[QUOTE="BountyHunter, post: 229788, member: 12"] James The 300 Varminter can be built on any action. It is really no different than any of the other highly touted wildcats routinely talked about here with zero safety concerns stated. Only major difference I see is that Franklin does not recommend highly temp sensitive surplus powders, which for some ungodly reason has been accepted as a "safe practice" for newbies to load here only. Franklin stated that with the 700 action he was only running them 3800, he was getting 4000 fps in the custom actions. Simple word of caution before you go quoting supposed pressure issues on the internet Quickload projections (by individuals that had a vested interest in a certain outcome) that supposedly projected wild pressures. NO ONE here had the chamber and oal specs so at best, they "guessed" or relied on the QL default settings. QL has many internal settings that you can change that will significantly change the outcomes that cannot be seen on the final sheet. We do not know what settings were used or changed. My QL projections with default setttings were different to say the least. I can change seating depth by .100 and drop another bunch. Besides it is all not relevant with that combination as setup because QL is not configured to compute that. I recently spent about 1-2 hours talking pressures, barrel twists with the Hornady techs at a match. They agreed that the super slow twists such as the 1-17 will radically lower your pressure curves. QL has no provision for taking that into effect and the QL reps say that QL is only built on the industry norms they collected for their data. No one can say that a 300 WSM with a 1-17 twist, zero freebore is anywhere close to the standard data. No that means that we know for a fact that the varminter IS NOT just the standard WSM loaded to stupid pressures. Anyone who says that is making assumptions on things that they do not know. Based on the multiple reports of guys getting similar/close results in their guns, maybe we had a bunch of wailing and moaning about nothing real or are they totally unsafe or lieing too? However, with any wildcat or top end cartridge, guns and chambers will vary, Lot to lot powder variations and primer changes require that the reloader proceed with caution and work up loads for their particular gun and not rely on someone elses data, in particular that is at top end! by the way, [URL="http://www.6mmbr.com"]www.6mmbr.com[/URL] just ran another article on that terrible overpressure (not) inaccurate 300 varminter and shooting ground hogs at 1005 yards in their 24 Sep 08 blog and articles.
