a Remington 700 is a model. That weapon is chambered for many different rounds but you cannot interchange them.

270 Winchester factory loads shoot bullets in the 120-150 grain range. Of these, 130 grain and 150 grain bullets are by far the most common. On the other hand, though it`s possible to find . 30-06 ammo shooting bullets weighing as little as 110 grains and as heavy as 220 grains, most .
270 WSM is 130 fps faster than the . 270 Win. with muzzle velocities of 3,100 and 2,970 fps, respectively.
Select shells that are the right gauge and length for your gun. Match the gauge of the shells to the gauge of your gun. For example, a 12 gauge gun takes 12 gauge shells. You CANNOT use a shell that`s a different gauge than your gun, even if the shell fits into the chamber of the gun.
The . 270 Winchester uses a . 270 inch (6.86 mm) bore diameter and a . 277 inch (7.04 mm) bullet diameter.
Typically, the heaviest 270 bullets are around 150 grains because that is all that can be stabilized in a 1:10” twist. However, if a faster twist barrel is used for a 270 rifle, it can stabilize a much longer, heavier and higher BC bullet.
270 Win. is loaded with bullets ranging between 130 and 150 grains with velocities between 2,900 and 3,100 feet per second.
Assuming that the rifle weight is consistent between the two cartridges, the 270 Winchester will have less recoil for almost every factory load when compared to the 308. This is primarily due to the heavier bullet weight of the 308. Simply put, lighter bullets recoil less.
270 Win. is still cooking along at 1,800 fps all the way out to 680 yards. That additional 100 yards of effective range is why many long-range western hunters have opted for the . 270 Win., and why many have stuck with the venerable old cartridge even as sexy new long-range cartridges have come onto the market.
Smaller shotshells (such as 20-gauge shells), if mistakenly fed into a 12-gauge gun, will slip past the chamber and lodge in the barrel, causing serious personal injury or gun damage if a 12-gauge shell is loaded and fired.
All shotguns that can shoot 3 or 3 1/2 inch shells can also shoot 2 3/4 inch shells. The only difference is how far down the barrel the end of the shell goes.
Bullet size and bullet weight are other important differences between the 270 vs 7mm Rem Mag. The . 270 Winchester uses . 277″ diameter bullets while the 7mm Remington Magnum uses larger .
I think of 150 grains as the deer bullet, 180 grains is the elk bullet, and 165 grains is the compromise. In . 270, the 130-grain load is the most popular and most commonly used for deer-size game, which includes sheep and goats.
Reloading powder for 270 Winchester
Traditionally, H4831, IMR4831, as well as H4350 and IMR 7828 are very popular choices for 270 Winchester. They give great speed, fill the case consistently, and are readily available.
First, the 270 Winchester uses larger diameter bullets than the 243 Winchester. Specifically, the larger diameter . 277″ bullets used by the cartridge have about 30% more frontal surface area (also known as cross sectional area) than the . 243″ bullets used by the 243 Winchester (.
For those reasons, the 270 Winchester is a quintessential deer and sheep hunting cartridge. The cartridge is not limited to thin-skinned medium game like sheep or deer though. Indeed, many hunters use the 270 Winchester on bigger game like black bear, elk, and even moose with a lot of success each year though.
223 Remington has a muzzle energy of 1,175 foot-pounds, while the . 270 Winchester has a muzzle energy of 2,729 foot pounds. Downrange, the . 223 Remington loses energy quickly, dropping to 947 foot-pounds at 100 yards and 469 at 400 yards.
Ballistics If you`re going for power, the . 270 Win. wins this race in a landslide. The taller cartridge can push a 130-grain bullet over 3,000 feet per second at the muzzle, producing 2,702 foot-pounds of energy.
Recoiling From Excessive Recoil
For many shooters the 270 Win. represents the upper limit of tolerable recoil. In an 8-pound rifle firing a 130-grain bullet 3,100 fps, the 270 will generate 18 foot-pounds or free recoil energy. In comparison, a 30-06 with a 150-gr.
On average, the 30-06 will generate 25 ft-lbs of recoil energy while the 270 Winchester will slap your shoulder with 20 ft-lbs force. Although the 270 Win does have less recoil, it`s nothing like a 223 Rem! Shooters will often report that the recoil impulse is different between the two cartridges.
Its versatility, accuracy, availability, and manageable recoil make it an ideal choice for many shooters. However, its limited bullet selection, barrel life, cost, and limited long-range performance are some of the drawbacks to consider when choosing this cartridge.
The ideal barrel length for the . 270 is 24″ (600mm). This length will typically give 3150fps with 130 grain bullets, 3050fps with 140 grain bullets and 2950fps with the 150 grain weights.
Guns fired with the wrong caliber can seriously damage the user`s hands and face. This is because debris from the gun may come flying off when it`s fired with the wrong ammo, and the pressure causes the gun to break apart.
A 4 gauge shotgun can be loaded with 3 to 4 ounces of shot. By comparison, the heaviest 12-gauge loads available are 2 1/4 ounces. A 4 gauge load will throw almost twice as many pellets as a 12-gauge.
The Bike Technicians Tactic Phase1 An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician’s tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities. Engine Technicians Tactic PHASE 2 A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.
