After 2 very frustrating range sessions and experimenting with 2 different bullets trying to find a good consistent, accurate load, it all came together. I bought a Savage LRP in .260 last fall and did not get to shoot over the winter but a little experimenting last fall and this spring was frustrating to say the least. I really wanted to get every bit of accuracy out of this rifle because I plan to do some 1000-1500 yd shooting. Well let me tell you I had no idea 0.010in is such a huge deal in seating depth with target bullets. I found that 41.5gr of H4350, Federal Match LR primers and 140gr Berger VLDs are awsome when seated to 2.260 at the ogive and 42gr H4350 same primer and a 142gr SMK seated 2.260 at the ogive are almost as good. here are the two best groups. I now have to load some up and zero the scope and test at long range. The 3 rd groups were shot at 100yds and the Bergers gave me .240in and the SMKs gave me .288in. I know 3rd groups are not as good as 5 but I was in a hurry to try these babies.
Yes it is a 12 LRP. The brass is Winchester 7mm-08 necked down. I chronoed a few loads prior to this but not these. The loads I chronoed were with 142 gr SMKs and H4350. I got a 5 shot avg for the following loads.
2730 fps with 41.5gr H4350
2775 fps with 42.5grH4350
2863 fps with 43.5gr H4350
2918 fps with 44.5gr H4350
