!st: what is the twist on your barrel?
2nd: Was your brno in 222 or 223 originally?
3rd: what powder are you using?
Yes ,the 240 smk are crushing the powder, that is normal, specially if you use a 222 magazine in your rifle which is shorter than a 223 mag.
I went to the range today and tried the 208 amax, right in the land, with 8,7 gr of vita n110. I got a nice cluster at a 100yards. The only problem is that i had to single load each round because they were to long for my mag.
consistency in you reloading is important (I turn my necks, weight each charge to 0.1 grain), weight my cases.
And consistency in your shooting is important as well:
a rear bag below the but is a must when shooting of a bipod or a front bag.
If your rifle is heavy it helps as well to control it when that slow bullet is still traveling down the barrel under recoil...

G'day D-mon,
I was only over your way a month ago, spent 4 weeks on the South Island. We got both of those polar blasts that came through, I've never seen so much snow. Bit of luck and I'll be over there for the roar next year.
I've been using AR2205, with very little success, similar to H110. I've now ordered some N110 after yours and Alley cats advise. I shoot off a bench with tripod and rear bag so all good there and I'm using a 16 x scope for load development to try and eliminate any physical influence.
The barrel is a TSE 1:8 at 18 1/2 inches and mid weight, my Brno was originally a .222.
When the powder and prodgies turn up i'll seat them right out to the lands and post back here. Cheers heaps for the advice.
P.S. Go the Walabies
