460 reloading questions - 11/29/2015 12:03 PM
I just started reloading for my 460 in preparation of the upcoming gun seasons for deer here in Iowa and want to pick some brains. I have a S&W 460XVR with the 8-3/8" bbl. It wears a Leupold VXIII 2.5-8X32 scope.
I loaded up my 1st 10 test rounds the other day. 5 of them were 45gr of H110, 5 were 47gr of H110 pushing Hornady 240gr XTP MAGs. I used once fired Hornady brass and CCI #250 Magnum Large Rifle Primers. When I went to shoot them I had 8 of the 10 rounds fail to fire. The primers were being struck decently but not going off. Here's a pic of seven of them that were struck but did not fire..........
I had done some research before hand and seen that magnum primers were recommended for the H110 but after seeing the results of what happened and doing a little more research on the internet I've seen other guys have the same issue with CCI Magnum primers not going off. Seems the are harder and have a thicker cup? I Also have some Federal Large Rifle Primers on hand and when I got home I did a test and primed a few cases of empty brass and went out to the garage and fired them off and those primers went off just fine in my gun.
One question......will the Federal primers work just fine while using H110? I believe I have a good crimp on my test rounds if that question arises. I did load up several more test rounds last night using the Federal primers and 45gr of H110 and will try and shoot them today to see what happens.
Have any of you guys had the same issue with the CCI Magnum primers by chance?
Also, on a side note. The 2 rounds I did get to fire had a POI that was several inches higher @ 100 yards than the factory Hornady 200gr FTX ammo I've been shooting out of my 460. I really expected POI to be lower using a heavier 240gr XTPMAG that should be running 250-300fps slower than the factory ammo. Maybe you experts can explain this to me.
Thanks in advance for any/all responses to my inquiry.
