Hello all,
I;m working with a Remington 700 Classic chambered in 300 savage. As far as standard powders, I can find all the data I need however I'm wanting to try H4198 and IMR4227 in reduced velocity loads with 125 and 150 grain bullets. I've had good success in the .308 with 4198 and the 4227 is calling my name for use in the 300 Savage. The 700 is a little unusual from the other rifles so chambered in that I have a magazine length of 2.800". With the 150 grain bullets I've measured so far, I can seat the bullet .200 deep and take full advantage of the short neck and not infringe on the case as far as powder capacity.
I'm thinking I would need data for charges at 3 different predicted pressure levels of 35,000PSI, 45,000PSI, and 55,000PSI. I know the 55,000 exceeds the SAMMI spec of the 300, but I'm thinking in the 700 with good brass I should be able to exceed the 46,000 SAMMI spec somewhat since the same rifle is chambered in 308 and other higher pressure rounds.
Is there someone here equipped with Quickload who would be willing to do me a favor and run the data with the 2 powders I'm interested in trying? If so, what information do I need to furnish as far as specifics?
Thanks in advance for anyone's help,
Rick

I know it isn't what you asked, but you may find this tidbit useful. In WW brass using a WLR primer, Nosler shows 33 grains of H4198 to be the most accurate charge of that powder under a 125 grain Ballistic Tip. It gave them 2502 fps from a 24" test barrel, and it must be mild since they show up to 37 grains which gave 2832 fps.

Mathman,
Thanks for your response. I can find, although spotty, Data for the H4198 and the 125 to 130gr bullets. I can find no data for the 150gr bullets with that powder. I have interpolated data for the 308 Winchester and have loaded 32grs w/a 150 grain, but haven't had the opportunity to fire them. I think this should be a mild/midrange load. With the 4227 I can find no data so it is completely uncharted territory for me. Speed is not my goal, or I would use a slower powder.
It seems to me with previous experimentation with the 308 Winchester that it takes somewhere in the mid-30,000psi to get proper case seal to avoid case "smoking", but I have arrived at this with no pressure testing equipment and no Quickload data, so it may be and probably is in error.
I've really enjoyed the accuracy, reduced recoil, and reduced noise from the 4198/308 combination, and thinking it would be neat to go another "step" toward a faster burning powder in the 300 savage, thus the curiosity about the 4227. My goal is velocities in the 2200 to 2500fps range with enough pressure to seal the cases, and of course accuracy and low noise. I probably will never exceed the 45,000psi range, but thought it prudent to have the info to at least have an idea of where it goes.
Thanks for your reply,
Rick
