Gotta love it when your first starting load during development starts off like this. Shot two groups to confirm. 1st group was 0.6" for 3 shots, 2nd group was 0.575" for 3 shots. Velocity on the lower end for a 160gr Fox Copper.
Can someone please run quickload so I can have an idea of pressure?
Barnes TTSX 160gr
COAL 3.00"
56 grains cfe 223
24" barrel.
I'm assuming I should be in the 60,000 PSI. No flattened primers, no heavy bolt lift. Tested in both 10deg C and 20 deg C.
I like that. Thanks for the idea, Blue Thunder it is!
Went back and loaded .5 grain more and groups closed up a bit, but perhaps that's also because I had less caffeine that day. Loaded up a few for spring bear, so for now I'm content with accuracy and more than happy with the velocity.
Also working on a new load with CFE223. Out of a 8x57 with a 24" barrel I did hit 3000 fps with a barnes TTSX 160gr, makes just shy of 3200 ft-lbs at the muzzle. So pretty much 7mm Rem Mag performance. 5 shot group averaged 1.25". Will play around with this load in hopes for 3/4"-1".
Picked up a BRNO 21 round top. Dated 1948. Had my gunsmith full length bed it and a pachmayr decelerator recoil pad installed. It'll be rotating between a couple other brno's for spring bear.
Been doing coyote hunting the last bit. Weather was in my favor and in one week got 5 of them from ranges of 60-300+ yards. Here's a few pictures.
Used my Tikka t3x SS in 8x57 on 4 and my howa 1500 SS in 30-06 on 1.
I haven't shot any game with the new ecx but do have a rifle set up with that bullet. I have used the older GMX bullet with good success though. I wish they kept the original shape as the B.C. of that bullet was .450ish if I recall. Makes for a better bullet at 300-400yards. The ecx and it...
Under 25 yards. I would'nt use this bullet past 300 yards with that velocity, especially with the fact the the e-tip is a little harder than Barnes copper bullets.
A late season color phase black bear. Husqvarna 8x57 with irons. Bullet was recovered. 180gr Nosler E-tip all copper at 2550 fps. Recovered bullet weighed 179gr. So the plastic tip is what was loss.
Weighed the bear with vitals and guts removed. Any guesses for weight?
