Re: .223 wssm question
I have a win M70 coyote I use for yotes and have shot one out as far as 300yrds with it. My gun loves BLC2 (hodogen) with the 55grn V-max. Have never had a coyote get up after just one shot. At the range it shoots 1/2"-3shots @ 200 yrds with this load. Off a rest it will break 6" diameter (stationary) clay pigeons at 500yrds. It is topped with a Leupold VX-III varmint hunters 6.5-20X40 (not under $300) but I have had great success with a burris ballistic plex on my regular .223rem out to 300yrds. As for the 75gr bullets I have bought factory loads but never shot them. Hodogens website lists load data for 75gr V-max but be careful loading. Do some pressure tests like start 3grains below max and slowly increase to maximum charge. Just an FYI my win topped out way before max load with a sticky bolt and buldged primers. Good luck with the 75gr, I'd be happy to hear results.
