Good for you ! I love shooting 'chucks, wish we had more of them in this area. Don't know where Niter is.

Evidently you are getting pretty good accuracy with the heavy bullets? I've got a few AR's I can only get about 1.5MOA with the lighter 40 and 50 grainers. What type of accuracy are you getting?

72Camaro,
I may have found a really nice round last week with my AR. New barrel and added a suppressor. It's a .223 Wylde, 1:8 twist, 20" long. I was running a bunch of odds and ends factory rounds through it to see what it would do with various brands and bullet weights. Shot a sub 2 inch group at 200 yards and sub 1 inch at 100 (to confirm) with Fed. Premium 77gr. These use the Sierra HPBT. The lighter ones weren't so good.
Hope to confirm these results with this round tomorrow.
I have some other brands that use 77gr bullets I'll try at the range soon to see if it's the brand or the bullet weight.
-Jay

I just happen to have a barrel like you listed that I could not get anything to group well. Don't you have to load the 77's one at a time as they are too long for a magazine?

72Camaro, I was working through latest posts and came across this thread and my post about my luck with Federal Premium Gold Medal Match with Sierra 77 gr HPBT and discovered an unanswered question from you. That was almost exactly one year ago. My apologies for being so slow in responding. This spring I've been experimenting with this load in that same rifle with the 20 inch suppressed barrel and doing some hand loads based on this round. Below is a photo of my last experiment. This is 23.6 grains of H 4895 in once-fired Federal Premium cases using Remington 7-1/2 primers and Sierra 77 grain HPBT bullets. The bullets were seated to the recommended OAL of 2.260 inches so they just fit in the magazine. The test target has 1 inch squares and this was 10 rounds at 200 yards, so if you throw out the two fliers the remaining group is easily 1/2 MOA. My next test will be to load 30 rounds using twice fired Federal Cases (from my stash of Federal Premium Gold Medal Match factory ammo) and test them at 100, 300 and 500 yards. Hope this helps even if it is a year late. -Jay Attachments:

Glad you answered. I've never loaded anything that heavy for .223/5.56 but looks like I may need to expand. I've got my loads for 40 and 50 grain for a couple guns but after that, nothing that is in that type of accuracy. Have some 65's I'm waiting to have time to get to the range, heaviest I've got. What is your fps? 2600? Those are pretty heavy.

I just got back from my 4th year of rockchuck hunting in ID. Took 363 this year in 5 days. Used only a .223 Contender handgun and XP-100 handgun in .22-250. Used 40 gr. BTs in both. Longest shot was just 338 yds. in 15mph winds with the Contender. In the past I used handguns in 6mmAI and .250 Sav. AI. The 40s did as well as the heavier guns and was more tolerable for recoil in all day shooting. I'm sticking with them. I also took 3 chucks at 99 yds. off the same rock with my suppressed Ruger MKIII .22 and Rem. subsonic bullets in 5 minutes. My 4 year handgun total is 785.

Wow! 363 chucks, I'd love to get into that kind of chuck shooting. I live in so. west Idaho and they're pretty shot out here. You see one once in a while on private property or along the hiway. A couple of us make at least one trip every year to the Bliss area but we don't get anything like that kind of shooting.
