[QUOTE="rooster721, post: 863848, member: 40654"] I just had an 8twist Krieger threaded into my TRG's.. chambering is for a Lazzeroni Firebird & I'm shooting 168 LRX's in it. Just finished my load actually, and it shoots unreal in that barrel-- this pic was a group at 200 during development.. measures .679" center to center of the two furthest holes (I shot three separate groups like that once I finally pinned down a seating depth*) [ATTACH]26508.vB[/ATTACH] I had 3/4"-1" groups at 100 earlier on during development, at 3350, but pressured bad. 3275-ish found another node and got groups just like the pic, but (still) one in three shots gave too-sticky bolt lift* Settled for 3200 and just this-mornin' shot 8 rounds (allowing barrel to cool obviously between every 3) all into roughly 2.5" at 400 while verifying drops* Best consecutive shots of my life!! haha.. I am VERY anxious for season to open up in a couple'a weeks!!! In my opinion, Barnes did a **** good job on those LRX bullets.. it just takes some patience & effort on a "reloaders-part" to dial them in. And possibly a tad faster twist then what is recommended* I'm just a touch below 2000' here at home, and shoot temps anywhere from 30below (celcius) right up to 80F at times.. hunting season however, when I need that thing to perform BEST, is the reason I went with an 8twist over 9.. and I'm glad I did Hope this'll help answer some "un-knowns" for ya guys having trouble with the LRX's [/QUOTE]
