Thread: Handloading for Placid and Challenging Cartridges

i was very lucky with the 416 Remmy. First lot of handloaded cartridges done by a reloading guy in CHCH (barnes x points 340gr) with a fireforming load would do under MOA at a hundy for 3 shots.
Repeatable.
Then I did my own with 340 woodleighs and 2206. Both myself and my friend trying it out with the second load tried got similar groupings of approx 17mm x14mm at 40 yards out the back of his place. Picked a starting load 2.5 grains back from the max load. This was when the ADI book only had a max load from the picture I took of the page.
Went a whole grain higher just because, and that was the one with the groups just mentioned.
Never sighted it in properly for those as i still had a handful of the monos to use. These chronographed over 2700fps which was the book velocity for a standard load. so i left it
Fast forward years later and I let an acquaintance have a crack. Using my projectiles and his 2206. He used a starting load similar to mine and was getting 2500fps and change and about MOA at a hundy.
I do have some factory stuff to try for shitz and gigs but i do want to load up some more of the woodleighs.
Even though it does shoot well with the 340 cup and core, it also did well with a slower load (i did have the chance to crony the last few i had recently but only thought of it after the fact), and they would be longer so could be getting close to the traditional 400gr projectiles for them and in reality, the twist should be right for that as that is benchmark projectile for them.
The manual does suggest that you could get 2900fps out of a 300gr pill. That is fair stonking.
