ok my rattler was horrible I wrote a thread on it up all I did from getting a gun which jammed and shot 3 to 4 inch at 50 yards to now shooting sub Moa @ 100 yards
1.so my 30 cAL WAS JAMMING AND SOMETIMES DUMPING BOTTLE AT JAM , issue with this was the magizine actuator had dirt and lead in it , since day I bought it , cleaned it with break clean and sho air and used super lube ,
2, gun shot 4 inch groups at 50 yards horrible , had 3 issues , one issue was barrel needed to be polished had flaws with bore scope , I polished on lathe and I cut a new crown , this made gun go from 4 inch at 50 yd to 2 inches at 100 yard , my spread was like yours close to 100 , also my reg creeped after I adjusted it , that issue was I removed the regulator it was full of rust , I tumbled them in my ss cartridge
SS pin tumbler then I polished them ,
then The creep was when I tightened regulator some rust got onto the delron seat I cleaned it and since I had it in my hand I resurfaced it , this got my groups 1 moa and my fps spread went from 100 to like 10 fps now , then when I removed mag I measured my 30 cAL MAG IT IS ,300 , MY barrel breech is 301 and my muzzle is ,294 , not very thought out I would of liked mad 300 breech 301 and muxxle 298 to shoot ,300 , so
key is ammo must stay in mag and not be loose in my cals , .2995 is best , I would rather use ,296 due to barrel being so small at muzzle and it is unchoked so it is just a odd size , but now with using ,2995 ammo I can group 90 gr at 3/4 inch and 50s about same , nd 50 to 60a about moa at 100 yd and still tight to 200 , I spent alot of time on mine because it was first one I had and second no info out there , not even a diagram , and company never answered me asking for one , I did order spare reg if it ever goes and I ordered a oring kit just to measure orings to make a list and order in bulk , western isnt very end user friendly like fx taipan epic edgun ect , I was disappointed in lack of support spend close to 3k and not even a diagram , geeze I dont need it now but still , since I posted mine I had alot of people find they had same issues and did what I said and they all had identical problems which now were solved LOU
