[QUOTE="scottyd2506, post: 676606, member: 19778"] How is your prograss on those loads? I have been working on the same bullet just recently. My reason is performance. My coyote load has been the 85 Ballistic tips, or the last 8 years the Berger 115 VLD at 3200 fps. after a few years off of hunting, I have witnessed the explosive power of what the Vmax does to coyotes. And other thin skinned bullets like the Varmint Nosler BT (like the 85's I used to use), Speer TNT and Sierra Blitzking. Those ultra thin jacket bullets explode like a shrapnel grenade once they penetrate the inside of a coyote, a combination of velocity and fragile construction. Almost EVERY song dog dies right on the spot, even out of a .223 I like the Sierra 90 Blitzking, as it has a BC of .388, making it the hands down best of all varmint bullets excepet the 87 Vmax in .243 caliber (.400 bc) Back to the Sierra Blitzking, they have a thin jacket up front, so reloading them can be a pain, as the bullet can take damage when bullet seating (in my Redding bullet seater). the case necks have to be trimmed thin, as I have a small expander ball for tighter bullet seating in my bullet dye. My loads I am just working up Rifle 25-06 ruger M77 MkII 26 inch bbl 90 Sierra Blitzking MAX LOADS Rem Brass, CCI BR-2 primmer all 20 Brass weight is 199.5 grains (I sort my brass) Flash hole debur, primer pocket uniform outside necks turned H4350 56.0 =3615 fps (15 ft from muzzle) -this is an old powder lot- groups 3 shots into 0.85 inches @ 100 -0.035 off H4350 55.0 ???? fps (chrono would not work getting late) 0.025 off -same old lot of powder- groups 3 shots into 0.54 inches @ 100 Reloder 19, 56.0 = 3437 fps 57.0 = 3477 fps 58.0 = 3560 fps 60.0 = 3652 fps Not grouped yet H4350 Ext (new lot) 0.020 off rifling 55.0 = 3572 fps groups 3 shots into 0.53 at 100 yrds shooting all off a portable bench that wobbles some is not easy. not as good as the VLD's groups, but not bad. my last 115 VLD group was a 0.50 inch 3 shot groups at 200 yard with the 115 VLD's., but the groups above are still respectable. 90 Blitz my goal is to keep the loads around 3500 fps or just over, as accuracy seems to be better in the 10 twist, if not pushed to over 3550 fps. I was testing loads in 85-90 temps. so I hope around fall winter the FPS drops to 3540-3520 fps or less. my nosler 85 BT's never would group well at high speed, loaded them to 3705 fps and was 1.5 moa, back them down to 3400 fps and 0.75 moa, but that was using H4841. These 90's blasting out to almost 3700 fps still under 1 inch at 100 yrds are impressive for a bullet that is almost .4 bc, But 3500 fps is good enough for 90's, and at 3500 fps brass life will be better, and less stress on gun, more accurate too. (loads safe in my rifle, my factory 25-06 seems to have a tighter neck than others and the fireformed body has larger than norm dimentions (not it is not a improved) and fireformed necks smaller dia.) No real signs of pressure except flat primmer s, all loads have flat primmer s in my 25-06 w rem brass. loads are MAX book listed, but dif lots of powder require new testing. Use cation, and reduce loads 4.0-5.0 grains and work up slowly. Hope your loads are working out for you, let us know! have a great day [/QUOTE]
