.90 grain Bergers or 95 Match Kings at 900?

[Bustercluck]

I noticed a lot of the repliers here have quite fast twist so my question is where do you see the best potential for my setup (1:8 twist tikka ) as far as heavier bullets go? At the moment I have just started loading 69gr smk hpbt and lc brass w/cci 400 and cfe 223 the goal is 600-900m
Not looking for recipes but bullet recommendations, and if I need to jump to br4 primers at that distance (just bought 8lbs cfe .223 and 2000 cci 400 so hoping to use them unless the br4 makes enough difference)

My 24” tac a1 likes 80.5 bergers and varget. They’re the only bullet I’ve tried that would register on the shot marker at 900m.

I like the berger 85.5 and varget, but I’m going to try out n140 this spring. My barrel is a 29” 1-7.5” twist. I haven’t had a problem stabilizing bullets, bjt who knows what’ll happen if I shoot on the beach near the coast some time.

I find the 88 grain hornady shoots roughly the same for me, but I find the odd hornady bullet seems to drop out for no reason every once in awhile. I did a 2 day shoot and alternated the bergers and hornady each string and found maybe 1/20 or something would just hit low, not sure why but I didn’t experience that with the bergers.

I have not really experienced that as far as I know atcany distance. I have in the past had an occasional al bullet not register on a shotmarker at 900 and 1,000 however, but others had the same issue and we just put it down to a big wind change.
We did have one fella with a bullet issue at a match last year but he was shooting a 6.5 or 7 in open, and it was a barrel issue not a bullet issue .

I’ve chatted with a couple other guys about shotmarker and they said this usually happens if the person you’re sharing the shot marker with has their bullet going a drastically different speed than the other. Apprently the latest software upgrades are supposed to straighten that out

Given the massive differences in bullet profiles with more changes likely in the future, I would adjust the throat in a 2nd step after the bullet has been chosen.

Throating reamers are common and very easy to use... even at home. Get exactly what you need w/o the cost and delays of custom reamers.

YMMV
