I just received my first order from RMR.
220Gr .400" Plated RNFP- not made by RMR, he is just selling them.
www.rmrbullets.com/shop/bullets/pistol/40-10mm/40-220-grain-plated-round-nose-flat-point-bullets-seconds-new/
I have used these bullets from SNS with good results
www.snscasting.com/40-s-w-220-grain-flat-point-red-coated-1000ct/
Here are the lengths of the projectiles:
SNS HiTek coated = .742"
RMR plated = .687"
These are being used for 10mm subsonic loads, 8" barrel, suppressed.
My current load for the SNS is 4.6gr Alliant Sport Pistol seated to 1.250". (chronoed @ 952fps)
I would like to use the same die setup ( on a Dillon 550B) for both loadings.
That being stated, if I load without changing any die setup, the seated length of the RMR is 1.240", which still leaves more space in the case than the SNS. Both cartridges "ploink" in the barrel at the respective lengths.
Am I correct in my assumption that the RMR loaded round will be a safe starting point with the current powder charge and seated length of 1.240"....?
Thanks in advance of your replies...
