hi nube
i have a ultralite accumark and lady varmitr has a deluxe. I feel it is the finest caliber for alberta. foxes up to the occasional moose. fast flat and hard hitting
positives:
-undisputed king of .25's
-compared to the 270 (150gr) it kicks less and carries more energy further.
-mine does 100gr tripX at 3550, only mild pressure
-2 3/4 hi at 100 zeroed at 300 yards.
-aim dead on coyote from 25 to 350, 6"ish over back at 500
(Thats with 100gr!!!)
-tho manuals indicate that 75gr crowd the 3800-4000fps, i have never had the need
it absolutely drops everything it connects with
negatives:
-brass is 35.00 for 20
-factory loads is 75+
-full house loads only last three- four refills max.
-26" pipe
-15 -20 rounds between cleaning, any fouling starts to change POI.
You might want to check out the 257stw, googleing it there is very little on it out there.
apparently it routinely pushes 100gr at over 4400. but now you looking at 400-600 rounds between pipes. I heard that corelane sports(?) in dawson creek is doing them. I heard that it has dead on ballistics to 500 yards. if you do find something on this unit... let me know. i cant verify none of it so dont hold it agin me..
