Im looking for a good load using 300 gr,350gr bullet
What do you want to do with the loads? I ask because I shoot mine at about 1450 FPS but some want more. I have been using a duplex load using surplus powder .5 cc of IMR 4198 and 55g of WC860 or WC872. also use a bullet that is cast .001 over bore diamiter. The load is quite accurate and easy on the sholder.
I loaded somr JSP to 2100FPS accurate but will devolop bad habits as it just plan hurts.

Imusing the gun in med.range situation out to 300 yds.pre to use jacketed bulletsand would like2100 to2300 fps.Ive worked a load up using imr 4064 61.0 gr fed 210 primers,shoots about 2199 fps but icant check the pressure.it shoots about 2.5 @100yds

This load shoots good out of my BC, 100yd group, velocity is 2039fps 15' from the muzzle, 45gr IMR4198 and the 350gr Speer gets me 2080fps, but accuracy is not quite as good.

thanks for the info I dont have any h322 how about h335 and what primers,

I haven't used it, but Hodgdon lists it, they list the primers used as CCI200 and Win brass for all load levels in their annual.

My H & R is an Officer's Model Trapdoor.
I find that Reloader 7 the best for all my Trapdoors;especially with the lighter bullets.
