Frequently Asked Questions

What are the recommended powders for .223 Remington with 40gr V-MAX bullets?

For .223 Remington with 40gr V-MAX bullets, Vihtavuori N120 and N133 powders were tested. While N120 showed potential for accuracy with specific charges, N133 demonstrated better velocity consistency, particularly at 24.5 grains, making it a promising option for precision loads.

What are the key objectives of this .223 Remington reloading video?

The primary objectives are to fireform 50 new pieces of brass for a .223 Remington rifle and to test Vihtavuori N120 and N133 powders with 40gr Hornady V-MAX bullets, evaluating their ballistic performance and accuracy.

What rifle was used for the .223 Remington reloading tests?

The tests were conducted using a Remington 700 Varmint Special rifle, which was originally chambered in .222 Remington and features a 1 in 14 twist barrel, suitable for lighter bullets like the 40gr V-MAX.

What were the results of testing Vihtavuori N133 powder with 40gr V-MAX bullets?

At 24.5 grains, N133 yielded a 0.42-inch group with excellent velocity consistency (SD 14.6, ES 35). A 25.0-grain charge resulted in a larger 0.87-inch group with an SD of 16.7, indicating potential pressure or consistency issues at higher charges.
