Blowback Bolt Weight Calculator

Blowback Bolt Weight (grams)	Effect
10	Very light bolt weight may result in increased felt recoil, potentially causing cycling issues due to insufficient mass for reliable operation.
20	Light bolt weight may still cause cycling issues with some ammunition types but might offer slightly reduced felt recoil compared to heavier bolts.
30	Moderate bolt weight likely offers a balance between reliable cycling and reduced felt recoil. Suitable for a wide range of ammunition types.
40	Heavy bolt weight provides reliable cycling with most ammunition types and significantly reduces felt recoil, enhancing shooter comfort and control.
50	Very heavy bolt weight may lead to sluggish cycling in some firearms but offers maximum recoil reduction, ideal for shooters prioritizing comfort.

These are general estimations and the actual effects can vary depending on factors such as firearm design, ammunition used, and individual preferences.
