[QUOTE="Roughwater, post: 671069, member: 33915"] Hi, In between working, vacationing etc I'm still working up loads for my friend's Ruger 270 Winchester based on the 165 gn Matrix VLD hunting bullet. At one point I thought we might be stuck at 2700 Fps velocity but I now have several loads at 2800 FPS or close and not seeing signs of severe pressure. Other than with the MagPro powder however I can't yet vouch for accuracy I am at near max on velocity with these loads so I'll soon be checking accuracy. These are my results thus far. Keep in mind these loads are most likely too hot for some rifles so back off a couple grains and work up. These results are from a 22" barrel. Cases are Norma, primers are WLRM 1,Winchester 780: 60gn = 2820 fps 2. IMR 4831: 55gn= 2752 3. RL-25: 62gn= 2815 - compressed 4. Ramshot Magnum: 62gn= 2825 5. Magpro: 61.4gn= 2770 I used 2 chrony's to obtain the FPS with a Prochrony and a shooting chrony (beta master) directly behind it. Generally the FPS were very close to each other. At 2800 FPS one ballistic calculator showed the following results using a G7 BC of .65 for the 165 gn Matrix VLD. At 300 yds a Drop of 11", velocity of 2624 and energy at 2525 At 500 yrds a drop of 42", a velocity of 2510 and energy of 2310 Terry [/QUOTE]
