Load testing my Rem Tactical in .223

I've been working with my .223 bolt gun lately. It's a Remington Tactical. I added a Jewell trigger and a Nightforce NX2 but that's about it. I've only had it a year and for most of that year it's just been sitting there waiting for me to shoot it. Too many other guns to play with... It's not my .338 Edge but it shoots pretty well for a factory rifle. That damned Edge has ruined me. I expect all of my guns to put holes in holes at 100 yards and it's not happening. If I shoot 1/2 moa I wonder what's wrong with the load

My first load test was a dismal failure. I loaded them a little hot (not always a bad thing but in this case it was) and rather than say it shot groups I'll say it was more like a spray pattern I went back to the Sierra manual and based my second test on their accuracy load of 20.7 gr of RE-7 and worked down from there in .2 gr increments. So far the Sierra manual accuracy load wins. I'll bracket either side of 20.7 in the future to see if I can squeeze anymore out of it.

The primary purpose of this post is to demonstrate to people that are new to the joy of reloading that a very small powder charge difference will affect accuracy significantly. Load carefully and find out what your rifle likes for the bullet that you are shooting.

The little target circles are 1/2" in diameter. I still don't pay enough attention to cant but I'm getting better. I added a DE cheekpiece and it seems to help with getting on the scope more consistently. I think I still need to work on that as well.

I deviated from the shoot 1 then clean method. I shot 5 from each powder weight, let the barrel cool, and then cleaned. With a little more work on technique I think that I can tighten these up. BTW- I can't recommend Lapua brass enough. It's a joy to work with. I shot the "good" load at 200 yards and had a 1/2" group. I didn't have enough ammo to try 300 yards. Maybe next time.

Re: Load testing my Rem Tactical in .223

hey if you want to try something get you some IMR8208XBR.I have been loading with this powder and have found that it really works great in my 223 1:9 with a 69gn NCC.and it will knock out one nice hole at 100 for me and give me a 1"3/4 group at 300 with little wind.( 15 shoot group )

I worked up to the load that I'am useing .I started at 22.0gn's and went all the way up too 25.0gn's.and yes I watched for pressure signs with each load.started to get flat primers with 23.8gn's in my rifel.25.0gn's gave me too flat of a primer so I stuck with 24.5gn's.and this one load gave great accuracy.but now I have backed down .5gn's to 24.0gn's.I started the test loading all rounds with a 2.290 C.O.A.L. and have stuck with that length.

again its something I worked up too and shoot in my rifel.will even add that this powder seems to be really clean.it only takes a few wet patches along with a few dry to clean my rifel.while brushing with a brass brush between the wet patches.

8208 XBR is a great powder, I like compressed varget for heavy .22cals. Hodgdons max load w/ a 69 gr SIE HPBT is 26.0C of varget @ 3010 FPS. With XBR it is 23.8 @ 2959 FPS. I like to load as full of a case as I can get, seems to bug hole better!

Re: Load testing my Rem Tactical in .223

As soon as I get some breathing room I'm going to load up some test loads with 8208 XBR. I finally got my hands on some.

IMR's data shows max is 23.1 gr / 2,995 fps. It'll be interesting to see what it does.

Varget and Rl15 are good powders for the heavier bullets......

Re: Load testing my Rem Tactical in .223

Couple things
-STOP cleaning between groups. Don't ever do that.
-You need more of a load development plan than trying 3 increments of book loads.

What have you done so far with seating depth?

Not cleaning between groups would be fine with me. I changed to that from lettting the barrel cool and then cleaning between shots which was the recomendation from the guy that wrote the ladder testing article that I read (and can't find at the moment). He also recommended 3 shot groups. I modified the test to use 5 shot groups.

First I adjust the powder charge , then I adjust for seating depth. I started at .020 off the lands. Once I find a charge that I like I'll increment seating depth if it's necessary.
