Over the weekend I shot at a match using Sie 130gr TGK, its all I had on hand, to shoot out to 1100 yds. These courses can go out to 1200yds.
ive been doing alot of testing with bullets in the 130-140+ range
130 rdf
130 eld-m
135 a-tip
140 hornady bthp match
140 eld-m
the rdf is a nice bullet but after shooting paper at beyond ,1400-1500y i have noticed those bullets have started to tumble , at grendel mv's this bullet needs a 1-7.5 twist ( im going to retest theese bullets when my new 28" inch grendel barrel arrives )
when it comes tot he 130 eld-m i think the 123 eld-m is a better choice ill take the extra speed over the tiny gain in bc anyday, ive shot to 1560y with the 123g eld-m
the 135 a-tip has proven to be very accurate and does not tumble at extreme ranges ( tested to 1760y) and i can push theese about 100-150fps faster then the 140g class bullets
the 140g class bullets are very accurate in my rifle the bthp is the first bullet i shot a mile with in my grendel , i have not had a chance to check out the eld-m 140 at range yet , and havent been able to check to see if either 140 bullet starts to tumble at extreme ranges yet
