Thread: Load development in the SI

My rem700 .308 was running 165gr Sierra hpbt on top of 40gr of 2206h at 2.80” getting 2650fps which was super accurate.

I stupidly sold that as soon as I got my kimber which is very light and rather short. So I opted for something in the 150gr weight.

Have tried 150gr sst and a few other projectiles in the weight range.

I’m playing with 150gr nosler BT on 44.0 gr of 2206h, fed primer and brass, loaded to 2.80” which is mag length.

Out of a 5 shot group I’ll get 3 touching, and 2 fliers all MV is within 10fps and I’m pretty particular when I’m prepping and loading.

I tried going up to 44.25 and 44.5 gr but groups opened up.
