My first thought was oil on the primers.

I had the same problem using CCI primers with several types of powder in the 348. I changed to Winchester LR primers and it solved my problem. I would also try incresing your powder charge and stay away from loads with a lot of airspace.

I agree, most people find the Winchester LR primers a bit hotter. Still, you shouldn't have that much trouble with a single base powder. You do probably want a 70% fill or better. I'm not sure where 50 grains of 4895 lands in that regard. I'll have to check QuickLoad on that.

I was using 3031 and RL7 one day when it was 60 degrees both worked fine and several days later the temp dropped to 20 degrees and I started having hangfires with the same loads that were fine before. I have had real good luck with RL7 as long as I use 45.0 grains but when I dropped to 43.0 grains with CCI primers the hangfires started. I ended up pulling the bullets and starting over with WLR primers. I have loaded some with Puff-Lon but I have not had a chance to try them yet, trout season opened.

Lymans #45 load book has a accuracy load of 53 grs of IMR4895 for 2450fps from a 24" bbl with the 200 gr hdy. 4895 is temp sensitive I used the above load for years was in the Big Hole elk hunting a few years ago in 0* & 20 below my load was 10-12" low in that temperature. Had some 250 gr bear loads with AA4350 still low now I use RL-15 and am working on RL-17. going to a mag primer will solve some temp problems but not all you have to change powder I prefer extruded powder over ball powder as Snooky Williamson said it was made for winchester rifles. danny

QuickLoad says that's 81.6% fill with the Hornady 200 grain seated for a 2.795 OAL. It shows a peak pressure of 32.4kpsi and a muzzle velocity of 2390fps from a 24" barrel. Case water capacity is 75.0 grains with a case length of 2.255".

I've not measured a Hornady bullet to make sure it's the same dimensions that QuickLoad thinks. I usually do that and measure some cases for water capacity before I look at things too closely in QuickLoad.
