Just finished building a 300 Ham’r AR-15. Been seeing lots of videos of the 350 Legend on YouTube. Has anybody shot both 300Ham’r and the 350Legend. Just wanting some input
I did real world (as in killing hogs) bullet testing for both Hornady and Speer and cartridge case testing for both Federal and Starline in early 2019 and as far as I know killed the first hog with the .350 in May (180gr Speer HOT-CORE) so I have some experience with it. Also in full disclosure I have to admit that I've always been a bigger is better kinda guy when it comes to bullets, with the 9.3x62 and it's 286gr bullet being my "favorite" caliber. Here's my honest take on the comparison.
At under 150yds it's hard to argue with bullet mass and diameter, so the .350 probably gets the edge for terminal performance here.
The 300 will shoot flatter and retain more velocity so it has the edge at over 150yds
No real comparison on accuracy, my average 300 loads are more accurate than my BEST .350 loads. I've shot LOTS of sub-1/2" groups with the 300 and very few sub 1" with the .350. FYI the 170gr Hornady Interlock is the most accurate bullet I've found in the .350 and would be my choice for hunting.
AR15 platform guns have to be set-up exactly right to function most of the time with the .350, almost anyone can build a 300 that functions 100%. Personally I think the .350 is a better choice in a bolt gun.
Being limited to a 10rd magazine capacity I don't see any defensive/tactical application for the .350.
I'm at a loss as to why Winchester spec'd a .355" bullet diameter???? The caliber is basically limited to bullets that are specifically designed for it.
Also no real comparison when it comes to versatility in the AR platform or as a handloaders cartridge, with at least 31 good bullet choices, the ability to make cases from 5.56 brass, multiple magazine choices of various capacity up to 30rds and total reliability in the AR15 platform the 300 wins hands down.
