Here's most of the cases I fired at the 600 match Saturday. 2 missing?? I've got 5 firings on a few cases and will find out how the pockets are holding up when I process these. A little bit of cratering. None were difficult to extract (No-Gas).

Shot 600yd Saturday with the 20" 22N, the 80gr ELD handloads, sling and a glove. Only sling shooter there. Saw rests that cost more than my entire rig :) Shot a 481 and didn't come in dead last, but close. Man that was fun. Shot 600 Benchrest (from bags) on Sunday with a .223. That was one...

WOW, wonder where the 64 grains of lead went.

Back from another range trip with two No-Gas AR uppers, 22N and a .223. I'm grooming these for my bi-annual Florida shoot @ 450 yards, and maybe a 600 yard shoot in Pascagoula at the end of the month. Shot 100 rounds of NEW brass through 4th fired brass. The 4th fired was the sharp edged...

Shot up the rest of the Florida reloads today, 80 gr ELD's in the 22N upper. 2 ten shots groups at 100, adjusted right 3 clicks 10 shots, one shot, range called cold. Played with a little +/- around that load but think I'll stick with it for my 600 yard try at the end of the month.

I know I'm smack dab in the middle of a bunch of great long range shooters but I'm really looking forward to shooting 600 with my home made rifle. If I can get an X, maybe even beat some kid, I'll feel lucky. Have to get on paper or they'll toss me out. Unless it's really windy (more than a...

Call me crazy but it looks like the wife and I are going to Pascagoula at the end of the month for a 600yd match. She doesn't know it yet but she will sub for me behind the berm pulling targets so I can watch the other strings. To have a built in excuse, I plan on shooting Open with my 22N...

Thanks. So excited I posted on every forum I belong :) Practiced at 100yds with the 75gr A-Max, Chrono'd my 80gr load, calculated my drop and got pretty close. Looks like 2940fps muzzle and 7 1/4 MOA drop @ 450yds. I see room for improvement, like paying more attention to breath control...

Back from Florida and posting on every forum I belong to :) Just so tickled with my 22N. Here are 2 targets in a 450yd comp I have been practicing for. Long loaded 80gr ELD-M, 2.470", CFE223, CCI 41, No-gas right side charging upper, 20", GS2. Prone, sling, glove, and mat. I WON ! ! ! :)...

Here's a couple of pics with (1) Factory 77 grain fired cases, (2) Twice fired, 77 then 75gr AMAX, (3) Fired 3 times, 77 then 75, 75 AMAX. all of these were originally 77gr Factory, then hand beveled. The last pic is new brass, with a factory bevel, loaded with 80 AMAX and 80 ELD-M for my...

After eliminating the sharp edge case, my brass issues are gone. The new production brass, with the beveled edge does fine. I have a Lee hand prime, don't use it much, but the head fits in the shell holder after 3 firings. No problem. Here is a pic of a thrice fired case with a flattened...

Putting a little bevel on the base took care of my shaved brass issues. I ordered a bag (250) of unprimed new brass and guess what? Beveled edges :) Saves me the trouble.

.300winmag Take your favorite ballistic program and try and find a trajectory that comes close to the Actual (not the JBM values) of bullet drop in the first post. I mean like make up some values and get those drops. I don't know the environmental conditions but use some thin air like 85F...

With 4 shots at each range averages to give a drop, what was the grouping like? Would more shots give a better center?

Your drop @ 200 and 300 is pretty remarkable. Just think if you zeroed at 250 to 300yd.

75gr A-Max long loaded to 2.470" in a 20" ARP barrel. No Gas, single shot. Brass flakes are gone after polishing edges in bolt and base of case. Only loaded a few of each of the following: Reference: 77gr Factory load 3031fps avg, previous trip 3037fps 75A-Max, CCI450, 28.5gr CFE223...

I get 1.114" for the 75gr A-Max. The book OAL for 5.56 is 2.390", I usually load longer for a .223 Wylde chamber and longer yet for a 5.56 NATO chamber. Since either of these lengths require single loading, I'm going to start out close to the lands. I have a lot :) of the A-Max's. I shot...

Deplorable, thanks for the info on charges. I've loaded up a few to test this coming weekend (yes, I know it's only Monday). 28.5, 29.0, 29.5grs of CFE223. Using CCI450 and hopefully I won't run hot before I get to the top load. It looks like my OAL to the lands with the 75 A-Max is 2.480"...

Probably over gassed for the OP, but mine is with gas cut off (might be a little leakage) and single loaded from a sled.

This is what I got after 30 rounds of the 77gr factory ammo. I blame this on the sharp square edge at the base. Will try this for my next outing I'll bevel some new and reloaded rounds and keep a close eye on the bolt face.
