So I just had a 6 Creed built off my old Vanguard 240 WBY. It's what I had so it's what I used. Went with a 27" BRUX 8 twist Rem Varmint with 3 port lil beast brake, Adj McMillan A5, Timney trigger at 1.5#, NF 20 MOA base, MK4 rings, 8.5-25x MK4
The main plan for this rifle is just a long range coyote and steel rifle out here in EO to 1200 yards. I wanted to shoot the 108g ELDMs around 3100-3150 with H4350. Bought some Peterson LRP brass and this is where it gets interesting...
I started at 39.5g and went to 42g in .5g increments of H4350 with the 108g ELDMs and did 3 shot groups just to get an idea of velocity/accuracy. All went well until I hit 42g which left some nasty gas leakage on 1 of the cases. There were no obvious signs of pressure at 41/41.5/ or the other 2 cases of 42g. So I said ok, well 42g is obviously hot. Velocity was 3150 at 42g. I then came home and loaded up 10 rounds at 41g and went and shot them at 200 yards. I ended up popping 1 primer out the case and had gas leaks on 2 others. Group was 1" at 200 for those 10 shots. Velocity was 3140fps average. This had me pretty pissed off at that point since I was now wrecking brand new Peterson brass .7g below max loads in the Hornady manual. I called Peterson brass and explained my issue/concerns. He basically told me tough shit, you're hot rodding them. He also kept referencing the nosler manual which lists 39.5g of H4350 as MAX load. I said I see that, but I'm not shooting Noslers, I'm shooting Hornadys and their max is at 41.7g so I hardly call that hotrodding especially when everyone and their mom shoots 40.5-41.5g H4350 with 105/108s in a 6 Creed. He then said it didn't matter, load data goes by bullet weight. I thought to myself huh that's kinda funny because different bullets have different bearing surface and lengths, therefore differnece in pressure and load data. So after getting nowhere with him and being super pissed at that point I decided to try a 10 shot ladder and start way low at 37.8 and go to 40.5 in .3g increments. I hit a nice good node at 39.9/40.2/40.5 which resulted in a .8" 3 shot group at 300 yards with an ES of 20 and a Velocity of 3000fps. Going to just load the rest up at 40.2g at 3000fps and call it a day...For reference the Hornady match 108 ELDMs shoot 2980fps and do 1/2 MOA 5 shot groups.
I guess I can live with, but I would've thought a 6 Creed with a 27" tube would shoot a little faster than 3000fps and not be blowing primers and having gas leaks at 3100-3150 fps
Anybody else having issues with Peterson brass? It's my first time using it and honestly not super impressed with it. And definitely not impressed with the ding dong I spoke with. Horrible customer service and communication skills. I will NEVER buy another box of their brass, nor EVER recommend it to anyone at this point. I'm only using it because I don't want to spend another $150 on brass right now. I told the guy I'd ship it back to them and they can replace it. He said nope because you're hotrodding them. He must have told me that 10 times in our conversation. Whatever my guy...
