Has anybody run a test between the two with the same loads?
I've read that they're interchangeable, no accuracy loss with the cannelure. I've got 1000 of the 77Cs and I'd like to use some up in my fire-forming load for my 223AI, I've shot them in my 223Wylde SPR and they've shot very well 5rds...
I prefer the vertical for prone and sitting (off tripod or bipod), for a stalking/still hunting rifle I like the standard grip.
A couple years ago I put together what I considered to be a "cross-over" rifle for longer shots that has a Manners EH-3 with their more open style grip that's a...
I currently have 5 centerfire presses and 2 shotgun presses.
RCBS RockChucker: solid reliable press, but now regulated to a e-capping station.
Redding Ultra-Mag; bought it when forming a wildcat and loading for BPCRs, it's now my mainstay for rifle reloading.
Dillon 550B: all handgun, 223 and...
Overall it wasn't bad of a wait, the longest pole was the barrel, and IF I hadn't wanted the 400 Mod BB so badly, I could have ordered that from Bugholes or Redhawk and had it in a week.
From yesterday, the last 3 rds at 220yds while finishing barrel break in:
.223 Lapua brass, mixed lot...
Just about finished with my 223AI project. The stock arrived yesterday, got it mounted and added a spare scope today. Still on the search for one I want🥺 The loner is bore-sighted and hopefully I'll start break-in his week.
Specs:
Action: Impact Precision 737R
Barrel: Bartlein 24" 400 Mod B...
Speer 180 HotCor at 2600 (19" barrel) broke the off leg and kept going. I've used yhis bullet/load on 4 hogs now and only recovered one that was quartering towards me at 10'. It penatrated into the hind quarter:
Pretty excellent, surprisingly so.
I would have thought it'd be like grass fed beef, but it's actually way better.
I used my Rem M7 in 350rem Mag launching a 250NPT at 2599FPS at 117yds. Complete penetration, she took a few steps and fell over. About 700lbs (cow) on the hoof.
Past weekend at a friends lease in OK, REM 7600 rebore to 358Win with a SightMark Mini-Wraith at 130yds, was prepared for low-light, but she came out in daylight.
I took a different approach with my 21' long bench.
I sort of lucked out by having a friend that's a cabinet maker. The one thing I didn't want was closed cabinets as I end up opening up doors to find stuff. My reloading area is under my 3 car garage with a vault door and has its own zone on...
You can also use a short cartridge 7600 since the action is the same and the magazine determines the cartridge length. Have JES rebore it and find some long cartridge magazines.
