.303 reloading question

Looking at the Reloaders.net web site, 41gr's of 4895 for a 150gr is 2465 fps. Looking in my books, Speer #11 has MAX 42 gr at 2594fps, #14 has it at 44gr at 2695. Going by the books, you should be ok. Tho I would start about 37 to 38 gr and work up in 1/2 gr increments from there.
Just my 5 cents worth.

Looking at Hornady 9th edition manual, list H4895 for 150 interlock SP start at 29.9 to max of 38.9 . Lyman 49th edition manual lists start of 38 to max 42. IMR also makes a 4895 powder. It's a good idea to have a few reloading manuals on hand to cross reference data before reloading.
It's hot, but the rifles can handle it.
I find I get th best accuracy from loads a bit milder.
With the 150 Hornady, I use 40 grains of 4064, keeping the slightly-slower 4895 for the Sierra 180, with which 38 grains usually gives superb shooting, if a tad mild.
I also seat all my bullets to the OAL of a Ball round: better feeding, milder pressures AND it crowds the leade just a bit, helping the accuracy.
Hope this helps.

I am just using a Lee handloading set. I just loaded up 20 rds of Hornady SST over 38.2gr of H-4895. It should give me around 2500 fps. I seated the bullet to 78mm (3.07 inches) overall length. I will see how this shoots. Thanks guys.

I've had good results in a number of .303s when using RL15, IMR4350, IMR4064, W760, H414,and Varget-all somewhat slower burning than IMR4895 and H4895.
If a person reloads for a variety of MILSURP ctgs and really wants to boil his powder selections down to a single propellant, IMR4064 is good with just about any of the common MILSURP ctgs that I can think of incl 5.56/.223 Rem, 6.5 Swede, 7x57 Mauser, .30-06, 7.62 NATO/.308 Win, .303 Brit, 7.62 Russian and 8x57 Mauser. 4064 is an excellent choice for the M1 Garand as well, both in terms of functionality and accuracy. 4064 is a bit "loggy" in a powder measure, but you can throw charges just a bit below desired weight and then finish off each load with a powder trickler.
