7x64 doughnuts

Post by joe rocket »

Middag manne, 'n vriend van my se 7x64 gee doughnuts. 9 uit 10 doppe het doughnuts nadat dit gevuur is. Dit is norma doppe, fiocci primer, hornady 162gr punte en sy spoed is 2680v/sek. Doppe is 2 keer gevuur Is daar ander mense wat met dieselfde probleem sit? Dit is ' styer mannlicher. Ek hoor graag van die wyse manne wat die oorsaak is.

Sjoe, dit is vinnig. My 270 begin eers na so 7 skote. Kamer grote sal moontlik 'n rol speel.

Thanks Joe Rocket, so I've shot 120 rounds in the 7x64 and each and every case has had a doughnut form from the very beginning. Fortunately I have Wilson inside neck reamer so removing the doughnut is easy. However doughnuts should not form after the first firing. Some reload info, TPL is 86.16mm load 50.5 gr S365 using Hornady 162 gr SST @2638 fps.

Joe.

Ek skiet dieselfde koeëls uit my CZ 7x64 teen 2765fps in Sako en Norma doppe 87mm, 53.2gr S365. n Batch sako doppe trek al by hulle 9de skoot met geen probleme nie.

Op my 25-06 met PMP doppe het ek na elke keer een gekry. Gebruik nou sako doppe en die probleem is iets van die verlede.
