I have an old 99 take down from 1920. I know the 1:14” twist rate likes 87gr bullets. I was curious if anyone got the 100gr A-frame to shoot well or any other 100gr bullets for hunting purposes?
I got accuracy on the order of inch and a quarter groups with 1:14 twist 99 barrels using Speer 100 grain flat base bullets. I pushed them hard back then but, never had a problem and that is the only 100 grain bullet I used.
@rookhawkThank you for that info. I was wondering if there is a way to examine the ogive or length of the 100gr A-frame compared to the 100gr sierra and 100gr corelokt to determine if its likely or unlikely that the a-frame would stabalize? I should probably measure the twist rate of my barrel too, some of the 1-14” twists were actually more like 1:15, others 1:13. I assume the irregular results come from the fact a few people were lucky and had a twist rate that aided stabilization more than the next batch of barrels.
@rookhawkThank you for your education, @Bob Nelson 35Whelen .
These types of guns/calibers were from the "Gentleman hunter" era in America that predated my life experiences. I don't know anything about 257wby, 257 Rob, 250 Sav, 244 Rem, 25 Newton, and the like.
In fact, the first time I owned a gun smaller than 6.5mm was once I started raising kids and got a pre-64 in .243. For that gun, I just used barnes 80gr TTSX and watched it put down deer with great efficacy in the hands of 7-year-olds.
Based on that line of thinking, I had assumed 87gr speer hotcore and the hornady 87gr varmint that is a knock-off of it would be a bit lethargic for midwest whitetails. I had assumed that if I couldn't go to a bigger bullet due to twist-rate issues, I should at least go to a more durable bullet like an A-frame or something else that would hold together at 3000fps.
I'll look into the 100gr Sierra Hotcore that has a similar shape the 87gr spitzers and go from there.
I still am curious about that 100gr A-frame though...if that would shoot through a 1:14 twist it would be a game changer. That gun would be suitable for a lot of larger/tougher stuff including hogs, stags, black bear, etc. I have no shortage of guns, I just thought it would make it far more utilitarian.
