sir-slots-alot Posted November 11, 2011 Report Share Posted November 11, 2011 Alan, İ suggest you read my post properly. İ did not suggest a 40 grain .224" versus 40 grain .204" comparison. Not sure you could realistically argue that 40 grains is heavy for the. .204 calibre either. I have read many times that some people have had issues using the 40 grn Vmax in the standard 12 twist tube. Although the some people seem OK - others state they will not stablize properly. When I enquired on this forum concerning the best rate of twist for 39 gn SBK in a 20 cal - the answer came back loud and clear as an 11 twist - so there are no worries. So although the 40 grn bullet isn't a heavy weight - it seems right at the top of what a standard 204 can stablize. Correct me if I am wrong.

baldie Posted November 11, 2011 Report Share Posted November 11, 2011 Spot on Alan. The 40 grain is the most a factory tubed 1 in 12" will [or wont stabilise] . However, as the cartridge rapidly progressed, everyone realised that the manufacturers had got it wrong with the twist. I would class a 40 as the mid weight bullet. A 32 as a lightweight, and the 50 as a heavyweight. The border Archer 1 in 10 [and a bit] is stabilising various bullets up to 50 grainers. Had an old customer in this morning that i rebarrelled a gun for 12 months since, and he gave me a list of what it would shoot with astounding accuracy. However, the 40 grain v-max wasn,t one of them, but it did like 50 grainers, and 39 grain blk,s. Link to comment Share on other sites More sharing options...
Ronin Posted November 12, 2011 Report Share Posted November 12, 2011 I wonder why there is a requirement for "flat shooting" No bullet or cartridge combintion will break the laws of physics. A high BC heavier bullet will always perform better than a low BC light bullet. Is flat shooting a substitute for the inability to get range / drop correct on target? I wonder.... Im with Alan, ive had a 22-250 (AI) for seven or eight years and I use 75g A max in it - nothing ive shot in ("varminting" calibres) comes close for a perfect foxing cartridge.....
