[QUOTE="Orange Dust, post: 1709979, member: 92702"] Carbon rings can be a contributor to the high ES's you are seeing. Remember, Velocity increase is not linear. 30" should be higher than 26" with heavy bullets and slow powders, but adding 4" To a 26" may not add any more than adding 2" to a 24" if that makes sense. You are seeing velocities that I see with my RUM and a 26" barrel. Pretty high for a WM with any barrel length. The only way it would see increased pressure is from a secondary pressure spike that sometimes happens with combinations slow powders and specific bullets. Don't think it would be consistent with different powders or bullet weights. Bushing the bolt to a smaller dia firing pin, and a heavier spring may allow you to operate at those pressures without cratering and piercing primers, but it will not change pressure. [/QUOTE]
