[QUOTE="codyadams, post: 1467283, member: 87243"] I have loaded lots for my cousins rem 700 Long Range in 7mm rem mag, with a 26" factory barrel. You will get best velocity probably with reloder 26, but h1000 and retumbo may get you there too, especially if you throat it for the 180's. Starting off with naked bullets, hornady brass cci 250 primers, I maxed h1000 out at about 2975 with 180 VLD's, then switched to Reloder 26. Maxed about 100 fps more at 3070ish which was a great node, but it was max for the brass and a touch hot, so we backed it down to another good node at 3015. Shot that for a season, now we just hbn coated his 180's, and we were able to hit the next node at 3065-3070 without excessive pressure, and it shoots fantastic. This is in a SAAMI spec chamber. With a custom, 28" barrel, using reloder 26, better brass, and possibly throated for 180's, you will have no problem reaching 3000. In a custom gun honestly, I would twist and throat a 7mm rem mag for the 195's, because it has the hp to push them over 2900 fps, stick a Wyatts extended mag box in, and your gtg. A 195 Berger going 2950+ will kill anything really dead, and will buck the wimd in a fantastic manor. Just a thought [/QUOTE]
