The exact .35 Remington bullet diameter is 0.358 inches, which converts to 9.09 millimeters. While .35 Remington ammunition is available with different bullet weights, the cartridge’s nominal projectile diameter remains exactly the same across all factory loads. This measurement refers specifically to the width of the bullet itself, which differs from the internal dimensions of the barrel. Specifically, a standard .35 Remington firearm utilizes a narrower bore diameter of 0.350 inches and a groove diameter of 0.358 inches to ensure a tight gas seal upon firing.

What Is The .35 Remington Bullet Diameter?
The .35 Remington bullet diameter is the physical width of the unfired projectile seated in the cartridge case. Introduced in 1906 by Remington for their Model 8 semi-automatic rifle (and later famously chambered in the Marlin Model 336 lever-action rifle), the .35 Remington was designed to provide a hard-hitting, medium-bore cartridge capable of taking deer, black bear, and elk in dense timber. Despite the “.35” designation, the bullet measures a true 0.358 inches across.
.35 Remington Bullet Diameter In Inches
According to the official Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) specifications, the .35 Remington bullet diameter in inches is standard at 0.358 inches. Because it shares the same diameter as other popular mid-bore cartridges like the .356 Winchester and .35 Whelen, it utilizes standard .358-inch projectiles designed for medium-bore rifles.
.35 Remington Bullet Diameter In Millimeters
For those using metric measurements, the .35 Remington bullet diameter in mm is 9.09 mm. Because 1 inch equals 25.4 millimeters, multiplying a 0.358-inch bullet by 25.4 yields exactly 9.0932 mm, which rounds cleanly to 9.09 mm.
.35 Remington Bullet vs Bore Diameter
A common point of confusion is the difference between the bullet’s width and the barrel’s internal dimensions. The .35 Remington bore diameter is 0.350 inches. The bore diameter measures the distance directly across the “lands” (the raised portions of the rifling inside the barrel). The unfired .35 Remington projectile diameter (0.358″) is deliberately wider than the bore so the rifling can firmly bite into the bullet jacket, imparting the stabilizing spin required for accuracy.
.35 Remington Groove Diameter
The .35 Remington groove diameter measures 0.358 inches. The groove diameter measures the distance across the deepest cuts inside the rifled barrel. When the 0.358-inch bullet is fired, it swages into the barrel and completely fills the 0.358-inch grooves. This creates a tight pressure seal that traps the expanding powder gases directly behind the bullet, preventing velocity loss and maintaining effective hunting performance.
.35 Remington Bullet Weights
While the cartridge diameter is fixed at 0.358 inches, you can select different projectile masses depending on your hunting application. The .35 Remington bullet weight typically ranges from lighter 150-grain soft-point loads up to the classic, heavy-hitting 200-grain round-nose or modern flex-tip bullets optimized for timber hunting. Changing the weight alters the bullet’s length, trajectory, and recoil, but the outer diameter remains fixed.
Bullet Diameter vs Other Cartridges
Shooters must be careful when comparing caliber names, as cartridge names frequently do not match the physical measurement. Here is how the .35 Remington compares to other mid-bore and popular rounds:
| Cartridge | Bullet Diameter | Diameter In mm |
| .35 Remington | 0.358″ | 9.09 mm |
| .356 Winchester | 0.358″ | 9.09 mm |
| .35 Whelen | 0.358″ | 9.09 mm |
| 9mm Luger | 0.355″ | 9.02 mm |
| .30-30 Winchester | 0.308″ | 7.82 mm |
| .45-70 Government | 0.458″ | 11.63 mm |
Notice that the .35 Remington shares an identical 0.358-inch bullet diameter with heavier big-game cartridges like the .35 Whelen, making it a true mid-bore cartridge that sits comfortably between smaller deer rounds like the .30-30 and massive big-bores like the .45-70.
Bullet Weight
Ammunition manufacturers produce specialized loads for the .35 Remington, heavily tailored for brush and timber hunting where quick, hard-hitting expansion at moderate distances is crucial.
| Bullet Weight | Example Load | Bullet Type | Advertised Velocity |
| 150 grain | Remington Core-Lokt | Pointed Soft Point | 2,300 fps |
| 200 grain | Remington Core-Lokt | Round Nose Soft Point | 2,080 fps |
| 200 grain | Hornady LeveRevolution | FTX (Polymer Tip) | 2,225 fps |
Velocities represent typical factory test barrel data, generally from a 20-inch rifle barrel.
Dimensions
To understand how the cartridge fits into lever-action and older semi-automatic rifles, here are the complete SAAMI-verified .35 Remington dimensions:
| Dimension | Measurement |
| Bullet Diameter | 0.358″ |
| Groove Diameter | 0.358″ |
| Bore Diameter | 0.350″ |
| Case Length | 1.920 inches |
| Overall Length | 2.525 inches |
| Base Diameter | 0.460 inches |
| Neck Diameter | 0.379 inches |
| Rim Diameter | 0.460 inches |
| Maximum Pressure (SAAMI) | 33,500 PSI |
.35 Remington vs .30-30 Winchester
Because both are classic historic timber-hunting cartridges frequently chambered in the same lever-action rifles (like the Marlin 336), shooters frequently compare the .35 Remington and the .30-30 Winchester.
Despite filling a similar niche, they have distinct differences in physical dimensions and ballistic capability:
- Bullet Diameter: The .35 Remington fires a wider 0.358-inch bullet, whereas the .30-30 Winchester uses a narrower 0.308-inch bullet.
- Mass and Momentum: Because of its larger frontal area and heavier 200-grain standard bullet weight, the .35 Remington is often favored for its exceptional stopping power and barrier penetration on big game in thick brush compared to the lighter 150- or 170-grain payloads of the .30-30.
.35 Remington Bullet Diameter: Exact Measurement
The exact .35 Remington bullet diameter is 0.358 inches, or 9.09 millimeters.
While the actual projectile measures 0.358 inches across, it is forced through a barrel with a 0.350-inch bore diameter and a 0.358-inch groove diameter. This intentional sizing ensures the bullet squeezes tightly into the barrel’s rifling grooves. This physical engagement creates a reliable gas seal behind the projectile, preventing the 33,500 PSI of high-pressure expanding gases from blowing past the bullet while stabilizing it for accurate short-to-medium range deer and bear hunting.
