[QUOTE="Gene R., post: 1222012, member: 35256"] I just finished up load development in my buddies 300 wby Accu mark with them yesterday. Powders used RE25, Retumbo, RE33 and Imr 7828ssc. I couldn't find H1000 locally to try it. The gun choose 7828 seated to mag length w/ fed 215's, wby brass, and 76 grs of said powder. I'm getting just a tad over 3/4" @ 100 yds. I haven't got it chrono'd yet but book suggests 2850 fps @76.3grs. It took about 37 rounds to get to that. UGH!!!! By far the most ive ever needed for any one rifle with one bullet. All the slower powder groups opened at top of load data. Even @ 76.3 with 7828 the group grew to over a inch. Knock .3 grs off and just a bit over 3/4". Go figure? Gene [/QUOTE]
