That is a fantastic posting! I hadn’t at any time found that. I've a buddy that is in a very capturing club with Speedy Gonzales. He definitely understands a whole lot concerning the benchrest world! Thanks for sharing.
Many thanks for sharing these final results. Just like everything else from this weblog it’s really intriguing and useful!
There are many variables linked to hitting extensive array targets that we must always be looking for variables to do away with. If we can easily lessen the odds that a load could shoot speedier in the heat and slower in the cold, it’s a deserving pursuit!
The self funding of Cal’s research and Trump’s candidacy manage to both be coming for their boundaries. Cal has provided us greatly from his daily life’s most valuable asset…his time.
In truth, every now and then We've got witnessed an inversion on the powder temperature – muzzle velocity partnership for a certain wide range of powder where the muzzle velocity actually reduced as the powder temperature amplified.
I loaded Just about every case at what I knew will be a gentle to medium load, in order to stay away from pressure spikes. None of the hundreds have been “tuned” for the particular rifle we were screening with.
When you Test our hundreds against the Hodgdon IMR manual, you will notice that we did not load any of the calibers to the most. We desire mid-velocity loads, that are much easier within the barrel and not so punishing to our shoulders. In addition to, the critters we are searching are not carrying Kevlar vests.
I two other OCD handloaders that I’m superior close friends with run from the exact same experiment. One of them ended up With all the similar order as me, and I think the opposite 1 (who was really Patrick, the male who did this powder exam) stated the Sellier & Bellot primers imr 7977 in stock developed the bottom SD’s for him, but CCI was right at the rear of them.
but after you are out of that place if gains and looses pace. Testing reveals matters ar enot linear For most powders , some have specified temp ranges the place absolutely nothing A great deal transpires and then a steep drop or climb ,you would possibly avrage that but its not genuine.
If you are doing primers, consider Sellier imr 7977 in stock & Bellot primers (at least LR). A buddy turned me on to them, plus they took my SD down from small teens to low solitary digits in six.five Creedmoor. They are cheep and they seem to operate – i’ll have a IMR 7977 lot more facts immediately after capturing them via the rest of the year.
Very first thanks for your time and effort and skills in performing the experiment and Next in answering my concern.
Will probably be intriguing to see if any of the new RL powders start receiving some notice and use. RL16,23 and 26 are imagined to be temperature steady.
Yet another temperature influence from “Precision and Precision For Long Variety Capturing”/ p 86 “Temperature may impact a rifle zero as a result of bedding, receiver and scope becoming created of different content and acquiring distinctive fees of thermal growth.
Thanks for the reference. Required reading through. A paradigm changer. I might have additional two a lot more conclusions and restate one particular conclusion”
