Vince, Guy Miner really hit this one out of the park.
On average the BT's just plain shooter better the the AB's.
The 180gr BT will do everything you could ever ask of it out of a 300 WM.
With 180grs of mass you don't really need the bonding. They are accurate, open quickly, leave big holes...
Winnine:
Chambers vary,
Throats vary,
Brass varies,
Powder lotts vary,
changing OAL changes presses
pressure can also very with primes.
I recently started with what I believed was a midrange load in a known rifle.....the midrange load was too hot.... For this particular combination, the...
I put a collapsable on my AR to make it easier for my daughters to shot.
Last weekend my 12 year old put 10 out of 10 in a 6"x10" rock at 200 yards from the sitting position.
Take a closer look.
.17, 20, and 25 are not all that popular calibers.
Hornady match bullets are second rate and don't win any benchrest competitions.
In .224 55gr they suspended the Zmax and the Vmax moly, indicating they will use this capacity to kick out more of the better selling clone...
So you to shoot long range. Here my advice. Don't try to jump from 200 to a 1000 yards.
Move to 300 yards, and once you are shooting MOA at 300 move out to 400 etc.
Find the limit of your existing equipement, then upgrade the weak link, what ever that may be. Yes, at some point you will want...
If you want to shoot long range you need dials and hand loads. Your rig is no better then it's weakest link, and these appear to be yours in the LR game.
Once you are past the point of increasing marginal returns, additional powder typically results in larger groups and higher SD's.
If you are not happy with the accuracy, work with your seating depth, or decrease you powder charge. Your rig may like something a little cooler.
Vince, what are you getting out of those 180gr BT's, 3K, 3100?
At that velocity do you really need the bonded bullet?
The BT's give you sufficent mass, great accuracy, and half the cost.
I'd stick with the 180gr BT's.
SAS, I've seen 100+ fps differences due to primers before.
If you go from a CCI 200 to a WMRP in a .270 Win with H4831, the WMRP will give you an extra 100 fps.
As I keep saying, primers really do matter.
The one line quote from the law is:
"that has physical properties resulting in ballistics performance identical to such ammunition"
Of course the question then becomes, what does that mean?, and that's part of the NRA's suit against the city, i.e. that the law is unconstitutionally vague....
Blc-2, W-760 and H380 are all classic ball powders for the 22-250.
Any one of them paired with a 52gr Sierra MK or similar weight BT and a mag primer should provide bug hole groups in your new shooter.
