Hi, thinking about joining a local shooting range for use with the HMR and 22.250. Problem is the max bullet velocity allowed on the range is 3000 ft/s. My cureent loads are probably in the 3400 - 3600 range (50g Blitzkings, max load of Benchmark) so thinking of making some heavier loads with less powder.
My rifle is a 1/14 twist 20" barrel so keeping a heavier load (maybe 60-70 grain) accurate is going to be harder (so ive read). I can obviously pull the data and start making some loads up but thought Id ask the experts on the site what loads have worked best for them. Im using Hodgdon benchmark but do also have a tub of Varget I can get my hands on.
Any thoughts? Cheers Steve
