Just an FYI: I've been loading Lees 312-155 Gas check bullet in my sons 1893 Spanish Mauser Carbine .308 conversion, as it will not feed RNs at all! This is a 155 grain Spitzer designed originally for the 7.62x39. It is a rather long nosed bullet, I took a caliper to it and the nose above the crimp groove is .020 shorter than my Lee 200 RN. HMMMM.
So I loaded a few in my Krag cases. Threw them into both my Krags, and they feed just fine. Might even be a tad slicker than my 200 RNs. Out at the farm they shot under 3" at 100 yards, sights still set at 4. 2 grooves, I still get a greasy muzzle on the infantry rifle. All sized to .311 with aluminum gas checks.
This would save me some lead money, and make loading for my son and I easier with only one bullet to cast. Donnie wants to shoot his Isapore SMLE in the EEM, and the Spanish Carbine in the main match. Reason being these are HIS guns, not mine!
But here's a circa 150 grain Spitzer that feeds and shoots just fine in a Krag.
