1st I hunt with a Ruger M-77 in .358win , 2nd the Mod 99 is a project gun . I love to hunt with a lever gun my 1st deer rifle is a Marlin 336 in .35Rem love it for thick woods in NY state. BUT as we know you can't just have 1 rifle . I am a .30cal man my son & I got bored and wanted a bigger bore enter the .358 I have not taken a deer with it yet but have taken 2 wild bore with it 1 shot apeice both in the head and like they say" dead right there " off to pig heaven . The Savage started out as a .308win it is a non fancy 1967 "E" model so I did not loose a piece of history , I took it to my gunsmith for reboring during the process the reamer snapped in the barrel [ Good luck finding another ] I found on line PAC-NOR in Oregon for $ 350.00 . PAC-NOR sent to us in the "White" The gunsmith cut it to length 22" ,Threaded ,Chambered , Blued and put the original sights on it for the cost of the re-bore job $300.00 long story short I have been trying it out at the range . 1st time out it would not eject at all no matter what charge I tried they got stuck in the chamber . Back to the Gunsmith for more chamber polishing now it works great only 2 out of 30 rounds fired got it sighted 3" @100yrds 1" or so . I am shooting Sierra GK.225 over 47.0 gr of BL-c[2] 1st time using that powder also used CCI 200 primers not the 250that is why I was asking about the difference load data sorry I took the long way to the point .
