Thread: 284 Win with Hodgdon Superformance

I've ben following these threads on the 284 for while now and eventually got one myself. I've been playing around with superformance and this thread has been interesting. Im not loading myself for the rifle. I leave that to somebody with a lot more experience and expensive equipment.
The rifle is a T3 with a factory 7mm 08 barrel reamed out by gunworks. 18 inch with DPT suppressor and VX5 3 to 15.
using Norma factory 284 brass. 150 grn Nosler accubonds. Fed 210 primer and superformance we settled on 59.6 grms of powder. No pressure signs and shoots into .35 moa at a hundy. ran it over the Labradar this morning for an average of 2875 fps with an Es of 35. Conditions perfect at the range. Have shot gongs consistently out to 610 yrds with this load using applied ballistics.
Did have some trouble at first as the first chrono tried reckoned the load was doing 2840 and we kept shooting over top of the gong. We had to fudge to speed upwards to not shoot straight over the top of the gong. Two shooters and a change to a different scope to eliminate any random errors and variables kept coming up with the same result.
Have not had chance to go back out with today labradar data and shoot out again to see what happens.
Also worked up a load with win760 and 139 ssts. they shot very well but havent had a chance to shoot an animal with them and figured to accubond would be the load to play with for now.
Also had some old brass that came with the rifle of unknown history do have Mark Bridgeman have a look over it and clean it up and trim and resize. We tossed away some that looked tired or with split necks and did a experiment to see if we could find a load that shot the same POI at 50 mtrs for in the bush and that if i lost the brass in the heat of battle its not three dollar a pop brand new brass.
with zero load devolpment we loaded up three 139 grn Hornady interlocks (cos i had heaps lying around that came with the rifle) and went to the range. Norma brass 56 grns of 2209 and CCI primers shot at 50 mtrs on a wobbly rest on a windy day all shot within a 1 inch orange dot. I also ran these over the labradar today and these averaged 2912FPS but with a ES of 81 FPS.
I was happy with that so i have two loads that can be used interchangeably with no change to zero. The accubonds for the open long range stuff ( once i iron out the gremlins with the trajectory ) and a cheap and cheer full load to use in the bush and save the expensive brass and projectiles.
I've shot 4 deer with the new rifle and it has worked as it should, so much so that i sold the 308 and will try having one rifle to rule them all instead of the 7mm rem mag and a 308.
I also had a play at the range the other day with a mild load of 56.5 RL26 and 162 Eldx and 168 Berger's to see if they has potential. Both load shot into a ragged clover leaf with no fuss, so that might be the next development project over the winter when I have some time.
