Shwinnng,

"Only someone who shoots/kills as little as you,could botch that obvious. Weight is easily one of the most moot designators amongst a boolits descriptors,as is SD. Only you cited a "130gr 6mm"."

- Well, ya got me on that point. I have not shot a .243 in 27 years +/-. Back in the day a 105 Nosler part was about as stout as I could find to load. As I was loading for heavier game I was looking for more mass, not more speed. Sooo, a 130 gr in .243 woulda floated my boat jest fine.

"As to .243" projectiles of greater than 105 grains weight being mainstays,they most assuredly are amongst some disciplines. 6mm 115's are fairly ubiquitous and from several makers,all of which is well over your head."

- And, again you got me there as well, over my head.

"BC's in that realm will get you to .585 assuming you are "discussing" a G1 drag function. The G7 function will of course be a lesser designator in extrapolation,though of like flight characteristics."

- And again, real big words like gag, er, I mean drag.

"More importantly than lauding BC solely,one should give great thought to terminal affects,a designator conveniently widely missed by both "weight" and "SD" "factors". All boolits of like diameter/weight,share the exact same SD,though it will be "news" only to you. Now despite those moot designators,BC and construction will be vastly different.

- Even vastly different construction as well? Wow! I'd hardly though much beyond the pb. But, I think that is part of what you're trying to tell me here?

"A SAAMI 243Win twisted in accords(1-8" if you've the 115 penchant,which I don't,so stated the 105 plainly from inception) will do very nice things from s/a confines,even in OEM guise. Opt an extended internal box(Wyatt or similar) or opt an extended DBM (HS or AICS namely) and things get even better."

- Hey now, I'm a cutt'n and a past'n al this billnye science stuff to my updated loading manual for sure, thanks!

"In an over the counter modest barrel lengthed rifle chambered SAAMI 243,the .505/105 will do 3100fps,which in a mean-esque atmosphere,will stay supersonic to 1500yds+. The aforementioned 130gr Ballistic Tip can't hang in any realm,but on the bright side it's heavier,burns more powder,is longer,handles/balance worse,kicks harder,costs more to shoot and that horns some folks up."

- But will it kill a deer? The .130 gr BT that is. And no matter what you say, I still like those old Nosler 105s in my.243, so don't even try and talk me outta that!

"Much appreciate your taking the time to extoll your "knowledge"...that was great! I bet you're hell on Humpies."

- And thank you Schweet, for your help here.

Schweeettttttttt, did you note that feint high bypass ratio jet engine-like sound passing over yer head? Fore perhaps...


Now, ass too the Humpy issue, well, I never use a rifle for Humpies, when a 28 gage sxs will do just fine!
